Prescribed by my derm when I did a chemical peel. It used to come in a pot formula but they have now packaged it into a squeeze tube version which I prefer as its more convenient. Its more of a light cream than a really lightweight moisturizer so I wouldn't recommend for oily skin. Works good if you are on Differin and the skin feels a little dry. Purchasing was quite troublesome though- it is only available in selected hospitals or skin clinics. Have repurchased it once before but am unsure if I will repurchase again as I think its not too value for money, a small tube of 30g for USD12. Produced in the USA.
