BRIGHTEN & TIGHTEN Biolumin C Serum from Dermalogica; a high-performance Vitamin C-infused serum that work’s with skin’s own defenses to brighten and firm the complexion. As I actually use retinol most evenings, this is something I like to apply in the morning after cleansing. With Vitamin C serums,you want to be looking for a potency if 10-15%. I have searched dermalogica a website and not yet come across this information however, I have noticed this serum contains lactic Acid (among other fab ingredients) The moisturising serum works to accelerate cell turnover, neutralise skin after oxidation and defend against harmful aggressors. Although I have only been using this for about a week I can already see how much brighter my skin in. I will of course be using for around 6 weeks before posting a full review on my blog. So far, so good though. . http://liketk.it/2B3jQ . liketkit @liketoknow.it LTKbeauty LTKeurope LTKhome LTKtravel LTKunder100 LTKunder50 LTKworkwear LTKspring @liketoknow.it.europe
