Internal and external causes: Skin aging process, hormonal problems, environmental climate, smoking.
Preventative steps to take: Avoid touching your face; wear sunscreen every day, even on cloudy days; exfoliate your skin once a week with a gentle chemical exfoliant; wash your face every day with a gentle cleanser; never skip out on moisturizing (ideally use two different moisturizers: a creamy one for the drier areas and a lighter water-based one for the oily part); drink at least 1.5 liters of water a day; avoid products that are too abrasive.
How to reduce or eliminate: Use products containing active ingredients with sebum-regulating (salicylic acid, azelaic acid, etc.), moisturizing/moisturizing (hyaluronic acid, etc.), exfoliating (lactic acid, gluconolactone, glycolic acid, etc.), antioxidant (ferulic acid, vitamin C, vitamin E, resveratrol, etc.) and emollient (ceramides, squalane, fatty acids, fatty alcohols, etc.) properties. Avoid elements that are too aggressive for the skin; add a tonic lotion to your beauty routine to rebalance the pH.
Definition: A type of skin characterized by an oily part in the T-zone (forehead, nose, chin) with dilated pores and possible imperfections (blackheads, pimples), and another normal to dry part generally in the cheeks, temples and around the eyes. It may be accompanied by redness, occasional tightness and a rough skin texture. It thus represents a mixture of two skin types. The oily area is explained by a high quantity of sebum, while the dry areas (temples, cheeks) result from a lack of sebum and a deficiency in lipids (essential fatty acids).
