Category: [Face masks](https://lovi.care/skincare/ie/best/face-masks)

This fit is calculated for the concerns frequently associated with combination skin: an oily T-zone, enlarged pores, and dry cheeks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

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

## Why this fit

- Offers moderate suitability for your combination skin, as Ascorbic Acid and Niacinamide provide antioxidant activity and melanogenesis regulation, though they do not directly target your oily shine concern.
- Glycerin and Collagen Amino Acids offer general hydration and antioxidant support, contributing to overall skin health.
- The product is safe for your combination skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing components.

## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/))
- Vitamin C mesotherapy produced a significant and earlier reduction in gingival pigmentation and higher patient satisfaction compared to topical gel in twenty healthy non-smokers with hyperpigmented gingiva, with both methods reducing the mean area fraction of melanin-forming cells at 6 months without causing pain. ([Clinical Oral Investigations, 2021](https://pubmed.ncbi.nlm.nih.gov/33966113/))

- Ascorbic acid 2-glucoside gel significantly reduced gingival melanin pigmentation after 4 weeks compared to placebo in 73 subjects with symmetric pigmentation. ([Journal of Periodontology, 2009](https://pubmed.ncbi.nlm.nih.gov/19186973/))

- Topical collagen tripeptide application improved skin wrinkles, elasticity, and density while reducing advanced glycated end products in 22 Asian women over 4 weeks. ([International Journal of Molecular Sciences, 2022](https://pubmed.ncbi.nlm.nih.gov/35163025/))
- Marine collagen extracted from Greenland halibut skin showed a non-cytotoxic effect on fibroblast cells and provided a slight skin hydration effect when incorporated into cosmetic hydrogel formulations at dosages of 0.1, 0.25, and 0.5% in 23 healthy volunteers. ([Marine Drugs, 2023](https://pubmed.ncbi.nlm.nih.gov/36827098/))

([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women.

- Topical superoxide dismutase formulations maintained physical stability and enzymatic activity for 6 months at 4 and 30 degrees C, and effectively inhibited UVB-induced skin erythema for 48 hours, whereas formulations combined with alpha-tocopherol were unstable. ([European Journal of Pharmaceutics and Biopharmaceutics, 2007](https://pubmed.ncbi.nlm.nih.gov/17196809/))

## Questions and answers

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

This mask works reasonably well for your combination skin by providing helpful antioxidants and general hydration, though it does not directly target oily shine. A product of this type needs soothing ingredients with no risk of irritation, benefits for managing oily shine, and extracts that balance both dry and oily areas effectively.
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 combination skin?

Ascorbic acid and niacinamide help brighten your skin, while glycerin and collagen amino acids keep it hydrated. However, this mask needs soothing ingredients and components that manage oily shine to be an ideal fit for combination skin.
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 combination skin?

Vitamin C helps brighten dull areas and smooth out uneven texture on combination skin while protecting against daily environmental stress. It may also help keep pores clear and skin firm by supporting collagen production, though drier spots may need an added moisturizer to stay comfortable.
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 combination skin?

Collagen helps keep combination skin smooth and hydrated by improving moisture and supporting elasticity. It is unlikely to cause irritation and may help reduce the appearance of fine lines while keeping the skin barrier balanced.
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 combination skin?

This mask goes in your weekly routine after a cleansing mask and hydrating toner, and before your moisturizer. To better fit combination skin, this type of product also needs ingredients that help balance oily shine.

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

You can use this mask in your routine with retinol, applying the mask first to nourish your skin before following with your retinol product. This product is unlikely to cause irritation due to its soothing components, though a mask for combination skin also needs ingredients that directly manage oily shine.

### How often should I use this mask?

This mask works for your combination skin on a weekly basis, providing hydration and helpful antioxidants without causing irritation. To truly help with oily shine, a product of this type needs ingredients that balance oil and target pores.

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

This mask is unlikely to clog pores or cause breakouts for your combination skin, as it has a safe profile with soothing components and no harsh ingredients. However, because it only offers moderate suitability for this skin type, combination skin needs products with ingredients that directly target oily shine.

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

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