Vitamin C is one of skincare’s most celebrated ingredients for good reason. It helps visibly brighten, improve the look of uneven tone, and support skin’s defense against oxidative stress. But here’s the thing, not all Vitamin C works the same.

The problem with most vitamin C?

Many formulas use L-Ascorbic Acid, which can be unstable. It oxidizes quickly (meaning it loses potency), may cause irritation, and can lose effectiveness before you finish the bottle.

The MUTHA Difference

In the No. 1 Serum, we use THD Ascorbate, a more stable, oil-soluble form of Vitamin C that stays potent longer and is known to penetrate effectively.
Paired with Ferulic Acid (an antioxidant that helps support Vitamin C’s benefits and helps defend against free radical damage), you get maximum brightening benefits and antioxidant support without the sting.
