Vitamin C 35% & Glutathione Advanced Firm + Brighten Serum

This product is safe for use during pregnancy. We always recommend to ask your doctor prior the use.

Vitamin C brightens skin through multiple mechanisms by:
Neutralizing free radicals from UV exposure and pollution that cause skin darkening.
Creating synergistic brightening effects that helps fade uneven tone and reveal radiant skin through its 35% vitamin C.

For more experienced Vitamin C users, our 35% Vitamin C serum can offer an intensified approach to brightening and antioxidant support. Higher concentrations are often chosen by those whose skin has already built tolerance and who are looking to target stubborn dullness, uneven tone, or visible signs of aging more aggressively.

Yes. We don't recommend combining retinoids with acids (AHAs or BHAs) in the same routine, as this can be too intense for most skin types and may cause dryness, irritation, or barrier compromise. Instead, alternate them by using retinol one night and your exfoliating acid on another. Similarly, avoid using multiple acid-containing products together in the same routine—instead, use one in the morning and another in the evening. This approach lets you enjoy the benefits of both without overwhelming your skin.

If you experience any sensitivity, take a short break from active treatments to allow your skin to reset and rebuild its natural barrier. During this time, focus on soothing, hydrating products like our Copper Tripeptide & Ectoin Advanced Repair Serum. Once your skin feels balanced, slowly reintroduce actives one at a time.

We recommend applying serums in order of consistency, from lightest water-based formulas to heavier oil-based or creamy ones, to ensure optimal absorption and effectiveness. Our serums from thinnest to thickest are: 35% Vitamin C+ Perfecting Serum, Multi Peptides & GF (Growth Factor) Advanced Lifting Serum, Tranexamic & Arbutin Advanced Brightening Serum, Copper Tripeptide & Ectoin Advanced Repair Serum, Vitamin C 20% & Citrus Cells Advanced Light Reflecting Serum, and Beta Glucan & Resveratrol Advanced Hydrating Serum.

However, exfoliating serums like our Azelaic & Kojic Advanced Clarifying Serum and Mandelic Advanced Pigmentation Night Serum should always be applied first, regardless of their consistency, as they prepare the skin's surface to accept other actives.
