Lovi Assistant explains
- Suitable for normal skin due to the presence of niacinamide with seboregulating and anti-inflammatory actions, and glycerin with humectant action, this serum offers moderate skin brightening and pore minimizing benefits. Glycerin provides general skincare benefits such as hydration, which are mostly supportive for your main goal of pigmentation.
- The formula is safe for your normal skin, as it lacks prohibited or harsh ingredients and includes soothing components like niacinamide and glycerin.
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.

What does Niacinamide do for skin with dark spots?
Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
What does Glycerin do for skin with dark spots?
Glycerin helps keep dry skin hydrated and supports a healthy skin barrier, which makes skin feel soft and smooth. While it does not directly fade dark spots on its own, it is often added to spot-fading products to keep the skin comfortable while other ingredients work.
