Acne is always hormonal, i.e. pregnancy, the pill, menopause, or even PCOS. The first thing to do is switch to oil-free or noncomedogenic products. Avoid anything that contains lanolin, mineral oil, or petrolatum. Don’t use pressed powders or pancake or powder foundation, because they contain oil. And never cleanse with harsh soaps that will dry out your skin, because they don’t help clear up the acne, and you wind up using too much moisturiser to counteract the dryness.
Try products that remove blocked pores and excess oil production. We have developed a Clear Skin program especially for this concern. They contain glycolic and salicylic acid, all of which can help; but again, don’t overuse them, because they’ll dry you out.
