Photorejuvenation is a familiar item that can both whiten and rejuvenate skin and remove spots! But we often hear some rumors about photorejuvenation, and today we can help you shatter them! Rumor #1: Does photorejuvenation make the skin thinner? No. Many people think that photorejuvenation will burn the skin and destroy the fragile stratum corneum, just like a wall skin being chiseled off, the thinner it gets. Actually, no, intense pulsed light (photorejuvenation) activates fibroblasts in the skin, increasing the synthesis of collagen and elastin fibers and hyaluronic acid (hyaluronic acid). After these new collagen and elastin are rearranged, the skin will become more elastic, bright and firm, wrinkles will be reduced and pores will be refined. Therefore, instead of thinning the skin, laser cosmetic treatment will increase the thickness of the skin and make it firmer, more elastic, and transform it towards youthfulness. Rumor 2: Will photorejuvenation make the skin sensitive? No. Many people believe that photorejuvenation will lead to thinning of the skin and that without the protection of the “old skin”, the skin will become sensitive, heat- and wind-resistant, and sensitive to cosmetics. This is far from true. Although photorejuvenation accelerates the evaporation of water for a short period of time (7 days after the procedure) due to the photothermal effect, it promotes the exfoliation of the stratum corneum and sometimes the formation of small microscopic scabs. However, all the “damage” is manageable and will recover after 7 days. The newly healed skin is structurally intact (including the stratum corneum, which is subject to turnover even without treatment) and functionally healthy, so photorejuvenation does not make the skin sensitive. It is scientifically proven that intense pulsed light can repair inflamed skin, reduce the release of inflammatory mediators, remove excess redness and enhance the skin’s metabolism. So instead of making the skin more sensitive, intense pulsed light can treat the underlying conditions that cause skin sensitivity – seborrheic dermatitis, hormone dependent dermatitis, acne and rosacea, etc.
