I have been using this product for about 2 weeks now and have not seen any results yet. I use it at night with my moisturizer and and in the morning with my sunscreen. I also mix it with the Philosophy Vitamin C Booster Powder. It says on the bottle to use 3-4 drops every time but I have been using it for only 2 weeks and I am already half way empty. Will I even get to see results before it runs out?

Holy grail to brighten oily skin. Love this lightweight serum. Weightless and soothing. Will rebuy again and again!

This stuff is HG status for me. Never in my life have I had my skin so smooth and clear. It's a little pricey but lasts a while and is worth it. My skintone is now even, smooth, and my pores... what pores? I mix this with their Vitamin C powder for extra benefits for my skin. Can't say enough good things about this product.

I got this as part of the Makeup Optional kit, and like the rest of the products, it's left me fairly underwhelmed. It feels quite nice when you put it on, I guess it's hydrating enough, but it just doesn't seem to do a lot for my skin. I used up nearly the whole bottle and I can't say that my skin looks any better than when I started using it, and if anything it has caused me to break out a little. For the price, I don't think this is anything special.

I have very dry sensitive acne prone skin...I've been looking for the perfect products for my skin for a very long time. Thick moisturizes break my face out but the serum is amazing! Gets tacky for a sec before it completely sets on the skin then it's like your own skin. I still use with just a touch of hope in a jar when I feel extra dry. On my third bottle and my used to be crap skin is beautiful, supple, and super soft. Love it!!! Ps. 1 week isn't long enough to see dramatic results. It's a slow process but worth the wait. My skin has NEVER looked better!

I didn't react badly to it, the smell wasn't offensive to me, I just didn't see any benefits. My skin didn't look radically better. I used it with hope in a jar, purity cleanser, and the eye cream, so I used the entire product line as recommended. I can't say it made my skin look any better or worse than the Oil of Olay Regenerist products I've been using. I didn't break out, there's no reason I can't use it, I just don't see any reason to use it when there are much cheaper alternatives.

I was excited to get this product and really wanted to like it. I have combination medium/olive toned skin with old acne post inflammatory hyperpigmentation marks that I wanted to fade.The first week I noticed some breakout and thought it was just purging or my skin getting used to it. I kept using it and kept breaking out, a month later and a few new acne marks left over on my skin and I was done. Will not buy again. Wish I stopped after that first week.

I've already on my 3rd bottle and has been a staple since for some reason this serum consistency takes well with my skin. I have added the Vitamin C Booster powder and have noticed my cheeks appear better.

This came as part of the makeup optional kit. It made my skin red and itchy, have to return the kit as the other products are burning my face.
Horrible product. I purchased the kit for dry sensitive skin-biggest scam

I got this serum as part of the Philosophy "Make-up Optional Set" The only thing in that entire set that I like was the Purity face wash and the Hope in a Jar moisturizer was pretty nice as well. Everything else was so-so, but this was the one thing that was a huge disappointment. You would think with the $40+ price tag that you would at least see minimal results, but nothing. I could barely stand the smell. I'm not the type of person that is sensitive to smells either, but this was so bad that I literally had to plug my nose every day when I put it on, a few times I thought I was going to start dry heaving it was that bad. I ended up using it for about 5 weeks and got so sick of it doing absolutley NOTHING-that I ended up throwing it in the garbage where it belongs. Will NOT be repurchasing this disappointing product.
