Lovi Assistant explains
- Highly suitable for your combination skin, this serum features niacinamide and Palmitoyl Hexapeptide-19 to support your skin barrier and stimulate collagen for improved elasticity. Glycerin and sea water provide essential hydration, which is beneficial for managing oily shine on combination skin, though not specifically targeted for this concern.
- The presence of Palmitoyl Tripeptide-38 further enhances the firming and plumping effects, contributing to a smoother skin appearance.
- This formula is safe for your skin, with no risks of irritation due to the absence of harsh ingredients.
How to apply
- Use your serum as part of your PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply the serum after cleansing and toner, and right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏳for it to soak in.
- Apply the serum on clean and dry skin since your skin is not sensitive.
- Always do a patch test before using the serum for the first time, and avoid the eye area .
