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 serums fit it better.

## Why this fit

- Offers moderate benefits for your oily skin, as glycerin provides humectant action, but it lacks strong seboregulating ingredients to directly address oily shine.
- The presence of 3-O-Ethyl Ascorbic Acid offers excellent brightening and evening of skin tone, while ingredients like Tocopheryl Acetate and Camellia Sinensis Leaf Extract provide antioxidant protection.
- The product is safe for your oily skin with no risks of irritation due to the absence of prohibited or harsh ingredients.

## Questions and answers

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

This serum works moderately well for oily skin, offering good brightening and antioxidant benefits while keeping skin safe from irritation. However, it lacks strong ingredients to directly control oily shine. To work best for this skin type, a product needs effective components like niacinamide or zinc PCA to manage excess oil and reduce pores, alongside soothing and hydrating agents that keep the skin comfortable.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/), [Polymers, 2023](https://pubmed.ncbi.nlm.nih.gov/37571190/)

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

Glycerin helps keep oily skin hydrated while 3-O-ethyl ascorbic acid brightens skin tone, and soothing ingredients like oat and licorice root extract make the formula safe and comfortable to use. Because it lacks strong oil-controlling ingredients, an oily skin type needs a treatment with ingredients like niacinamide, zinc PCA, and ferulic acid to manage excess shine and pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [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 Squalane do for oily skin?

Squalane helps keep oily skin soft and smooth without feeling heavy, though oxidized forms may sometimes trigger irritation. To work well for oily skin, this type of product needs lightweight, non-clogging ingredients that balance moisture without adding excess grease.
Sources: [The Journal of Investigative Dermatology, 2006](https://pubmed.ncbi.nlm.nih.gov/16778793/)

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

Apply this treatment in the evening as part of your routine. This timing helps keep your skin safe around sun exposure while delivering brightening benefits.

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

You can use this serum alongside retinol, but apply them at different times of day to keep your skin calm and avoid irritation. Use this brightening serum in your morning routine and your retinol product at night. Oily skin often benefits from pairing brightening treatments with oil-controlling ingredients like niacinamide or salicylic acid.

### How often should I use it?

You can use this treatment in the evening as part of your routine. An average fit for oily skin means this product works well, though oily skin types often benefit more from formulas that include strong oil-balancing ingredients.

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

This serum is unlikely to clog pores or cause breakouts for oily skin, as it is free of harsh ingredients and heavy oils. It does not cause purging because it does not contain exfoliating acids that speed up cell turnover.

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

Yes, it has no fragrance and no drying alcohol.
