Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate suitability for normal skin, as antioxidants like Ergothioneine and Glutathione provide general skincare benefits and support for your redness and irritation.
  • While the formula contains Glycerin and Tocopherol for hydration and antioxidant protection, it lacks sufficient humectants to fully address your skin's hydration needs.
  • The product is safe for your sensitive skin, containing no harsh ingredients that would cause 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 .

Questions and answers

Why is Allies of Skin 20% Vitamin C Brighten + Firm Serum a weak match for sensitive skin?

Which ingredients make this serum a poor fit for sensitive skin?

This serum is a weak match for sensitive skin because it lacks enough hydrating humectants to fully meet your skin's hydration needs. To fit sensitive skin well, this type of product needs extra hydrating ingredients like glycerin alongside calming agents to soothe redness and irritation.

What does Ethylated L-Ascorbic Acid do for sensitive skin?

Ethylated L-Ascorbic Acid helps protect sensitive skin from daily environmental stress and UV damage while calming redness and irritation. It also helps brighten dark spots and keeps your skin smooth and glowing without causing harsh irritation.

Free Radical Biology & Medicine, 2025Journal of Cosmetic Dermatology, 2012

Where does it go in a skincare routine for sensitive skin?

You can use this serum with retinol by applying your retinol at night and this serum in the morning to keep your sensitive skin calm. This serum is a weak match for your sensitive skin because it lacks sufficient hydrators, so a product of this type needs extra moisture-attracting ingredients to keep dry skin soft and smooth.
