Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and evening of skin tone for your normal skin, as 3-O-Ethyl Ascorbic Acid and Niacinamide work to treat dark spots and regulate melanogenesis.
  • The inclusion of Glycerin and Niacinamide provides supportive hydration and barrier function, which can help with your redness and irritation.
  • The product is safe for your sensitive skin, as it lacks harsh ingredients and carries no risk of 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 .

Where does this serum go in a skincare routine for sensitive skin?

This serum goes in your evening routine, applied after a soothing toner and before your moisturizer. Sensitive skin needs a gentle treatment that hydrates, calms redness, and evens out skin tone without harsh ingredients.

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 product, but because this skin requires extra care, look for products that include soothing ingredients and gentle hydrators to keep your skin calm and smooth.

How often should I use this serum?

This serum works for sensitive skin when used in your evening routine once a week to start. Sensitive skin of this type needs products with soothing ingredients like glycerin and niacinamide to keep the skin calm and hydrated.

Can this serum clog pores, cause breakouts or purging for sensitive skin?

This serum is unlikely to clog pores or cause breakouts for sensitive skin, as it has a safe profile and lacks heavy ingredients that trap oil. However, because it contains salicylic acid, it may occasionally cause mild purging as it clears out pores.

Is this serum fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (limonene, geraniol, and citronellol).
