Lovi Assistant explains
- Suitable for normal skin, this serum offers excellent brightening and smoothing texture due to ascorbic acid and hyaluronic acid, which visibly improve skin tone and elasticity.
- While providing general hydration and antioxidant support, the formula is not specialized for targeting your wrinkles and fine lines.
- The product is safe for your skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing components like glycerin and tocopherol.
How to apply
- Use this serum in your PM routine. Start by applying it 3 times a week, and work up to daily use if your skin likes it.
- Apply this serum after your toner and before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- You can apply the serum on dry skin for the best results against fine lines.
- Always do a patch test before your first use and avoid the sensitive eye area.

Questions and answers
How well does La Roche-Posay Pure Vitamin C12 Sérum work for mature skin?
La Roche-Posay Pure Vitamin C12 Sérum works for mature skin, though other products fit it better because this formula is not specialized for targeting wrinkles and fine lines. It helps brighten and smooth texture while providing safe, gentle hydration with no risks of irritation. Treatments that fit mature skin better need high concentrations of potent antioxidants, peptides, and humectants to effectively target wrinkles and fine lines.

Which ingredients make this serum a good fit for mature skin?
Ascorbic acid, glycerin, and hyaluronic acid make this serum a good fit by brightening your tone, smoothing your texture, and providing hydration. To better target wrinkles and fine lines, a treatment of this type needs specialized anti-aging ingredients and peptides to improve firmness.

What does Vitamin C do for mature skin?
Vitamin C helps mature skin by smoothing out wrinkles, brightening dark spots, and boosting firmness. It works by encouraging collagen production to keep skin looking youthful and radiant.
What does Glycerin do for mature skin?
Glycerin helps keep mature skin feeling soft and smooth by drawing moisture into the outer layer and locking it in. This daily hydration boost supports the skin barrier, keeping dry areas comfortable and protected against irritation.
