Lovi Assistant explains
- Highly suitable for your normal skin, the Advanced Peptide Complex and Hexapeptide work to improve skin volume and elasticity, while Niacinamide offers anti-inflammatory benefits to address redness and irritation.
- PHA provides mild keratolytic action, further supporting skin texture and clarity for your normal skin type.
- The product is safe for your sensitive skin, with no risks of irritation due to the absence of harsh ingredients.
How to apply
- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .
