Objectives: Skin represent both the largest organ of the body (one-sixth of body weight) and the first line of defense against aggressions, and now is considered an endocrine gland which produces hormones and neurotransmitters. Also, skin health and skin influence directly self-esteem and mental status, social interactions and
quality of life.
Introduction: The face is the primary source of information in social perception and serves a key role in social perception, affecting people’s judgments of everything from trustworthiness and aggressiveness to competence and likeability in as little as 100 ms. The distribution of pigment color (blood and melanin) in the skin can affect the apparent health, age and attractiveness of human faces. Facial appearance, or perceived age, is composed of different facial features, including skin wrinkling, lip size, pigmented spots, skin texture, and sun damage.
Materials / method: 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 main signs of aging can be classified into four main categories of wrinkles/texture, lack of firmness, vascular disorders, and pigmentation heterogeneities.
Results: Visible skin color distribution appears to have major influence on the perception of female facial age and judgments of attractiveness, health, and youth, and the dynamic range of the estimated ages indicates that visible facial color distribution can account for up to 20 years of apparent age, independent of facial form and skin surface topography.
Hyperpigmentation (postinflammatory dark marks, melasma, or solar lentigines), increases the perception of an aged appearance to a greater degree than wrinkles.
Conclusion: The dangers associated with treatment of pigmented lesions are connected with the person which perform the treatment (respectively non medical peoples) and with specific side effects of EBD treatments, erythema and skin burns, infections and hyperpigmentation, and in the worst case scenario even with melanoma. Skin color homogeneity, driven by melanin and haemoglobin distribution, influences perception of age, health and attractiveness, și and accurate diagnosis of pigmented lesions is mandatory before laser treatment. For some pigmented lesions, laser treatment may be the only treatment.
