Lovi Assistant explains
- Offers excellent brightening and evening of skin tone for your oily skin, as niacinamide and tranexamic acid effectively target hyperpigmentation and inflammation, while also providing good seboregulation.

- 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.
How to apply
- Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
- Apply your serum after cleansing and toning, but before putting on your moisturizer.
- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.
