    Overall good product.

    [This review was collected as part of a promotion.] This was great! Helped with my skin tone and brightness very well. I hadn’t tried this type of serum before and was happy with it. The only thing that wasn’t as consistent was a bit of dryness at the end of the day. Overall good.

    Nice product, just not for me.

    [This review was collected as part of a promotion.] I love the brand, but this product just didn’t do much for my skin. That’s not a bad thing, as it didn’t break me out or irritate my skin. It goes on easily and plays well with other products. I know it has some powerhouse ingredients, but it just didn’t change anything about my skin! A little does go a long way. So, even though this didn’t really work for me, I know it will for others.

    I received my first bottle

    [This review was collected as part of a promotion.] I received my first bottle of this product as a gift and I have since repurchased several times. I am obsessed. I use it every day, twice a day after cleanser. It makes my skin glow. It looks clear with a slightly thicker than water texture. When I skip a day it stings slightly when I put it on, but not in a painful way, just in a "I can feel it working" way. When I am using it consistently there is no sting at all. It makes my skin look and feel so good. Highly recommend.

    Hydrated, plump and smooth skin

    [This review was collected as part of a promotion.] All in all the packaging is efficient for dispensing the product. The consistency is nice, not tacky or sticky. Glides onto the skin and absorbs quickly. A solid price for the ingredients. I saw the benefits when layering with the rest of my skincare routine.

    Not for me!

    [This review was collected as part of a promotion.] So this brand is well known i am quite aware! However it was a no go for me! I tried it multiple times hoping I would have different results but it was always the same. My skin is pretty sensitive and this dried my skin out pretty bad! This happened different times so it wasn't a fluke! This is just not for me!

    [This review was collected as part of a promotion.] I’ve been really impressed with this skin booster. The texture is very watery and lightweight, so it absorbs almost instantly without feeling sticky or heavy. As soon as I apply it, my skin feels fresh, soft, and hydrated. Even when I use just a cleanser followed by this serum, my skin looks noticeably brighter and feels smoother.
