Skin aging appears to be the result of both scheduled and continuous “wear and tear” processes that damage cellular DNA and proteins. Two types of aging, chronological skin aging and photoaging, have distinct clinical and histological features. Chronological skin aging is a universal and inevitable process characterized primarily by physiologic alterations in skin function. In this case, keratinocytes are unable to properly terminally differentiate to form a functional stratum corneum, and the… 
Oxidation events and skin aging
Skin changes in indian elderly : a clinical study
A thorough knowledge of the skin changes in elderly is of prime importance for the dermatologists to improve quality of life of elderly.
AQP5 regulates the proliferation and differentiation of epidermal stem cells in skin aging
AQP5 regulated the proliferation and differentiation of epidermal stem cells in skin aging, and it may play an important role in the balance of proliferation and differentiated skin cells in aging.
Apigenin as an Anti-Aging Skin Treatment V
The findings support the evidence that apigenin can improve several markers of aging and use in skin care products may contribute to objectively improved parameters of skin health and subjective appearance of photo-aged skin.
Increase of stratifin triggered by ultraviolet irradiation is possibly related to premature aging of human skin
Stratifin affects the water‐holding capacity, barrier function and dermal matrix components in photoaging skin, and an increase of SFN triggered by UVB irradiation may be one of the causes of alterations observed in photo aging skin.
Evaluation of the efficacy and safety of “ Anti-Wrinkle cream ” in the treatment of facial skin wrinkles : A prospective , open , phase III clinical trial
A significant improvement application in almost all persons and also, th reactions, with excellent overall compliance are observed, and it may be concluded that “Anti-Wrinkle gement of facial skin wrinkles” is effective and safe for usage in the mana.
The efficacy and safety of an antiaging topical serum containing hesperetin and sodium cyclic lysophosphatidic acid: A singlecenter clinical trial
Intrinsic skin aging leads to dryness, wrinkling, epidermal atrophy with decreased rete ridge height, reduced collagen synthesis, and loss of normal elastic fibers.1 In contrast, extrinsic skin aging
Survey on skin aging status and related influential factors in Southeast China
Age, solar-exposure time, Fitzpatrick type and skin type are the associated forces in promoting skin aging, and emotional factor seems to be another independent risk factor.
Skin Health Connected to the Use of Absorbent Hygiene Products: A Review
A holistic approach of using high-quality absorbent hygiene products in combination with appropriate skin care will help maintaining good skin health.


Assessment of ‘Dry Skin’: Current Bioengineering Methodsa nd Test Designs
The quantification of skin surface topography and the mechanical properties of skin are suitable methods to characterize a dry skin condition and for clinical assessment of moisturizing products and emollients.
The importance of skin barrier function
The prevalence of atopic eczema and other dry skin conditions is increasing, suggesting that environmental factors are of major importance in its aetiology. The stratum corneum provides the epidermal

The study suggests that measurement of skin friction can be used to predict the degree of liking of moisturizers, and that skin care products may penetrate and influence the structure and function of the skin.
Persistence of both peripheral and non-peripheral corneodesmosomes in the upper stratum corneum of winter xerosis skin versus only peripheral in normal skin.
It is revealed that the nonperipheral corneodesmosomes, which are totally degraded during maturation of the stratum corneum in normal skin, persist in winter xerosis, probably leading to abnormal desquamation.
Cigarette smoking-associated elastotic changes in the skin.
Cohesion and desquamation of epidermal stratum corneum.
The effect of glycerol and humidity on desmosome degradation in stratum corneum
One of the major actions of moisturizers in vivo is to aid the digestion of desmosomes which are abnormally retained in the superficial layers of xerotic stratum corneum, according to this investigation.

The chemical and physical properties of epidermal lipids are reviewed and a structurally unusual acylglucosylceramide is thought to be involved in assembly of the lamellar granules, and a related acylceramide may have a major influence on the organization ofThe lamellae in the stratum corneum.
The influence of stratum corneum morphology on water permeability.
The permeability (P) and lag-time (Tlag) for water vapor transport through the SC is found to be about 1000 times less than the values obtained for most other lipid membranes, and the intrinsic diffusion of water is comparable to values obtained withother lipid membranes.
