## Why this fit

- Offers moderate brightening and evening of skin tone for your oily skin due to niacinamide and sodium ascorbyl phosphate, which help treat dark spots and provide antioxidant activity.
- While the formula is generally hydrating and soothing, it lacks specialized ingredients to directly address your oily shine concerns.
- The product is safe for your oily skin, with no risks of irritation from harsh or prohibited ingredients.

([Antioxidants, 2022](https://pubmed.ncbi.nlm.nih.gov/36670913/))
- Upcycled low-molecular-weight anionic peptides from Citrus junos seeds protected UVR-irradiated keratinocytes and reconstructed skin tissue by scavenging reactive oxygen species, reducing paracrine cytokines, inhibiting melanin synthesis and TRP-2 expression, and increasing filaggrin, laminin-5, and type I collagen expression.

- Topical 2% niacinamide significantly decreased sebum excretion rate in Japanese individuals and casual sebum levels in Caucasian individuals compared to placebo or baseline. ([Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/))

## What reviewers say

Based on limited data, users with dull, dehydrated, or sensitive skin frequently praise this serum for its lightweight, hydrating formula that effectively brightens the complexion and fades hyperpigmentation over time.

## How to apply

- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.

## Questions and answers

### How well does SKINFOOD Yuja C Dark Spot Clear Serum work for oily skin?

This serum works moderately well for oily skin by helping fade dark spots and keeping skin bright and calm, but it lacks ingredients to directly control oily shine. A treatment for oily skin needs ingredients like niacinamide, zinc pca, and lightweight hydrators to manage excess oil and enlarged pores while keeping the skin comfortable.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Experimental Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22142309/)

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

Niacinamide and sodium ascorbyl phosphate make this serum a good fit for oily skin by helping fade dark spots and providing antioxidant activity. However, because it lacks specialized ingredients to directly address oily shine, a treatment for this skin needs ingredients like niacinamide, zinc PCA, and ferulic acid to control excess oil and pores while boosting radiance.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Experimental Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22142309/)

### What does Yuzu Fruit Extract do for oily skin?

Yuzu Fruit Extract helps brighten skin and supports firm, smooth skin by protecting against sun damage and boosting collagen. It is unlikely to feel heavy on oily skin, but because it tends to target dryness and aging, oily skin may also need lightweight ingredients that balance oil and clear pores.
Sources: [International Journal of Molecular Sciences, 2024](https://pubmed.ncbi.nlm.nih.gov/38338991/), [Antioxidants, 2022](https://pubmed.ncbi.nlm.nih.gov/36670913/)

### What does Vitamin C do for oily skin?

Vitamin C helps oily skin by reducing unwanted oil production and preventing oil from oxidizing on your face. It also provides effective antimicrobial action that keeps breakouts under control and helps clear up acne lesions.
Sources: [Drug Research, 2017](https://pubmed.ncbi.nlm.nih.gov/27756097/), [International Journal of Cosmetic Science, 2005](https://pubmed.ncbi.nlm.nih.gov/18492184/)

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

This serum goes in the evening routine, after cleansing and before moisturizing, for simplicity and extra safety around sun exposure. For oily skin, a product of this type needs mattifying ingredients to help control excess shine.

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

You can use this serum with retinol by applying the serum first to clean skin and following with your retinol product, or by using them on alternating nights to keep your skin calm. This product is safe for your skin, though an oily skin routine also needs specialized ingredients to control excess shine.

### How often should I use this serum?

You can use this treatment in the evening, and it is safe for your oily skin without risks of irritation. Oily skin also needs oil-controlling and mattifying ingredients to help manage shine.

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

This serum is unlikely to clog pores or cause breakouts on oily skin, as its formula avoids harsh or irritating ingredients. However, because it lacks oil-controlling ingredients, an oily skin routine also needs lightweight, oil-absorbing ingredients like salicylic acid or clay to fully manage shine.

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

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