Glycolic acid belongs to the alpha-hydroxy acid (AHA) family and stands out as one of the most effective exfoliating ingredients in skincare. With the smallest molecular size among AHAs, it penetrates skin easily to dissolve the bonds between dead skin cells, revealing fresher skin underneath.

Glycolic acid occurs naturally in sugar cane, but can also be found in fruits like grapes and citrus. In skincare formulations, glycolic acid is typically synthesized in laboratories to ensure purity and consistent concentration levels.

Caudalie's glycolic acid formulations draw inspiration from vineyard science, combining this powerful AHA with grape-derived antioxidants for enhanced efficacy.

Glycolic acid offers multiple benefits that make it a staple in advanced skincare routines:

• Effectively removes dead skin cells to reveal brighter, smoother skin

• Helps to clear dark spots on the face and reduce hyperpigmentation,

• Stimulates collagen production for firmer, more youthful-looking skin,

• Improves skin texture and minimizes the appearance of fine lines,

• Enhances the absorption of other skincare products.

When used consistently, glycolic acid for hyperpigmentation can significantly lighten dark spots on the face and create a more even complexion.

Vitamin C works through several mechanisms to improve skin appearance:

• Neutralizes free radicals caused by UV exposure and pollution,

• Inhibits melanin production to prevent dark spots formation,

• Boosts collagen synthesis to improve skin firmness,

• Strengthens the skin barrier function.

Using glycolic acid with vitamin C can be effective but requires careful consideration of formulation stability, skin sensitivity, and application timing.

Combining these ingredients offers complementary benefits:

• Glycolic acid exfoliates and removes dead skin cells, allowing vitamin C to penetrate more effectively,

• Together, they provide enhanced brightening effects for stubborn hyperpigmentation,

• The combination accelerates cell turnover while providing antioxidant protection,

• Both ingredients work to reduce dark spots through different mechanisms.

The exfoliating action of glycolic acid paired with vitamin C's ability to inhibit melanin production creates a powerful strategy to lighten dark spots on the face.

While vitamin C offers excellent benefits, it's not the only option for treating hyperpigmentation.

Caudalie's Vinoperfect range features Viniferine, a patented ingredient derived from vine sap that outperforms vitamin C for dark spot correction. In vitro tests show Viniferine is 62 times more effective than vitamin C at inhibiting tyrosinase, the enzyme responsible for dark spot formation.

Unlike vitamin C, Viniferine remains stable in formulations, doesn't oxidize, and suits even the most sensitive skin types. This vitamin C alternative delivers exceptional results for those looking to eliminate age spots and achieve luminous skin without the potential irritation or stability issues of traditional vitamin C.

When using glycolic acid with vitamin C, proper application order and timing are essential for maximizing benefits while minimizing potential irritation.

Finding the right frequency depends on your skin's tolerance and product concentration:

• High-concentration treatments like the Vinoperfect Glycolic Peel Mask should be limited to twice weekly, even for experienced users,

• Daily glycolic acid products, such as essences and night creams, can be incorporated into your everyday routine once your skin has acclimated,

• Vitamin C or alternatives like Viniferine can typically be used twice daily,

• Always amplify your sun protection when using glycolic acid products, as they can increase photosensitivity.

The Vinoperfect range offers a complete brightening solution with Viniferine and glycolic acid working together to target dark spots and reveal luminous skin.
