What does the product description say?

For a refreshed and youthful-looking skin.

Source: German Drugstore

Effective ingredients missing or their concentration is too low.

magnesium ascorbyl phosphate 2% - 3%

Irritation risk:

Concentration: Insufficient!

A derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high

ascorbyl palmitate 0.9% - 1.35%

Irritation risk:

Concentration: Insufficient!

Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.

Moisturizing

What does the product description say?

The formulation with a Duo-Vitamin C Power Booster protects the skin from harmful environmental influences, has an intensive caring effect and provides valuable moisture.

Source: German Drugstore

Does not contain good ingredients to help with moisturization.

glyceryl caprylate 0.4% - 0.95%

Irritation risk:

Concentration: Effectiveness: LOW

An emollient that can also help water and oil mix together, as well as prevent bacteria growth in products
