"I started using Osmosis about two weeks ago and only off and on. I had several skin tags on my face, which a doctor want to charge 100 dollars per tag to remove. The StemFactor dried them up and I have been removing them when washing. Unbelievable. I thought I had to live with and the best part, no hyperpigmentation. Thanks!" ~ B Andrews

Esthetician Marianne Kehoe, has worked with thousands of clients and numerous products for more than 20 years. "Between Catalyst and StemFactor, the results I’m seeing in my practice are phenomenal, repeatedly,” according to Kehoe, “including with post-operative scars and people who have been exposed to the California sun for years."

"Over the past month I have noticed a significant improvement in my skin through using Osmosis skincare. I began with a starter pack then introduced Stem Factor - this has resulted in a huge difference to both the acne prone areas as well as contributing to the overall glow of my skin. I have had problems with my skin for a number of years and in particular Osmosis Stem Factor is the only product I've found that continues to improve skin appearance." ~ Emma

I love this product! My skin suffers from monthly hormonal breakouts but since using this product, my skin is so clear. It smooths out my fine lines and definitely gives it a glow. I didn't expect it to help with breakouts but it's a miracle worker!

Best Growth Factor Serum In The Market!

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++++

Best Product

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.
