The real reason it interested me was it aids in improving the translucency of skin. I combat dullness daily and this offers a way to get brighter skin while easing dullness. It’s supposed to reduce freckles and dark spots with Vitamin C when used daily but I’ve been using it for several weeks and haven’t notice any lightening of my dark spots. The pink purple-ish shade will work best on those with yellow under tones as it reverses the appearance of that yellow and lends skin more of a brighter finish. It also contains an SPF 30 to protect skin and protect it from future damage and aging. It has a super light feel so it really isn’t uncomfortable in the least for wear under foundation. I personally wouldn’t wear it with out foundation or BB Cream because the brightening effect is a bit pasty for use on its own. The brightening/whitening effect is only during wear and doesn’t actually whiten skin. Applying too much can create a white cast so be aware should you try it and use a little bit.
