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

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

## Why this fit

- Offers moderate brightening for your combination skin, as niacinamide and sodium ascorbyl phosphate help even skin tone and provide antioxidant activity. Glycerin and allantoin offer supportive hydration and calming effects beneficial for your acne, blemishes, and breakouts.
- The formula is highly suitable for combination skin due to the melanogenesis regulation provided by niacinamide and sodium ascorbyl phosphate.
- The safety profile is excellent, with no risks of irritation for your combination skin due to the absence of prohibited or harsh ingredients.

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

Vitamin C helps control oily skin by reducing facial oil and can significantly decrease inflammatory pimples when used consistently. It also works well with other acne treatments to fade dark spots left behind by breakouts.
Sources: [Drug Research, 2017](https://pubmed.ncbi.nlm.nih.gov/27756097/), [International Journal of Cosmetic Science, 2009](https://pubmed.ncbi.nlm.nih.gov/19134126/)

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

This serum goes in your evening routine, as treatments with active ingredients are placed at night for simplicity and extra safety around sun exposure. It is unlikely to irritate your acne-prone skin since it has an excellent safety profile, but this skin type also needs oil-controlling ingredients and gentle exfoliants to truly thrive.

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

You can use this serum with retinol, applying this treatment first and following with your retinol once it absorbs. This product is unlikely to cause irritation due to its gentle formula, but acne-prone skin often does better with ingredients that deeply soothe breakouts and balance oil.

### How often should I use this serum?

You can use this serum in the evening as part of your routine. An average fit for acne-prone skin means this product works, but this skin type generally needs soothing ingredients like centella asiatica, green tea, or zinc to better calm breakouts and control oil.

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

This serum is unlikely to clog pores or cause breakouts for acne-prone skin because it has an excellent safety profile without harsh ingredients. To work best for breakout-prone areas, this type of product needs soothing ingredients and gentle brighteners like niacinamide and allantoin to calm the skin.
