What the product description says

“Protects skin from premature aging, dullness and pigmentation spots.”

Source: N/A

This product contains sodium ascorbyl phosphate. This ingredient could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

This ingredient sodium ascorbyl phosphate might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.

Sodium ascorbyl phosphateEffect: LowA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~6.9–10.3%
