Oman today_ One of the side effects of using foundation is clogged pores, which can lead to acne on the face. Aging and wrinkling of the skin is another side effect of using foundation for a long time. In fact, the best practice is to use foundation temporarily and for a short duration. A bitter truth about foundation is that the longer the product lasts, the heavier it is. These heavy substances, if left on the skin for an extended period, prevent it from breathing naturally. Skin that cannot breathe well throughout the day gradually suffers from oxygen deficiency. This lack of oxygen in the skin leads to the breakdown and depletion of collagen. All these factors combine to prevent the skin from properly undergoing its natural regeneration process. A deficiency in the skin’s repair and regeneration functions leads to wrinkling. If you want to have fresh and youthful skin, minimize the use of foundation and avoid long-lasting foundations unless it’s an emergency. Other side effects of using foundation include skin shine, dryness, and spotting.
