Tretinoin prescription

The choice of one or another of these molecules depends on the condition of the patient s skin. Tretinoin is not used if the patient has many telangiectasias AHAs are avoided if the skin is very thin. Conversely, the two products can be mixed in the same prescription, in variable concentrations, depending on the skin type and the desired effect. The concentration of tretinoin would be increased to stimulate reepithelialization the concentration of glycolic acid would be increased to improve and even out transcorneal penetration. 

If this dose is well tolerated, it is possible to go immediately or gradually to a concentration of 0.05%. This concentration is common in proprietary medicines, but if prescription medicines are preferred, it is possible to prescribe 0.05% tretinoin in the following formulation ... 

Tretinoin cream should be kept out of direct sunlight and away from heat sources, to which it is sensitive. In spite of these precautions, it gradually loses its efficacy and it is recommended that the prescription be renewed every 3 months. Tretinoin is sensitive to oxidation, heat and ultraviolet light the refrigerator (4 C) seems to be the best place to store this cream. The by-products of degradation turn the cream a yellowish color, in which case it should no longer be used. 

In addition to the 16 sunscreens approved in the United States, there are 2 non-sun-screen topical agents that are approved for the treatment of conditions related to photo-induced skin damage. These are tretinoin and hydroquinone. Both are prescription products. Tretinoin is approved as an adjunctive treatment for "mitigation of fine wrinkles, mottled hyperpigmentation, and tactile roughness of facial skin." Hydroquinone has been marketed for decades for bleaching of hy-perpigmented skin conditions.
