This fit is calculated for the concerns frequently associated with oily skin: shine, enlarged pores, blackheads, and blemishes. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily skin; other nourishing masks fit it better.

## Why this fit

- Offers moderate brightening for your oily skin due to the presence of ascorbic acid and niacinamide, which provide antioxidant support and help regulate sebum. Glycerin offers hydration, but the formula does not specifically target oily shine.
- The inclusion of collagen amino acids and superoxide dismutase offers general skin benefits, enhancing overall skin health.
- The product is safe for your oily skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing components like niacinamide and glycerin.

## Questions and answers

### How well does the C + Collagen Biocellulose Brightening Treatment Mask work for oily skin?

This mask works reasonably well for oily skin, offering moderate brightening and antioxidant support without causing irritation, though it does not specifically target oily shine. To work best for oily skin, a nourishing mask needs ingredients that control excess shine and regulate oil while keeping the complexion clear and balanced.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

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

Ascorbic acid and niacinamide make this mask a good fit for oily skin by providing antioxidant support and helping regulate sebum, while glycerin offers hydration. Oily skin requires a nourishing mask that specifically targets oily shine, controls excess oil, and promotes clarity and hydration without clogging pores.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

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

Vitamin C helps brighten skin tone and smooth texture while providing antioxidant protection that prevents sebum oxidation. For oily skin, this type of product typically needs to be paired with oil-controlling or pore-clearing ingredients like salicylic acid or plant extracts.
Sources: [International Journal of Cosmetic Science, 2005](https://pubmed.ncbi.nlm.nih.gov/18492184/), [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37128827/)

### What does Collagen do for oily skin?

Collagen helps keep oily skin hydrated and balanced without adding heaviness. It improves overall skin condition and helps maintain moisture levels, but an oily skin routine also needs ingredients that control excess oil and clear pores.
Sources: [Dermatology Practical & Conceptual, 2022](https://pubmed.ncbi.nlm.nih.gov/35223163/), [Current Issues in Molecular Biology, 2024](https://pubmed.ncbi.nlm.nih.gov/38534748/)

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

This mask fits into your weekly routine after cleansing and before moisturizing, on the evening scheduled for a treatment. It is safe for your oily skin and provides moderate brightening and general health benefits, though oily skin of this type also benefits from ingredients that specifically target excess shine.
Sources: [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36607762/), [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

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

You can use this mask in your weekly routine, keeping it on a separate day from your retinol to avoid irritation. Oily skin works best with products that balance oil and reduce shine while providing light hydration.

### How often should I use this mask?

This mask is used weekly as part of your routine. A nourishing mask for oily skin needs oil-controlling and mattifying ingredients that keep the skin clear and fresh while providing balanced hydration.

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

This mask is unlikely to clog pores or cause breakouts for oily skin, as it has a safe profile with no harsh ingredients that typically trigger irritation. To better care for oily skin, a product of this type needs ingredients that specifically target oily shine.

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

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