Lovi Assistant explains
- This serum offers moderate benefits for your normal skin, as 3-0-Ethyl Ascorbic Acid and Niacinamide work to brighten and even skin tone, while Camellia Sinensis Leaf Water and Allantoin provide soothing and hydration supportive for redness.
- The formulation is safe for your sensitive skin, containing no harsh ingredients that could cause irritation.
- It provides general skincare benefits that support your concerns without being overly specialized.
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 .

Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the serum first and following it with your retinol, or by using them on alternate nights to keep your sensitive skin calm. Because this product has an average fit for your skin, sensitive skin needs a product that includes extra soothing plant extracts and gentle hydrators to prevent dryness and irritation.
