Smooth, plump and a natural glow – young, healthy skin is usually blessed with a flawless complexion. Not only are sebum production and moisture levels in perfect balance, but the skin’s regeneration processes all work at maximum potential. To cut a long story short: The skin is resilient and well able to defend itself against external aggressors and oxidative stress. BUT: When environmental stress becomes too much, the skin’s own defense system might not be strong enough to handle it. This can lead to premature aging and the appearance of facial flaws and blemishes.
