PLEASE REVIEW — FORMULA CHANGED!!!
I wish I would’ve posted a review PRIOR to the formula changing but just know that I LOVED this serum. I’ve struggled with hormonal acne (PCOS) and eczema for as long as I can remember. Finally, last summer my dermatologist put me on (3) different RX including Spironolactone and Accutane. I was so tired so I stopped everything except for CeraVe cleanser, retinol (Tretinoin) and CeraVe healing ointment. My made up skin routine was working until I used too much Tretinoin and burned my face. I had read great reviews about this product so I thought, I might as well try it — and IT WORKED! I’ve been using this product for almost a year and I loved it. However, 3 weeks ago when I ordered it, I noticed the bottle had a green tint. I could tell after one use that the feel of the serum was different, more watery, not as thick as it used to be. The smell was also different. Still, I kept using it for nearly 2 weeks and I experienced 2 breakouts! Sure enough, I stopped the product and within a few days, my skin was back to normal. I am very upset because as someone who has extremely sensitive skin, this worked but unfortunately, the new formula isn’t for me.

Great lotion for very dry skin
Style: Updated Formula
I had a laser done on my face and the products they gave me weren't working. This came highly recommended so I gave it a try. I'm very glad I did! It moisturized my face really well without appearing greasy.
I used the rest when my face got dry from winter (in th midwest).
Felt very rich and smooth. Medium thickness.
