Irritation is normal…but that doesn’t mean it sucks any less. We get it – no one wants to have red, dry, or peeling skin. However, these side effects (in moderation) are actually part of your skin adjusting to the retinol product. If the irritation continues or causes a lot of discomfort, it’s probably best to stop using the retinol and consult a dermatologist. For most of us, however – the irritation will subside after a week or two, once your skin has built a resistance and tolerance to the chemical formula.
