Best Growth Factor Serum In The Market!

4/17/2017 by Eric

Osmosis Stemfactor has transformed my skin! It cleared it in 2 weeks. I no longer have any wrinkles and my face is youthful and glowing. All of the Osmosis products are fantastic because they PENETRATE and get into the dermis and work their magic. This is the best skin care line available on the market. There is no need for harsh chemical peels or prescription strength retinoids that cause inflammation. And inflammation leads to aging. Take a gentler approach to anti-aging with the outstanding Osmosis Skin Care Line, You will be very happy you did! A++++

I've been an esthetician since 2002, and Osmosis is the BEST! Truly results-oriented products that absorb and transform skin to its absolute best potential. I've been using the line for 2 years, and Stem Factor for a year, it is amazing. I had a hypo-pigmentation spot caused by a glycolic/retinol peel from years prior and was very upset about it. After a few months of Stem Factor and Rescue together on that area, my melanin was restored!! I couldn't believe it, since that's not supposed to happen, but for me I had a hunch and tried that combo and it worked. It has a nice consistency and makes my skin feel velvety smooth.

I have been using StemFactor for 6 weeks now and the clarity in my skin is truly amazing. There has been a significant improvement in the texture of my skin as well as the feel. I love it and won't be going back... it's onwards and upwards with StemFactor.
