Great addition to my skin care routine

5 stars out of a maximum of 5

I have been using this now for 4 months, almost daily since purchasing. This was suggested to me by a skin care specialist, and my goodness I do NOT regret adding this to my regimen. Although my skin is slightly on the sensitive side, this did not inflame or bother it any more than usual. I use this after I cleanse, and before I use my Tretinoin cream at night, then follow it up by using the Obagi hydrate moisturizer. I wait a few minutes before applying each product, like my skin care specialist suggested. I have not tried using this in the AM. I chose to only use this in the PM, but I understand that the AM is also suggested. Before bed is just my preference, and in 4 months I can say my skin is pretty radiant and less splotchy from adding this in. I used to just cleanse, slap on some tretinoin cream, and call it a night. I've seen much better results from the addition of this C serum. It is pretty pricey, however, I wait till Obagi has their discounts on the Dermstore site. Also note, I am still working on my first bottle... this lasts quite a bit, which is a plus!

Great product!

5 stars out of a maximum of 5

I have dry, sensitive, fair skin with hyperpigmentation and this product works wonders! I can see a difference within days of use. It is a bit pricey, but worth it! My dark spots fade, wrinkles are less noticeable, and skin is firmer.

Great, great product but...

5 stars out of a maximum of 5

Amazing. The fastest vitamin c serum i've used so far. My acne PIH improves drastically even after one night of use. I have learned to spot treat with this particular serum because of my acne prone skin and because this is an oily real deal vitamin c serum. I will get clogged pores or small zits from using this. I try to keep it just on my spots and I do really well with that. I use this along with derma rolling and over some time you can really fade your marks on your own.

Liquid Gold

5 stars out of a maximum of 5

I love this product. It is one of the best serums I have ever used. Goes onto my face smoothly and doesn't dry me out. Works well under my tinted moisturizer. I am a 44 year old that feels like the 20% is perfect for my young aging skin.

First thing I put on in the morning

5 stars out of a maximum of 5

I put this on 1st and all other products go on smoothly after it. It really brightens my face. A little expensive but a few drops go a long way. The bottle lasts me a long time. The only thing I don't like is that it has a dropper. I prefer pump products
