I had two dark spots on mu upper lip. Didn't see results right away it took about 3 months for me but I no longer have them dark spots. Worth the price & wait. Now I'm wondering if it will work for my armpits.

I'm not sure this is doing anything for my skin yet. I've been using for about 6 weeks and haven't seen any results. The smell is not that great - sort of smokey but goes away after a bit.

After receiving a sample of this serum and feeling pretty optimistic, I ordered a full size product.  The serum was a bit sticky and didn’t end up layering well with my other products.  I do think that it might have lightened some dark spots though!

I stumbled upon this product this past year. I have never received so many compliments on my skin (clarity of complexion and dewy glow)! I started noticing a decrease in sun spots after about 3wks of use, clarity in skin tone after 2wks and the dewy glow look gives the appearance of being refreshed (Turning 40yrs in 1 wk, 2 kids under 6 and work in a hospital full time). This is my first review ever of a product and I felt it was necessary! Highly recommend as well as any Dr Dennis Gross products! 

I am a 67 yo dude loving laser & Botox. Love excellent skin care products such as this! It contains everything I could possibly want in one serum. Look at those crazy ingredients and you'll see why this is clearly a keeper and my new fave. Results: skin brightening and even tone, exfoliation, hydration, and healthy revitalized skin. Ferulic, Kojic, Hyaluronic, Ascorbic, Lactic acids just to name a few... A++

I had 2 dark spots on my upper lip. They were pretty dark. I was trying for a year to find something that worked well I found this and it faded them completely. I only needed one bottle.

While this product is wonderful for fading dark spots, the packaging is just awful. It oxodized in under 6 months and like other reviews on here my dropper was faulty. So bummed because I really saw it working up until then!

I've just started using it few days ago. Can't tell what it does to my skin yet. But the first couple drops, they have deep orange color that stain your skin after applied then go away once rinsed off. Now the color is clear yellowish. Little tingling on the face for the first few seconds.

This is very powerful stuff. I would recommend that you not use any form of exfoliating granuals with this. I did and it really burned. No burn after I quit with exfoliating routine.

Used this for 3 weeks as directed and did not like it. I have oily skin and this product did not work for me. My skin felt sticky and shiny all day long. It also caused some pimples. I love other Dr. Dennis Gross products such as Alpha Beta Daily Peel, C+ Collagen Serum and Ferulic + Retinol overnight serum. These other products seem to do more for correcting dark spots.
