Your 40s are when skin changes become more noticeable—fine lines turn into deeper wrinkles, collagen production slows, and skin elasticity decreases. You might notice more volume loss in the cheeks, nasolabial folds, and jawline, leading to a tired or sagging appearance. Sun damage from earlier years can result in uneven skin tone, dark spots, and a rougher texture. Hormonal changes may also cause increased dryness, acne flare-ups, or sensitivity. Fortunately, advanced aesthetic treatments can help restore a youthful, refreshed look.
