Spots be gone!

5 stars out of a maximum of 5

I am 37, Caucasian, fair complexion, sensitive skin. I have used prescription retinoids 3-4 days a week for approximately 18 months. They've helped significantly with wrinkles and overall texture. However, I still had sunspots. I was perplexed and thought the retinoids should help. A good friend who uses this product religiously told me to try it as Vitamin C helps with discoloration more so than retinoids. Who knew?! I purchased this product for the first time in June 2020. I've used it 3-5 days a week for the last 90 days. I am very pleased with the sunspots that have faded and others have completely disappeared! I will say the serum is thick so it can cause breakouts if you're acne prone. I recommend some type of exfoliating treatment to keep pores clear.

Major Irritation and Breakout

1 stars out of a maximum of 5

After using this for a few weeks it caused major itching, irritation and scarring breakouts on my neck, around my mouth and on my hands and forearms. Spending another small fortune on products to correct the skin issues this product caused.

Best Vitamin C

5 stars out of a maximum of 5

I was told to try Obagi vitamin C by a friend and started off with the 15%. After a few months I decided to move to the 20%, because I have some melasma on my forehead. I love both the 15% and 20% and have noticed a HUGE difference in my melasma. It's much lighter. Obsessed and will never go without this product!

Magic serum

5 stars out of a maximum of 5

This is an amazing product. I noticed the brown spots on my face begin to fade within days of use. My skin is looking smoother and radiant. It is well worth the price and will remain in my regimen.

Best Vit C - a little goes a long way

5 stars out of a maximum of 5

My favorite Vit C serum yet. Skin looks and feels better within a week. Lasting better than other products and provides excellent coverage with just a few drops.

Great benefits

5 stars out of a maximum of 5

Great product that has shown benefits for the last 5 months of use. Only disappointment is how quickly it goes using 4 drops once a day.
