It Works...THE BEST...I'm not sure what it is about this product, but I was given an acne prescription by my actual doctor to help control hormonal acne as well as cystic acne and that acne prescription never worked as good at this product does....I used this one a few zits I had, two new ones and two almost healed ones, after I washed my face with the Neogen green tea cleanser and I used the Korres Wild Rose moisturizer after this spot treatment, and so far I love it.
"Retinoids work over time by continuously increasing cell turnover which in turn helps fade hyperpigmentation," says Dr. Idriss. Dr. Shah agrees, noting that Retin-A helps with acne marks by causing your skin cells to "divide more rapidly and pushing out cells with discolored pigments." Since retinoids make your skin super-sensitive to the sun, it's best to not only wear SPF, but to also apply a treatment like RoC Retinol Correxion Sensitive Night Cream before you go to bed.
Drugs: Some medications may cause or worsen acne, such as those containing iodides, bromides, or oral or injected steroids (either the medically prescribed prednisone [Deltasone, Orasone, Prednicen-M, Liquid Pred] or the steroids that bodybuilders or athletes sometimes take). Other drugs that can cause or aggravate acne are anticonvulsant medications and lithium (Eskalith, Lithobid). Most cases of acne, however, are not drug related.
