Lovi Assistant explains
- High suitability for your oily skin is provided by niacinamide for oil regulation and willow bark extract for mild exfoliation, complementing the barrier-repairing benefits of Bifida Lysate Ferment and peptides like Palmitoyl Oligopeptide that also address fine lines.
- The inclusion of Allantoin and Beta-Glucan further supports skin barrier resilience and offers soothing effects, beneficial for maintaining overall skin health.
- The product demonstrates a strong safety profile with no irritation risks for oily skin, thanks to soothing ingredients and the absence of harsh components.
How to apply
- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.
