An example of a routine, for sensitive, slightly dehydrated, acne-prone skin. - micellar water Nivea Micellair Expert Make-Up Remover (evening)/Cerave Micellar Cleansing Water (day) - Cerave hydrating cleanser gel (evening) - Avene thermal water -Niod Hyaluronic acid complex -The Ordinary Salicylic acid 2% -La Roche-Posay Toleriane -La Roche-Posay Antishine (fragrance-free) (day) As you can see, it does not receive acids and strong actives, for several reasons: If we don't have a correct basic routine, we risk doing more harm than good. In vain we use acids for the imperfections caused by acne, sebum and UV radiation, if we do not devote the same attention to the primary needs of the skin: cleaning, hydration and especially sun protection. We introduce only one active ingredient, salicylic acid, because salicylic acid is not so photosensitizing and is best suited for oily, mixed, acne-prone skin, with black and white dots, but also for skin with seborrheic dermatitis, mild rosacea or melasma. We apply less often, a smaller amount, observe, wait and increase the frequency only if necessary!
