Which ingredient is often used to lighten pigmentation?

Vitamin C is widely recognized for its role in brightening skin and inhibiting melanin production, which is crucial for reducing pigmentation. It acts as an antioxidant, helping to protect the skin from damage caused by free radicals while promoting a more even skin tone.

Alpha hydroxy acids, on the other hand, are commonly used for exfoliation. They work by dissolving the bonds that hold dead skin cells together, facilitating their removal and revealing fresher, more radiant skin underneath. This exfoliation process can also help in diminishing the appearance of dark spots and pigmentation over time.

When both Vitamin C and AHAs are used in combination, they can effectively target pigmentation issues. The exfoliating property of AHAs enhances the penetration and efficacy of Vitamin C, making the overall approach to lightening pigmentation more effective. Therefore, the correct response encompasses both AHAs and Vitamin C, reflecting their complimentary roles in addressing skin pigmentation.
