Lovi Assistant explains
- This formulation offers moderate benefits for your redness and irritation, as ingredients like Glycyrrhiza Glabra Root Extract and Bisabolol help to soothe and calm the skin, while Hydrolyzed Sodium Hyaluronate and Glycerin provide excellent humectant action for your normal skin.
- It provides good protection against environmental stressors due to antioxidants like ergothioneine and tetrahexyldecyl ascorbate.
- The safety profile is excellent, with no risks of irritation for your sensitive skin due to the absence of harsh ingredients and the presence of soothing components.
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 .
