Lovi Assistant explains
- Offers moderate suitability for your combination skin as retinol and niacinamide work to regulate desquamation and sebum production, respectively, aiding in texture refinement and reducing fine lines. While beneficial for general skin renewal, the retinol concentration provides moderate exfoliation that is supportive rather than primary for your acne and breakouts.
- The formula includes soothing ingredients like niacinamide and hyaluronic acid, ensuring a gentle experience without irritation for your combination skin.
- The safety profile is excellent, with no harsh ingredients and a formulation designed to be non-irritating.
How to apply
- Use your serum as part of your PM routine and start 3x/week before working up to daily use.
- Apply this treatment after cleansing and toner, and before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the product on clean, dry skin to help manage your breakouts safely.
- Avoid the eye area and do a patch test before your first use.
