BENEFITS

The most potent & stable Vitamin C serum for face currently available on the market. Combined with Aloe Vera, Squalene, and natural oils for nourishment and suitability on sensitive skin.

Not all Vitamin C is made equal. Most Vitamin C serums use ascorbic acid: a cheaper, low-pH/acidic, harsh-on-skin form with inferior absorbability. C-Major uses highly absorbable, oil-soluble Vitamin C THDA. This Vitamin C form is scientifically gentler on the skin due to its superior stability, penetrates skin much deeper, and combines better with other products. Vitamin C THDA is uncommon in typical mass-produced Vitamin C products… and the only form we use.
