Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- This product offers high suitability for normal skin, as retinaldehyde and hyaluronic acid promote cell turnover and hydration without significant irritation for you. Tocopherol Vitamin E and hyaluronic acid provide antioxidant protection and hydration, which are supportive for your redness and irritation.
- The formulation is safe for your sensitive skin, with no harsh ingredients and the inclusion of soothing agents like Vitamin E and hyaluronic acid.
- It offers excellent skin rejuvenation and hydration, though it lacks targeted ingredients to directly address your specific concerns of redness and irritation.
How to apply
- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .
