Differin cream or gel is a topical medication that is commonly prescribed for acne. The active ingredient is adapalene. Differin is particularly good for comedonal acne and individuals with many blackheads and whiteheads will often benefit from this treatment. It can also help with inflammatory acne.
If acne is not improving with the topical differin, it is good to get the acne reassessed. Acne that is inflammatory will often benefit more with topical or oral antibiotics. Sometimes, the duration of use of the differin may not have been sufficient to see the effect as it does take regular application and some time for comedones to clear.
If the differin does not improve, often other topical medications may be added for a synergistic effect on the acne. In more severe cases, oral medications may be needed to control the acne. It is best to see your doctor or dermatologist for a reevaluation so that the appropriate treatment and medications can be prescribed.
