Hi Isabell ❤️
The difference between La Roche-Posay Pure Vitamin C10 and Vitamin C12 mainly lies in the formulation. Both contain 10% pure vitamin C (ascorbic acid), but C12 has a more stable composition and may be better for sensitive skin. Some also find that it provides a more even release of vitamin C over time.
If you want a stronger effect, it might be wise to check the rest of the ingredient list to see which one suits your skin type best! 😊
Feel free to take the skin test if you want a recommendation and are unsure about what to go for ❤️
Wishing you a lovely day ahead
