subject: Photoaging diagnosis and treatment [print this page] Photoaging diagnosis and treatment
Photoaging refers to those changes in the skin that are induced by repeated exposure to sun. It is also termed premature aging' or dermatoheliosis'. It is characterized by coarsness, wrinkling, mottled pigmentation, laxity, telangiectasia, purpura, easy bruising, atrophy, and pseudoscars. Ultimately premalignant and malignant neoplasms may develop on the exposed areas. The principal premalignant lesion is actinic or solar keratosis. 25 percent of patients with multiple actinic keratosis develop squamous cell carcinoma in one or more of the lesions. Basal cell carcinoma and melanoma also occur with greater frequency in sun damaged skin. Ultraviolet portion of sunlight, particularly UVB is implicated in photoaging and photocargenosis. UVA and infrared energy may also contribute.
Diagnosis It is clinical. It may be supplemented histopathological examination that reveals the following; (1) Thinning of the epidermis, (2) effacement of the rete ridges, (3) abnormal keratinocytes in a disorderly arrangement, (4) impairment of melanin transfer from melanocytes to keratinocytes, (5) progressive degenerative changes incollagen and its replacement by elastic fibrils and finally homogenization and elastosis of the dermis, and (6) vascular dilatation and ectatic vessels.
Treatment The patient should avoid further exposure to sunlight. The premalignant lesions may be treated with topical fluorouracil. Lesions that persist after traetment with flurouracil are probably invasive. They should be biopsied and treated according to the nature and staging of the malignancy.
Unani treatment
Grape (Vitis vinifera): Grape seeds contain high levels of proanthocyanidins, antioxidants up to fifty times more powerful than vitamins E or C. Studies show that grape seed extracts applied to the skin can bond with collagen, boosting skin's elasticity and texture and reducing the signs of aging.
Pineapple (Ananas comosus): Pineapples contain alpha-hydroxy acids and other natural fruit acids, which are used topically and have been shown in numerous studies to be an effective weapon against aging. You'll also find them in mango (Mangifera indica), papaya (Carica papaya), and passion fruit (Passiflora edulis).
Pomegranate (Punica granatum): Pomegranate, which is high in antioxidants, can help repair aging skin. Extracts of both the peel and seed (oil) have shown the ability to inhibit age-related collagen loss and speed the production of new supplies.
Rose (Rosa canina, R. damascena): Rose is rich in antioxidants and has one of the highest concentrations of vitamin C in the plant world. Rose oil and rose hips (the fruits left behind after the flower dies) can prevent UV-induced skin damage and act as a natural sunscreen.
