Hello, Probable causes of your condition are tenia cruris, keratosis pilaris, atopic dermatitis, folliculitis, milia, or pityriasis rubra pilaris. As your condition has been for years without notable symptoms most probably yours is keratosis pilaris. Many treatment options and skin care recipes are available for treating keratosis pilaris. As a general rule, treatment needs to be continuous. General measures to prevent excessive skin dryness, such as using mild soap-less cleansers (eg, Dove, Cetaphil), are recommended, and lubrication is the mainstay of treatment for nearly all cases. For mild cases, Cetaphil lotion will help. The affected area may be washed once or twice a day with a gentle cleanser such as Dove. Additional therapeutic options for more involved cases of keratosis pilaris include lactic acid lotions (AmLactin, Lac-Hydrin), alpha hydroxy acid lotions (glycolic body lotions), urea cream (Carmol 10, Carmol 20, Carmol 40, Urix 40), salicylic acid (Salex lotion), and topical steroid creams (triamcinolone 0.1%, Locoid Lipocream), azelaic acid, [14] retinoic acid products such as tretinoin (Retin-A), tazarotene (Tazorac), and adapalene (Differin) Lotions should be gently massaged into the affected area 2-3 times a day. Persistent skin discoloration, termed hyperpigmentation, may be treated with fading creams such as hydroquinone 4%, kojic acid, and azelaic acid 15-20%. If your lesions won t fade away even after above therapy for 2 weeks, you need to consult a dermatologist. Take care. Hope I have answered your question. Let me know if I can assist you further.
