Best part of my skin routine

I use Obagi Medial Professional-C Serum 20% daily. It is the best part of my skin routine. It keeps my skin plump and bright. If you have never used the 20% strength, I recommend you start with the 10% and then work up to 20%. This is a truly great product that I will not go without.

Favorite Vitamin C

I love this formulation. The 20% is strong. If you have dry or sensitive skin you may want to start at a lower concentration.

2nd time purchasing!

the 20% is amazing and I will continue to purchase. A bottle lasts about 6 or 7 months which makes the price not feel so bad.

Best Vitamin C Ever

This is SO GOOD. Hydrates while giving a great glow. I have oily, acne prone skin and does not make me break out nor cause more oiliness. You do not need a lot at all. 4 drops covers my whole face and neck.

Morning staple

I have been using this every morning for 2+ years. Have tried other vit C in the past, but this has been my favorite so far.
