There are two main processes that induce skin aging: intrinsic and extrinsic. A stochastic process that implies random cell damage as a result of mutations during metabolic processes due to the production of free radicals is also implicated. Extrinsic aging is caused by environmental factors such as sun exposure, air pollution, smoking, alcohol abuse, and poor nutrition. Intrinsic aging reflects the genetic background and depends on time. Various expressions of intrinsic aging include smooth… Expand

Studies in cutaneous aging: I. The elastic fiber network.
TLDR
It is proposed that one of the features of cutaneous aging is a slow, spontaneous, progressive degradative process inherent in the elastic fiber that can be enzymatically accelerated from decades to hours by elastase and chymotrypsin. Expand
Skin changes in menopause.
TLDR
Skin signs and symptoms were examined in 46 menopausal women prior to estrogen replacement therapy, suggestive of a relationship between premature aging of the dermal elastic fibers and estrogen deprivation. Expand
Sun-induced aging. Clinical and laboratory observations in man.
TLDR
Individuals exposed to intense UVB from sunlight coupled with intense UVA from suntan parlors are likely at increased risk of skin cancer. Expand
ACUTE EFFECTS OF NEAR ULTRAVIOLET AND VISIBLE LIGHT ON THE CUTANEOUS ANTIOXIDANT DEFENSE SYSTEM
TLDR
Partially impairment of the cutaneous antioxidant defense system by near ultraviolet/visible light, showing that the most susceptible component in skin is catalase, suggests possible pharmacological interventions. Expand
Aged skin: a study by light, transmission electron, and scanning electron microscopy.
TLDR
The fine structural organization of the epidermis, dermal/epidermal junction, and dermis from an unexposed site of elderly people was compared with the organization of a similar region of young people to show structural evidence that barrier ability is not compromised in senile skin. Expand
Tazarotene—first of a new generation of receptor‐selective retinoids
TLDR
In vitro, animal and clinical evidence reveals that topical tazarotene modulates all three pathogenic factors in psoriasis: abnormal keratinocyte differentiation, hyperproliferation, and increased expression of inflammatory markers. Expand
Lipid pigment (lipofuscin) in human perioral muscles with aging
TLDR
Accumulation of the pigment in the perioral muscles with aging was found to be similar to that in the myocardium and tongue muscles. Expand
Photoprotection in vitiligo and normal skin. A quantitative assessment of the role of stratum corneum, viable epidermis and pigmentation.
TLDR
It is found that Hyperkeratosis in vitiligo offers just as efficient photoprotection as does the normal stratum corneum in pigmented skin. Expand
Reduced type I and type III procollagens in photodamaged adult human skin.
TLDR
Collagen precursor levels were significantly correlated with the severity of photodamage, but not with chronologic age, and it is likely that changes in collagen precursors lead to reduced levels and/or altered organization of fibrillar collagen, and thus may contribute to the wrinkled appearance of Photodamaged human skin.

TLDR
Telomere length is a biomarker of somatic cell aging in humans and is consistent with a causal role for telomere loss in this process, and fibroblasts from Hutchinson-Gilford progeria donors had short telomeres, consistent with their reduced division potential in vitro. Expand
