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 suitability for your oily skin, as niacinamide and capryloyl salicylic acid provide mild oil control and exfoliation to help with breakouts. While these ingredients offer some benefits for your primary concerns, the formula lacks stronger agents for optimal acne management.
- The inclusion of niacinamide and ascorbic acid effectively brightens and evens your skin tone, supporting your additional goal of reducing oiliness or shine.
- The product is generally safe for your oily skin, though the presence of alcohol and ascorbic acid carries a slight risk of irritation.

## Questions and answers

### How well does Numbuzin Vitamin-Niacinamide Concentrated Pad work for oily acne-prone skin?

This product offers moderate suitability for your oily, acne-prone skin, as niacinamide and capryloyl salicylic acid provide mild oil control and help with breakouts. While it is generally safe, it carries a slight risk of irritation from alcohol and ascorbic acid and lacks stronger agents for optimal acne management. A product of this type needs effective ingredients like niacinamide and propolis or benzoyl peroxide to provide excellent skincare benefits without irritation, along with a comfortable blend of soothing extracts and hydrators for daily use.
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/)

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

Niacinamide and capryloyl salicylic acid help control oil and clear breakouts for your oily acne-prone skin. To better manage breakouts and suit this skin type, a product needs stronger targeted acne-fighting ingredients along with soothing extracts and lightweight hydrators.
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 Niacinamide do for oily acne-prone skin?

Niacinamide helps balance oil production, calms redness, and is unlikely to irritate oily, acne-prone skin while improving blemishes. Clinical tests show it reduces excess oil and helps clear up both inflammatory and non-inflammatory acne breakouts.
Sources: [Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38299457/)

### What does Glutathione do for oily acne-prone skin?

Glutathione helps protect oily, acne-prone skin from daily stress and irritation by acting as an antioxidant that supports a healthy skin barrier. It is unlikely to clog pores, but this skin type also needs ingredients that clear out oil and soothe redness to stay calm and smooth.
Sources: [Journal of the European Academy of Dermatology and Venereology, 2024](https://pubmed.ncbi.nlm.nih.gov/38189670/), [Current Problems in Dermatology, 2001](https://pubmed.ncbi.nlm.nih.gov/11225199/)

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

This treatment goes in the evening routine. For oily acne-prone skin, this product offers moderate oil control and brightening, but an average fit for acne requires stronger active ingredients and blemish-clearing agents.
Sources: [International Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/31461548/)

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

You can use this treatment with retinol, but it is best to apply retinol first and follow with this pad to help prevent irritation. While this product offers moderate suitability for oily skin, it lacks the stronger agents needed for optimal acne management, so an oily skin type typically requires powerful blemish-fighting ingredients like salicylic acid or benzoyl peroxide.

### How often should I use this treatment?

Use this treatment once a week in the evening, and if your oily skin tolerates it well and shows good results, you can carefully use it more often. Oily acne-prone skin needs a product of this type with stronger exfoliating and blemish-clearing ingredients for optimal acne management.

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

Numbuzin Vitamin-Niacinamide Concentrated Pad works for your oily acne-prone skin, though other products fit it better. It provides mild oil control and helps with breakouts, but a product of this type needs stronger acne-fighting agents and gentle pore-clearing ingredients to best manage breakouts without irritation.
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/)

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

It has no fragrance and contains drying alcohol (alcohol).
