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

## Why this fit

- Offers moderate plumping for your oily skin due to acetyl octapeptide-3 and acetyl hexapeptide-8, while rice starch and betaine help manage excess sebum. Glycerin and sodium hyaluronate provide general hydration, though these ingredients are not primary treatments for your acne, blemishes, and breakouts.
- The formula is safe for your oily skin, containing no harsh or prohibited ingredients that would cause irritation.
- It provides excellent suitability for oily skin due to humectant action and sebum management.

- A combination of Aloe barbadensis leaf extract and trimethylglycine in a 1:1 mass ratio synergistically increased aquaporin 3 expression by up to 380% in keratinocytes and safely improved skin hydration in healthy volunteers. ([Molecules, 2024](https://pubmed.ncbi.nlm.nih.gov/38611819/))
- Treatment with cross-linked hyaluronic acid-based microneedle patches combined with acetyl hexapeptide-8 or epidermal growth factor significantly improved wrinkles and skin hydration compared to the patch alone in Korean females over 29 days.

- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.

## Questions and answers

### How well does PCA SKIN ExLinea Pro work for oily acne-prone skin?

This serum works moderately well for oily skin by offering some plumping and managing excess oil, but it does not directly treat acne or breakouts. A product of this type needs effective ingredients like niacinamide, propolis, or vitamin C to provide better skincare benefits for acne while controlling oil and keeping the skin clear.
Sources: [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/), [Journal of Cosmetic and Laser Therapy, 2013](https://pubmed.ncbi.nlm.nih.gov/23607739/)

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

Acetyl octapeptide-3, acetyl hexapeptide-8, rice starch, and betaine make this serum a fit by offering plumping and helping manage excess sebum. To work best for oily acne-prone skin, a product of this type needs effective ingredients like niacinamide, propolis, or vitamin C that actively target blemishes while maintaining a balanced, non-greasy feel.
Sources: [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/), [Journal of Cosmetic and Laser Therapy, 2013](https://pubmed.ncbi.nlm.nih.gov/23607739/)

### What does Acetyl Octapeptide-3 do for oily acne-prone skin?

Acetyl Octapeptide-3 helps smooth the look of expression lines and is generally gentle for oily, acne-prone skin. Because it targets fine lines rather than oil or breakouts, this type of product also needs oil-controlling ingredients like niacinamide to fully support clear skin.

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

Argireline is unlikely to treat acne or oiliness directly, as it focuses on reducing fine lines and making skin smooth. Oily acne-prone skin needs lightweight, non-greasy ingredients that clear pores and calm breakouts.
Sources: [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/), [Journal of Cosmetic and Laser Therapy, 2013](https://pubmed.ncbi.nlm.nih.gov/23607739/)

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

This treatment serum goes in your evening routine, applied after cleansing and before your moisturizer. Oily, acne-prone skin also needs products with targeted blemish-fighting ingredients and oil-balancing actives to properly manage breakouts.

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

Yes, you can use this serum with retinol by applying the serum first and following it with your retinol product. This routine helps manage excess oil while delivering active ingredients safely, though acne-prone skin ultimately needs targeted acne-fighting ingredients like salicylic acid or benzoyl peroxide to properly treat breakouts.

### How often should I use this serum?

You can use this treatment in the evening as part of your routine. Oily acne-prone skin needs a product of this type that also targets breakouts and blemishes with active ingredients like salicylic acid or benzoyl peroxide.

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

This serum is unlikely to clog pores or cause breakouts on oily acne-prone skin because the formula contains no harsh ingredients that typically cause irritation. However, it does not treat blemishes, so this skin type also needs targeted acne-fighting ingredients like salicylic acid or benzoyl peroxide for best results.
Sources: [Skin Research and Technology, 2003](https://pubmed.ncbi.nlm.nih.gov/12535284/)

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

Yes, it has no fragrance and no drying alcohol.
