Unfortunately there is nothing over the counter that matches the efficacy of Tazorac. Tazorac is the name brand of a prescription retinoid. Retinoids are a derivative of Vitamin A that have proven to benefit skin in such ways as clearing pores, boosting collagen, and increasing cell turnover. You can find retinoids in various forms and strengths, in both prescription and non-prescription topical products. Over the counter products are made to be safe for mass consumption, and will not have the same percentage of active ingredients as prescription or pharmaceutical grade products (often referred to as “cosmeceuticals”). Often times the majority components of over the counter products include preservatives, fragrance, and other non-active ingredients. These kinds of products will also typically only penetrate the most superficial layers of the skin, and will therefore provide minor improvement. If cost is a concern, ask your Dermatologist to prescribe a generic tretinoin, or look into purchasing a pharmaceutical grade product from a professional. Some pharmaceutical grade products may be more pricey than over the counter products, but because they are much more potent, less of the product is needed to be effective. In the long run, it is likely you would spend more purchasing an abundance of mildly effective over the counter products, than a few highly effective professional grade ones. Quality over quantity! Consult with a board certified Dermatologist to see what may be the best option for you.
