Skin texture

To be effective, this method must be carried out on samples which have been blanched, and upon peas from which the skins have been removed. The heat applied in blanching drives off gases entrapped in the tissues, and removal of the skins is required to remove air that may be entrapped under them, although it materially slows up the operation and makes it very tedious. In order that there may be consistency in grading, the test must be conducted under closely standardized conditions of temperature and solution concentration. This becomes of considerable importance in borderline cases, and failure to take it into consideration no doubt accounts for some of the inconsistency in results experienced by the industry. The test is not a true measure of tenderness, in that it accounts for variation in skin texture only in so far as maturity affects skin texture. Skin texture is affected by factors other than maturity (4). Other methods for the estimation of maturity based upon density or specific gravity have been suggested by Jodidi (16) and by Lee (22). 

Jessner s solution contains 14% resorcinol, 14% salicylic acid and 14% lactic acid. Jessner s solution has been used alone for superficial peeling, or in combination with TCA 35% to achieve a medium-depth peel. Increasing the number of coats applied to the treated area increases the depth and reaction induced by the Jessner s peel. These peels are well tolerated with minimal side effects in the author s practice. As with glycolic acid and salicylic acid peels, Jessner s peels are most commonly used as adjimctive therapy for moderate to severe facial dyschromias, acne, oily skin, texturally rough skin, fine wrinkles, and pseudofolliculitis barbae.

Changes in skin texture, pigmentation, vascularity, and hair and nail appearance are indicative of possible toxic exposures. 

Topical applications of retinoic acid derivatives reduce the visible signs of aging and of photodamage,266 though there is little correlation between the histologic changes and the clinical appearance of the skin. Initial improvement in fine wrinkling and skin texture correlates with the deposition of HA in the epidermis. 

A relatively old publication attempted to link skin texture to the measurement of /%. Authors found fairly good correlation between the smoothness of chamois leather, as perceived by experts, and the inverse of /u-k.8 This in vitro result was, however, not confirmed in vivo by Prall who found other types of correlations.9 On the other hand, it has been shown that 1 //u-k correlates very well with the slippery effect of oils. Such results reveal the complexity of the quality of smoothness smoothness of skin and smoothness perceived when applying a cosmetic product to the skin correspond to two different sensations.

Comedonal acne and acne rosacea respond well to tretinoin. In fact, the anti-aging effect of tretinoin was first observed in patients being treated with tretinoin for comedonal acne their skin texture and skin tone were gradually seen to improve. 

LameUar Injection Molding Injection molding of individual fliermoplastics or their blends, e.g., with liquid-erystal polymers, that produees a lamellar (platelike crys-talUte) skin texture of the molding for decorative purposes or enhanced surface properties.

We usually utilize bio-revitalization before combined peeling with 25% salicylic acid followed by 25% TCA in patients with photoaging of the face, hands, neck, or decolt6 who complain of skin dryness and hyperpigmentation. Combining the two procedures enhances results of treatments as bio-revitalization improves skin brightness and moisturization and chemical peeling improves skin texture and color (Fig. 10.1a, b, c). 

These are mainly facial-cleansing products. Use of facial-cleansing products is not a new phenomenon, having been used by women for centuries. It was very common in Indian culture to apply an aqueous paste of turmeric and mustard seed powder to the face and body of brides before marriage to make the skin soft and clean. There are different herbal and natural paste formulations from Ayurvedic and Unani medicines, which are used to improve the facial or body skin texture. Before the development of synthetic surfactants, soap was the main product used as facial cleanser. Owing to superior mildness, products based on synthetic surfactants are preferred over soap. 

Shagreen skin is another chronic reaction to pitch products. This entity coined by Prosser White is characterized by keratosis, pigmentation, telangiectasia, superficial capillary dilatation, and alteration of skin texture with areas of hypertrophy and atrophy. Superficial fissuring and possibly papillomata may also occur. This condition which mainly affects the dorsal forearms, hands, face, and neck generally appears after 10 years or more of CTP exposure (Ross 1948). This condition is usually asymptomatic, and treatment is essentially preventive as the changes are permanent. 

A 3D face model includes two constituents a face shape model (represented by a 3D geometric mesh) and a skin texture model (generated from 2D images).
