More skincare advice from Dr Sam Bunting

@drsamskincare Vitamin C works hard for your skin.  We know it’s essential because scurvy due to vitamin C deficiency causes poor wound healing - that’s why it’s vital if you want strong, functional collagen.  But it also helps deliver a bright, even skin-tone because it suppresses the rate-limiting enzyme tyrosinase.  Finally, it helps prevent premature ageing through its ability to neutralise harmful free radicals and minimise oxidative stress, which triggers a cascade of events from increased collagen breakdown and damaged elastin.  Adopt an inside-out approach. Make sure you’re getting plenty of vitamin C from your diet - think citrus fruits, kiwis (my favourite) and berries. And top up with the form of topical vitamin C that’s right for your skin.  #vitaminc #collagen ♬ original sound - Dr Sam’s Skincare
