There are a lot of skincare benefits associated with working out. “Exercise helps maintain healthy levels of the stress-related hormone cortisol,” esthetician and founder of Stacked Skincare Kerry Benjamin explains. “A high cortisol level could lead to breakouts or cause the collagen in your skin to break down, which can increase wrinkles and sagging. A good workout will actually help your body in the production of collagen, and this keeps your skin firm and supple.” She adds that aerobic exercise gives your skin a hit of oxygenated blood, which is critical for glowy skin.
