Lovi Assistant explains
- Highly suitable for your dry and sensitive skin as Bifida Lysate Ferment and Glycerin offer excellent hydration and barrier support, while Squalane provides emollient action to smooth flaky skin.

- The product is safe for your skin, containing no harsh ingredients and featuring soothing components that minimize irritation risk.
How to apply
- Could be used as part of your AM or PM routine. Start using this moisturizer 3 times a week and move to daily use if your dry skin tolerates it well.
- Apply this moisturizer after cleansing and toner in the morning, or after your serum in the evening. Always pair it with SPF in the morning.
- Gently press a small amount of the moisturizer into your skin. Avoid rubbing it harshly to protect your sensitive skin.
- Apply the moisturizer on slightly damp skin to help with hydration absorption. This also works well for dry and flaky skin types.
- Do a patch test before your first use. Avoid the eye area to prevent any irritation.
