Products & Ingredients
In most cases, we use natural and bio-identical ingredients. Our clean, non-toxic formulas are holistic because they do not cause harm to the skin. Osmosis opted not to focus on organic products because we do not think they make lasting changes to the skin. Organic is really important in foods because of the properties of pesticides and additives otherwise present. In skincare, this is not an issue so there is no advantage. However, there is a distinct disadvantage because they only allow 5% or less of the key ingredients that make real change in the skin. By using natural formulas full of our patented and/or exclusive ingredients, we are doing much more good to the skin.
Most of our products are formulated to be vegan and gluten-free. Please check individual products for specific ingredient information.
The majority of our Skincare and Colour products are Oncology Friendly, you can view our Oncology Friendly products here.

Our stem cells come from carefully screened adult adipose tissue. There are no actual stem cells in StemFactor Growth Factor Serum, just the growth factors they make.
