As seen in British Vogue magazine, this serum is number one for giving you the radiant skin complexion that you long for. It uses peptides to reduce the appearance of fine lines and wrinkles. As you age the natural collagen in your skin starts to diminish and this process causes skin to get thinner and more prone to wrinkles. The peptides used in this serum put the collagen back into your skin causing it to tighten and appear more plump and firm. The glow effect from using this product comes mainly from bear-berry extract which is a natural skin lightener that reduces melanin formation. This process helps to reduce the appearance of dark spots and skin discoloration causing skin to have an overall youthful, radiant glow.
