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

Works for oily acne-prone skin; other serums fit it better.

## Why this fit

- Offers moderate exfoliation and pH modulation suitable for your oily skin, with gluconolactone and citric acid helping to manage excess sebum. While it provides excellent brightening and evening of skin tone due to multiple forms of vitamin C like 3-O-Ethyl Ascorbic Acid and Tetrahexyldecyl Ascorbate, these benefits are not specifically targeted for your acne, blemishes, and breakouts.
- The inclusion of glycerin and squalane offers general hydration, which is supportive for your skin. Caffeine and squalane contribute to a good safety profile with no risks of irritation for your oily skin.
- The product is safe for your skin as it lacks prohibited or harsh ingredients and contains soothing components.

## Questions and answers

### How well does Youth to the People 15% Vitamin C + Clean Caffeine Energy Serum work for oily acne-prone skin?

This serum is an average fit for oily acne-prone skin, as it brightens and helps manage excess oil, but it does not specifically target blemishes and breakouts. To work better for this skin type, a treatment needs ingredients like niacinamide and propolis that control oil and tackle breakouts without causing irritation.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

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

This serum works for your skin because gluconolactone and citric acid help manage excess oil, while multiple forms of vitamin C brighten your tone. To better fit oily acne-prone skin, a product of this type needs ingredients like niacinamide and propolis that directly target blemishes and breakouts while controlling excess oil.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/), [Journal of Drugs in Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23545907/)

### What does Vitamin C do for oily acne-prone skin?

Vitamin C helps brighten skin, smooth out texture, and improve uneven spots for oily acne-prone skin. It may also help fade marks left behind by blemishes.
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 Caffeine do for oily acne-prone skin?

Caffeine helps reduce puffiness and calm redness in oily, acne-prone skin. It is unlikely to cause breakouts and may help refresh tired-looking areas.

### Where does this serum go in a skincare routine for oily acne-prone skin?

This treatment goes in the evening routine after cleansing and before moisturizing, though an average fit for oily acne-prone skin means this type of product works best when it also includes ingredients that target breakouts directly.

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

You can use this serum with retinol by applying the vitamin C serum in the morning and your retinol at night to avoid irritation. To work well for oily acne-prone skin, this type of product needs ingredients that directly target breakouts and blemishes alongside oil control and brightening.

### How often should I use this serum?

You can use this treatment in the evening, and some similar serums may also be used in the morning or twice a day. For oily acne-prone skin, this product works, though an acne-focused serum with salicylic acid, benzoyl peroxide, or retinoids would fit your skin better.

### Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?

This serum is unlikely to cause breakouts or clog pores on oily skin because it lacks harsh or prohibited ingredients and includes soothing components with a good safety profile. However, because it does not specifically target acne and blemishes, oily acne-prone skin needs a product that includes targeted blemish-fighting ingredients and oil-balancing agents.

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

Yes, it has no fragrance and no drying alcohol.
