Skincare is the act of tending to the largest organ of the body — your skin. Some view skincare with a medical lens, while others look to it for purely cosmetic reasons. Every person's skin reacts to the environment and ingredients differently, which means there will never be a one-size-fits-all method to skincare. Skincare can embody the full range of approaches, from a daily regimen consisting of topical creams and serums to more procedural treatments like microneedling and filler injections. The world of skincare is constantly advancing as we discover new strategies and ingredients for fighting acne, aging, sun exposure, and other threats to the integrity of one's skin.
