Why Science? | Skin Diseases & Wound Repair

Three students sit around open books and worksheets at a classroom table, reading, writing and discussing the work together.

eduKateSG · Why Science?

Read the skin as a living barrier—connecting cells, microbes, immunity, pigmentation, wounds, materials and patient-centred translation

A fact-checked guide to LKCMedicine’s Skin Diseases & Wound Repair programme and its research on conditions prevalent in Asian populations.

Full chapter index · Science Learning Hub

LKCMedicine says its Skin Diseases & Wound Repair programme studies conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing.

The programme works with partners including the Skin Research Institute of Singapore, NHG hospitals, the National Skin Centre, A*STAR Skin Research Labs and the Asian Skin Biobank.

Did you know? Successful wound repair must restore a protective, functional tissue—not merely make the surface look closed.

This guide provides no skin diagnosis or treatment advice. Sources were checked 11 November 2026.

CHAPTER 1 OF 17 · Understand the barrier

1. Understand the skin barrier

Back to contents

The skin barrier combines cellular layers, lipids, proteins, microbes and immune defences. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 1 follows mechanisms from tissue context to safe, equitable translation.

Measure structure, permeability, hydration and function with body site and context. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

A surface image cannot reveal every barrier process. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Explore “Understand the skin barrier” using a fictional tissue model or de-identified table. Define the barrier function, cells, microbes, measurement, comparator, follow-up and safety endpoint, then state which human evidence would be needed before translation. Build a barrier model. Do not sample, injure or treat real skin. Avoid personal diagnosis and keep all experiments within approved, safe educational materials.

Did you know? Skin differs across body sites and changes with age, climate, ultraviolet exposure, hormones, immune state and everyday products. Chapter 1 shows why research relevant to Asian populations needs careful representation and why a promising material or molecule must be tested for function, irritation, infection risk, scarring and long-term outcomes.

Capabilities include cell biology, dermatology, immunology, microbiology, pigmentation science, biomaterials, RNA biology, imaging, biomechanics, bioinformatics, clinical research and patient engagement. Current programmes determine qualifications. Students can begin with barrier models, diffusion, microscopy, fair comparisons, wound-healing graphs and respectful language that separates variation, disease, mechanism and treatment evidence.

CHAPTER 2 OF 17 · Understand the barrier

2. Study Asian skin diversity

Back to contents

Relevant research represents variation in ancestry, pigmentation, climate, culture and exposure without stereotyping. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 2 follows mechanisms from tissue context to safe, equitable translation.

Record recruitment, measurement and context transparently. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

A broad ethnic label is not a biological mechanism. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Explore “Study Asian skin diversity” using a fictional tissue model or de-identified table. Define the barrier function, cells, microbes, measurement, comparator, follow-up and safety endpoint, then state which human evidence would be needed before translation. Design an inclusive sampling plan. Do not sample, injure or treat real skin. Avoid personal diagnosis and keep all experiments within approved, safe educational materials.

3. Map skin inflammation

Back to contents

Skin inflammation involves immune cells, signals, nerves, vessels and barrier disruption over time. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 3 follows mechanisms from tissue context to safe, equitable translation.

Combine molecular, cellular and clinical measures. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

Redness or one cytokine cannot identify a single cause. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Explore “Map skin inflammation” using a fictional tissue model or de-identified table. Define the barrier function, cells, microbes, measurement, comparator, follow-up and safety endpoint, then state which human evidence would be needed before translation. Draw an inflammation network. Do not sample, injure or treat real skin. Avoid personal diagnosis and keep all experiments within approved, safe educational materials.

4. Study the skin microbiome

Back to contents

Microbial communities interact with sites, products, immunity and environment. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 4 follows mechanisms from tissue context to safe, equitable translation.

Standardise sampling, controls, sequencing and absolute or relative abundance. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

Association with a microbe does not prove it caused disease. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Explore “Study the skin microbiome” using a fictional tissue model or de-identified table. Define the barrier function, cells, microbes, measurement, comparator, follow-up and safety endpoint, then state which human evidence would be needed before translation. Audit a microbiome study.

5. Research acne

Back to contents

Acne involves follicles, sebum, keratinisation, microbes and inflammation in variable patterns. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 5 follows mechanisms from tissue context to safe, equitable translation.

Use defined phenotypes, sites and longitudinal outcomes. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

One microbial shift cannot explain every case. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Atopic dermatitis involves barrier, immune, microbial and environmental factors with diverse trajectories. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 6 follows mechanisms from tissue context to safe, equitable translation.

Measure severity, symptoms, function and quality of life over time. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

A biomarker alone cannot define personal treatment. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Pigmentation depends on melanocytes, melanin production, transfer, distribution and environmental signals. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 7 follows mechanisms from tissue context to safe, equitable translation.

Use calibrated, respectful measurements and appropriate comparators. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

Pigment variation is not itself disease. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair.

Ageing changes cells, matrix, repair, vessels and barrier through intrinsic and environmental processes. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 8 follows mechanisms from tissue context to safe, equitable translation.

Separate chronological time, exposure and functional outcomes. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

One appearance measure cannot establish biological age. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair.

Scar outcomes depend on inflammation, matrix deposition, tension, location and individual biology. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 10 follows mechanisms from tissue context to safe, equitable translation.

Track structure, symptoms, function and long-term change.

Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

Less visible scar does not automatically mean better function. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair.

A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

Killing fewer bacteria is not automatically safer or effective. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.

Explore “Explore antibiotic-free strategies” using a fictional tissue model or de-identified table. Define the barrier function, cells, microbes, measurement, comparator, follow-up and safety endpoint, then state which human evidence would be needed before translation. Design a comparison matrix. Do not sample, injure or treat real skin. Avoid personal diagnosis and keep all experiments within approved, safe educational materials.

Did you know? Skin differs across body sites and changes with age, climate, ultraviolet exposure, hormones, immune state and everyday products. Chapter 15 shows why research relevant to Asian populations needs careful representation and why a promising material or molecule must be tested for function, irritation, infection risk, scarring and long-term outcomes.

Capabilities include cell biology, dermatology, immunology, microbiology, pigmentation science, biomaterials, RNA biology, imaging, biomechanics, bioinformatics, clinical research and patient engagement. Current programmes determine qualifications. Students can begin with barrier models, diffusion, microscopy, fair comparisons, wound-healing graphs and respectful language that separates variation, disease, mechanism and treatment evidence.

16. Translate with safety and equity

Back to contents

Translation needs representative evidence, usability, affordability, regulation and meaningful outcomes. Skin and wound-repair science examines a living barrier where cells, microbes, immunity, nerves, vessels, pigments and physical forces meet. LKCMedicine says its programme focuses on conditions prevalent in Asia, including acne, atopic dermatitis, pigmentary disorders, chronic wounds and ageing. Chapter 16 follows mechanisms from tissue context to safe, equitable translation.

Engage patients and clinicians throughout staged evaluation. A rigorous study specifies body site, skin layer, cell or microbial community, phenotype, ancestry or environmental context, intervention, comparator and time. Imaging, histology, sequencing, biomechanical tests, organotypic models, biobanks and clinical studies answer different questions. Standardised sampling, diverse recruitment and repeated validation help separate a mechanism from site, batch or population effects.

A technically elegant product may widen access gaps. Skin evidence is easy to overgeneralise. A photograph, microbiome pattern, pigment measure or molecular marker cannot diagnose a person by itself; a laboratory wound is not a whole patient; and faster closure may not mean durable, functional repair. Qualified clinicians, ethics review, regulated studies and current product guidance govern diagnosis, medicines, devices and wound care.
