It is best to use products that are hypoallergenic, dermatologically tested and non-comedogenic alongside Tretinoin. This is particularly important to prevent further inflammation and irritation as well as increase moisture in the skin. Ensure that products are fragrance-free as well as free from benzoyl peroxide or alcohol as these will exacerbate dry skin conditions. Ingredients such as the vitamins niacinamide, panthenol and tocopheryl acetate can complement Tretinoin and provide improved results from the treatment.
