Solar exposure(s) and facial clinical signs of aging in Chinese women: impacts upon age perception.

A new reference clinical atlas of facial signs dedicated to photoaging was applied to 301 Chinese women of various ages through standardized photographs. Such approach aimed at better describing the facial changes induced by both real/chronological age and sun exposure and their respective impact on two subcohorts of different behavior with regard to sun exposure. A total of 28 various facial signs were individually graded according to their severity by a panel of experts, and a perceived apparent age of each subject was assessed.

Effect of the sun on visible clinical signs of aging in Caucasian skin.

Objectives: AGING SIGNS CAN BE CLASSIFIED INTO FOUR MAIN CATEGORIES: wrinkles/texture, lack of firmness of cutaneous tissues (ptosis), vascular disorders, and pigmentation heterogeneities. During a lifetime, skin will change in appearance and structure not only because of chronological and intrinsic processes but also due to several external factors such as gravity, sun and ultraviolet exposure, and high levels of pollution; or lifestyle factors that have important and obvious effects on skin aging, such as diet, tobacco, illness, or stress. The effect of these external factors leads to progressive degradations of tegument that appear with different kinetics.

Photoaging of the chest analyzed by capacitance imaging.

Objective: Capacitance imaging is a new technique using sensors based on silicon technology developed to record fingerprints for security reasons. Applying such a sensor onto the skin surface gives the capacitance (hydration) map of the skin surface with a two-dimensional resolution of 50 microm. This method was used to characterize skin of the chests of 64 women with various grades of skin photoaging.

Beneficial use of Cetaphil moisturizing cream as part of a daily skin care regimen for individuals with rosacea.

Introduction: Rosacea is a common and chronic disorder characterized by flushing, erythema, papules, pustules, and telangiectasia on the central part of the face. Because the facial skin of individuals with rosacea is particularly sensitive, irritants can trigger a worsening of the signs and symptoms of the disease. This enhanced sensitivity is thought to be linked to a deficient stratum corneum barrier function.

Beneficial effect of a moisturizing cream as adjunctive treatment to oral isotretinoin or topical tretinoin in the management of acne.

Despite their beneficial effects on the treatment of acne vulgaris, topical and oral retinoids may cause severe local irritation (retinoid dermatitis) due to their mechanism of action, thereby jeopardizing patient adherence, and thus compromising treatment efficacy. Alleviating dryness and improving skin comfort by using a moisturizer concomitantly to retinoids could enhance efficacy. In the present study, 30 subjects receiving either oral isotretinoin for at least 2 months or topical tretinoin for at least one month applied a moisturizing cream (Cetaphil Moisturizing Cream) twice daily for 15 days on one half of the face while the other side remained untreated.
