Wilma Schumann O2 Oxygen Blue

I started using this at the recommendation of my esthetician about a year ago and love it! I use this on its own as a moisturizer in the summer and layer it in the winter. Its super hydrating and it makes a huge difference with oil production over the course of the day. I use it daily and need to replace it one every 2.5 - 3 months. Definitely worth the price!

I’ve been using this serum for about 6 months or so under a facial sunscreen. Now on my 3rd bottle, I haven’t seen a significant pimple since starting. Leaves my skin feeling hydrated and youthful.

This product was recommended to me by my dermatologist. It is amazing. The amazon price is cheaper than in store but just the same. It was shipped very quickly and came with some amazing free samples which was a nice surprise. Would definitely recommend this product to anybody with dry dull or acne skin.

I absolutely LOVE this serum. My skin was immediately radiant and firmer after the first use. It is a keeper. It is non greasy and doesn't appear to clog the pores, either.

I love the product, but this the second time I have received an item purchased through Amazon and mailed in a flimsy envelope mailer w/no protective wrap on the product. Definitely NOT impressed with the shipping quality of this retailer.
