Lovi Assistant explains
- Highly suitable for your oily, acne-prone skin as azelaic acid and niacinamide effectively target inflammation and oil production, reducing acne lesions and blemishes.
- Snail mucin further supports skin regeneration and hydration, complementing the primary actives for overall skin health.
- The formulation is safe for your skin, with no risks of irritation due to the absence of harsh ingredients.

- 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.
