This is a must have in my am routine! I love how smoothly it goes on and the glow it gives! I’ve been using this for over 2 years now and would not be without it! 

I bought this because I have found other vitamins C serums can cause me to break out (e.g Sunday Riley CEO). I love lots of REN products and this is no exception. It brightens my skin without causing any negative effects and I would certainly repurchase

visible results after a few weeks, worth every penny

I use a vitamin C serum every day to even out my skin tone and give it a more even appearance, especially after spots. I also use a vitamin C mask from time to time. I also have very pale, almost white skin in winter and feel that vitamin C products make my skin glow. In fact, more than once I've had vitamin C products that my skin didn't tolerate, that didn't absorb. But this one absorbs wonderfully into the skin, a few drops are enough, the ingredients are largely natural and the glass bottle is still environmentally friendly: I like the REN philosophy, even if I don't like all REN products - but this serum is great!

A bit watery, which is not my preference, because it gets squirted everywhere out of the bottle.

This has been my go-to serum to brighten my dark spots and even the skin tone. Really start seeing a different after 2 weeks using it AM and PM. Love it!

I love this serum, have repurchased 3 times now. I’ve tried loads of different Vitamin C serums but this blend has been the only one to transform my skin. 

Now, this product is amazing, when used correctly and slowly. I made the mistake the first week of purchasing to immediately start using it every day, don’t do that! Slowly build up your tolerance and your skin will glow like no other! 

I've been using vitamin C serums for years now and don't like all of the ones on the market: Some have an oily consistency and don't want to be absorbed, others creep into the eyes and cause irritated eyes, and then there was once a serum in a sweet pineapple bottle that smelled absolutely no good and didn't want to be absorbed into the skin. But this serum smells good, has an eco-friendly glass bottle, absorbs super fast into the skin and leaves a velvety feeling and you really only need two or three droplets. And with regular use you really see results, the complexion looks clearer and finer and more even. Will be repurchased again.

This serum was raved about so wantdto try it. its a really nice antioxidnt serum. lightweight and hydrating, it didnt really target my hyperpigmentation as promised but it did give my skin a nice glow I would repurchase
