Tretinon n is used to treat acne or other skin diseases as determined by your doctor. It works partly by keeping skin pores clear. One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by the damaging rays of the sun.Derived from vitamin A, retinoids — such as tretinoin (Retin-A, Renova, Avita) — that you apply to your skin may improve the appearance of stretch marks less than a few months old. Tretinoin, when it works, helps to rebuild a protein in the skin called collagen, making the stretch marks look more like your normal skin. #tretinon #acnevulgaris #trustyorganics #trustynaturals #trustyherbalclinic
