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 brightening and evening of skin tone for you due to the presence of niacinamide and sodium ascorbate, which help reduce hyperpigmentation and promote skin tone evenness.
- While niacinamide offers seboregulation and anti-inflammatory action beneficial for your oily skin, the formula's primary focus on brightening is less relevant to your main goal of managing oily shine.
- The product is safe for your oily skin, with no risks of irritation from harsh ingredients.

## Questions and answers

### How well does Vitamin B3 Brightening Serum work for oily skin?

This serum works moderately well for oily skin because its focus is brightening rather than managing oily shine, though it is safe and has no risk of irritation. Oily skin needs ingredients that control oil and enlarged pores, such as niacinamide, ferulic acid, and zinc PCA, alongside barrier-supporting ingredients that do not clog pores.

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

Niacinamide makes this serum a good fit for oily skin because it helps control excess oil and calms inflammation. A treatment for oily skin needs ingredients like niacinamide and zinc PCA to manage shine, alongside soothing extracts and light hydrators.
Sources: [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

### What does Niacinamide do for oily skin?

### What does Glycerin do for oily skin?

Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [International Journal of Toxicology, 2019](https://pubmed.ncbi.nlm.nih.gov/31840548/)

This serum goes in the evening routine for oily skin, as treatments with active ingredients are placed then for simplicity and extra safety around sun exposure. It is safe for your oily skin with no risks of irritation from harsh ingredients, though its focus is on brightening rather than managing oily shine.

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

You can use this treatment alongside a retinoid product, applying the treatment in your morning routine and the retinoid at night. This approach keeps your oily skin calm while helping avoid the irritation that can happen when using multiple strong active ingredients at the same time.

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

This serum is unlikely to clog pores or cause breakouts for oily skin, as it has a safe profile with no harsh ingredients that typically cause irritation. To properly care for oily skin, a product of this type needs ingredients that help control excess oil and shine alongside a lightweight feel.
