Changes in skin surface patterns with age

R M Lavker, F Kwong, A M Kligman

    Journal of Gerontology
    |May 1, 1980
    PubMed
    Summary

    Aging significantly alters skin surface patterns, especially in sun-exposed areas. Protected skin shows minimal changes with age, indicating environmental factors impact skin aging.

    Area of Science:

    • Dermatology
    • Skin Aging Research
    • Microscopy

    Background:

    • Skin aging is influenced by intrinsic (genetics) and extrinsic (environmental) factors.
    • Understanding age-related changes in skin surface morphology is crucial for dermatology.
    • Previous studies have highlighted environmental impacts on skin, but detailed surface pattern analysis across age groups is limited.

    Purpose of the Study:

    • To investigate the effects of aging and environmental exposure on skin surface patterns.
    • To compare age-related alterations in protected versus exposed skin regions.
    • To utilize cyanoacrylate skin surface biopsy and light microscopy for detailed pattern analysis.

    Main Methods:

    • Collected cyanoacrylate skin surface biopsies from protected and exposed skin areas.
    • Recruited participants from two distinct age cohorts: young adults (20-25 years) and older adults (68-75 years).
    • Analyzed skin surface patterns using light microscopy.

    Main Results:

    • Skin surface patterns were markedly altered in exposed areas of older subjects.
    • Protected skin in older subjects exhibited only slightly altered patterns compared to younger individuals.
    • Aging effects on skin surface morphology are significantly exacerbated by environmental exposure.

    Conclusions:

    • Environmental exposure, such as UV radiation, plays a critical role in accelerating skin aging.
    • Skin surface pattern analysis can effectively reveal age-related changes and the impact of photodamage.
    • Protecting skin from environmental aggressors can mitigate significant age-induced morphological alterations.
