How To Use La Roche Posay Effaclar Duo (+):

La roche posay Effaclar duo is a gentle moisturiser that is suitable for daily use both day and night (avoid eye contour area). A common mistake that people with oily, blemish-skin types is that they choose to avoid wearing moisturiser to avoid ‘clogging up the skin’. However, the result of not moisturising your skin daily, is that it can become dehydrated even if your skin is oily (read more). Signs of dehydrated skin are tightness, flakiness, redness, inflammation, blackheads, and breakouts. Effaclar duo is a moisturiser that won’t clog your pores but will still keep your skin nourished.
