Lovi Assistant explains
- Offers excellent brightening and evening of skin tone for your combination skin, as niacinamide and capryloyl salicylic acid work to exfoliate and enhance radiance. Cystoseira tamariscifolia extract and carnosine further support skin clarity and protection.
- The formula is highly suitable for your combination skin, with niacinamide and capryloyl salicylic acid providing effective seboregulation and moderate exfoliation to address oily shine.
- The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components like niacinamide and dipotassium glycyrrhizate.
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 .
