What is Ethyated Ascorbic Acid?
The Ordinary Ethylated Ascorbic Acid is a direct-acting vitamin C serum for brightening.
Ethylated Ascorbic Acid 15% is one of the many Vitamin C products The Ordinary offers. It targets;
- Antioxidant support
- Uneven Skin Tone
- Signs of Ageing
- Dullness
The Ordinary: Ethylated Ascorbic Acid 15% Solution is an advanced, direct-acting oil-like serum that helps visibly reduce signs of aging by brightening and balancing uneven skin tone. Among our other vitamin C offerings, what sets this formula apart is its ethylation which gives a small molecular size, allowing for faster visible results with less irritation potential.
Ethylation is a process which helps promote the stability of Vitamin C while still retaining the direct-acting benefits when compared to other Vitamin C Derivatives. And because it has advanced antioxidant properties, this water-free formula protects your skin from the visual effects of damage caused by environmental stressors, helping to maintain a more radiant complexion.
