Osmosis Catalyst AC-11 is a level 3 vitamin C serum built around AC-11, a patented cat's claw extract, alongside chirally-correct amino acids and skin-supporting minerals. It is formulated to support the skin's own repair processes for firmer, brighter, more even-looking skin. As a high-strength Osmosis MD serum, it is designed to be used under professional guidance.
What Is Catalyst AC-11?
Catalyst AC-11 is one of Osmosis's most advanced serums, positioned at level 3 in their system and suitable for all skin types. It combines a potent, stabilised vitamin C with a patented botanical extract and a complex of amino acids, aiming to support the skin's natural renewal rather than simply sitting on the surface. Because it is part of the Osmosis MD line, a short consultation ensures it fits your skin before your first purchase.
The AC-11 Ingredient
The serum is named for AC-11, a patented extract of Uncaria tomentosa (cat's claw). Its manufacturer reports that AC-11 has been clinically shown to support the skin's DNA repair processes by up to 33%, and it is protected by US patent. This is the ingredient that distinguishes Catalyst from an ordinary vitamin C serum, and the reason it sits in the premium MD line. Your consultation is the right place to discuss what that means for your skin.
Vitamin C, Amino Acids, and Minerals
Around the AC-11, the formula pairs several supporting actives. Stabilised L-ascorbic acid (vitamin C) provides antioxidant support and helps brighten and even the look of skin tone. A complex of amino acids, glycine, proline, lysine, and alanine, supplies the building blocks the skin uses for collagen and elastin. Zinc and copper support the skin's structural processes. Together they aim to support firmer, smoother, more radiant-looking skin over time.
What It Helps With
With consistent use under guidance, Catalyst AC-11 is used to support the appearance of:
- Firmness and elasticity
- Fine lines and wrinkles
- Uneven tone and the look of pigmentation
- The appearance of scars and broken capillaries
- Overall radiance and skin quality
It is a treatment serum for those focused on visible signs of aging and skin quality, not a quick fix.
Who It Is For
Catalyst AC-11 suits all skin types and is aimed at people seeking a high-strength, professional-grade serum for visible aging and skin quality, who are comfortable with the consultation-led MD model. It layers well with other Osmosis serums as part of a guided regimen.

How to Use Catalyst AC-11
After your consultation, shake lightly and apply 1 to 2 pumps to clean skin, morning and evening. It may be layered with other serums and followed with moisturiser. Always apply a broad-spectrum SPF in the daytime, this serum supports skin quality but does not provide sun protection, so daily sunscreen is essential. For an intensive step, some use several pumps as an evening treatment, as advised in your consultation.

Does Catalyst AC-11 replace sunscreen?
Catalyst AC-11 does not replace sunscreen. It is a treatment serum that supports skin quality and antioxidant defense, but it provides no SPF. Always apply a broad-spectrum sunscreen during the day, especially when using a vitamin C serum, since sun protection is essential to maintaining the results you are working toward.
