Lovi Assistant explains
- Excellent suitability for your combination skin and acne concerns is provided by Bifida Lysate Ferment and Willow Bark Extract, which work to repair your skin barrier and offer mild exfoliation. Niacinamide and Beta-Glucan further support barrier function and hydration, enhancing overall skin health.
- The presence of peptides like Palmitoyl Oligopeptide and Copper Tripeptide-1 contributes to anti-aging benefits by promoting collagen production and minimizing fine lines, complementing the primary acne-fighting ingredients.
- The product demonstrates a strong safety profile with no reported risks of irritation for acne-prone skin, thanks to its formulation free of harsh ingredients and inclusion of soothing agents.
How to apply

- 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.
