The main processes involved in skin aging are intrinsic and extrinsic. Apart from them, so called stochastic aging connotes cell damage caused by metabolic processes, free radicals and cosmic irradiation. The clinical expression of intrinsic aging include smooth, dry, and thinned skin with accentuated expression lines. It is inevitable and time dependent. Extrinsically aged skin shows signs of photodamage which include appearance of wrinkles, pigmented lesions, actinic keratoses and patchy hypopigmentations. Therapeutic modalities imply photoprotection with sunscreens that prevent sunburns and block ultraviolet irradiation. Other modalities include use of retinoids which regulate gene transcription with subsequent cellular differentiation and proliferation. The topical and peroral administration of »network antioxidants» such as vitamin E and C, coenzyme Q10, alpha-lipoic acid and glutathione, enhance antiaging effect. The other antioxidants such as green tea, dehydroepiandrosterone, melatonin, selenium and resveratrol, have also antiaging and anti-inflammatory effects. Topical bleaching agents such as hydroquinone, kojic acid and azelaic acid can reduce signs of aging. Studies confirm the efficacy of these topical agents in combination with superficial and/or medium depth or deep peeling agents for photodamaged skin treatment. Indications for type of chemical peels according to various clinical diagnosis are done, as well as advantages and disadvantages of differetn types of chemical peels.
