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 nourishing masks fit it better.

## Why this fit

- Offers moderate brightening and smoothing for your normal skin, as ascorbic acid and niacinamide work to improve skin tone and elasticity. Collagen amino acids and superoxide dismutase provide antioxidant support and hydration, though specialized ingredients for redness and irritation are absent.
- The formula is safe for your sensitive skin, with glycerin and niacinamide offering soothing benefits and no harsh or prohibited ingredients.
- This product provides general skincare advantages, but it does not specifically target your concerns of redness and irritation.

## Questions and answers

### How well does Dr. Dennis Gross C + Collagen mask work for sensitive skin?

This mask is an average fit for your sensitive skin, offering moderate brightening and smoothness while safely avoiding harsh ingredients. However, it does not specifically target redness and irritation, so a nourishing mask for this skin needs dedicated calming and soothing ingredients that actively relieve irritation and redness.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/), [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

Glycerin and niacinamide make this mask safe for sensitive skin by offering soothing benefits without harsh ingredients. However, because this mask is only an average fit for your skin, a product of this type needs specialized soothing ingredients that actively calm redness and irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### 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/), [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37128827/)

### What does Collagen do for sensitive skin?

Collagen helps soothe sensitive skin by reducing dryness, redness, and rough patches while keeping moisture locked in. It improves the skin barrier so it is less easily irritated, and studies show it is well tolerated and safe for sensitive skin types.
Sources: [International Journal of Cosmetic Science, 2009](https://pubmed.ncbi.nlm.nih.gov/19496838/), [Pharmaceutical Development and Technology, 2014](https://pubmed.ncbi.nlm.nih.gov/23675949/)

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

This mask goes in your weekly routine after a cleanser and enzyme powder, and before a treatment and moisturizer. To better calm sensitive skin, a mask of this type needs extra soothing ingredients that specifically target redness and irritation.

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

You can use this mask in your weekly routine, but it does not specifically target redness and irritation. To better fit sensitive skin, a mask of this type needs calming ingredients like ceramides and soothing botanical extracts.

### How often should I use this mask?

You can use this nourishing mask once a week as part of your weekly routine for sensitive skin. While the formula is safe and provides gentle hydration, this product of this type needs specialized ingredients that specifically target redness and irritation to be a better fit for your skin.

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

This mask is unlikely to clog pores or cause breakouts for sensitive skin, as it features a safe formula with soothing ingredients like glycerin and niacinamide. However, because it lacks specialized ingredients to calm redness and irritation, sensitive skin prone to these issues needs a product that includes targeted soothing agents and anti-inflammatory extracts.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

It has no drying alcohol and contains fragrance (linalool, citral, and limonene).
