Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate benefits for oily shine and acne-prone skin due to the presence of salicylic acid and niacinamide in concentrations that offer mild exfoliation and sebum regulation.
- The formulation is highly suitable for oily skin, with niacinamide and salicylic acid working to control sebum and gently exfoliate.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of prohibited or harsh ingredients.
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.
