Lovi Assistant explains
- Suitable for normal skin due to the humectant action of glycerin and hyaluronic acid, which support skin hydration, but these ingredients offer general skincare benefits that are mostly supportive and irrelevant for your main goal of pigmentation.
- Acetyl hexapeptide-8 and palmitoyl tripeptide-1 provide moderate plumping by improving volume and elasticity, which is a secondary benefit for your skin concerns.
- The product is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Apply this serum as part of your PM routine starting 3x/week and build up to daily use if your skin likes it.
- Place the serum after cleansing and toning, but before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and wait a minute for it to absorb.
- Apply the serum on dry skin to help fade pigmentation effectively.
- Avoid the eye area and always use SPF 30+ during the day.

Why other serums fit skin with dark spots better
Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.
