This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers excellent brightening and evening of skin tone for your normal skin due to the presence of 3-O-Ethyl Ascorbic Acid and Tocopheryl Acetate, which provide antioxidant activity and support skin health.
- While Glycerin and Oat extract offer general hydration and soothing benefits that can support your redness and irritation, they are not specifically targeted to address these concerns.
- The product is safe for your normal skin with sensitivity, as it lacks prohibited or harsh ingredients that could cause irritation.

## Questions and answers

### How well does First Aid Beauty 10% Vitamin C Brightening Serum work for sensitive skin?

First Aid Beauty 10% Vitamin C Brightening Serum works moderately well for sensitive skin, as it is safe and brightens nicely but lacks specific ingredients targeted for redness and irritation. To fit sensitive skin better, a treatment of this type needs effective ingredients for redness and irritation, along with potent antioxidants, hydrating components, and skin-repairing ingredients.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### Which ingredients make this serum a good fit for sensitive skin?

Oat and glycerin make this serum a good fit for sensitive skin by offering gentle hydration and soothing benefits that help calm redness and irritation. Treatments that fit this skin best need ingredients like niacinamide and snail secretion filtrate to actively target redness and irritation without causing irritation.

### What does Vitamin C do for sensitive skin?

Vitamin C helps brighten skin, smooth out fine lines, and fade dark spots. Clinical studies show it is generally safe and well-tolerated when improving overall skin quality.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### What does Squalane do for sensitive skin?

Squalane helps calm sensitive skin by defending against everyday irritation and keeping it smooth and soft. It is unlikely to cause irritation and supports your skin barrier so it stays comfortable and hydrated.
Sources: [International Journal of Molecular Sciences, 2017](https://pubmed.ncbi.nlm.nih.gov/29280987/)

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

This treatment serum goes in your evening routine, after cleansing and toning and before moisturizing, for simplicity and extra safety around sun exposure. A sensitive skin routine needs soothing ingredients like oat extract and glycerin to calm redness and irritation.

### Can I use this serum with retinol, and in what order?

It is best to use this serum in the morning and your retinol at night to help avoid skin irritation. When using both in your routine, this product needs calming ingredients like centella asiatica or ceramides and gentle hydrators to properly protect sensitive skin.

### How often should I use this serum?

This serum works best in your evening routine, starting once a week so your sensitive skin can adjust safely. This type of product needs extra soothing ingredients and gentle hydrators to keep dry skin calm and comfortable.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### 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 because it lacks heavy ingredients that trap oil and is safe for easily irritated skin. However, since it is a vitamin C treatment, you might experience a few tiny blemishes or purging as your skin adjusts to the active ingredients.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
