Lovi Assistant explains
- Suitable for normal skin due to the presence of Sodium Hyaluronate and Gigartina Skottsbergii Extract, which provide humectant action and barrier repair.
- While it offers moderate moisturizing benefits, the ingredients are not specifically targeted to address your main goal of pigmentation.
- The product is safe for your normal skin, with no risks of irritation from harsh ingredients.
How to apply
- Could be used as part of your AM and PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply this moisturizer after your cleanser and toner, right before your morning SPF.
- Gently press a small amount of the moisturizer into your skin. Avoid rubbing it too hard so it absorbs nicely.
- For the best moisture, you can apply it when your skin is slightly damp. This helps your skin stay soft and happy.
- Remember to avoid the eye area when applying. Always do a patch test before your first use.
