Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate plumping for your oily skin due to acetyl octapeptide-3 and acetyl hexapeptide-8, while ingredients like rice starch and betaine help manage excess sebum and provide humectant action.
  • Glycerin and sodium hyaluronate offer general hydration benefits, though specialized ingredients to directly address oily shine are not prominent in this formula.
  • The product is safe for your oily skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

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 ExLinea Pro Peptide Serum work for oily skin?

PCA SKIN ExLinea Pro Peptide Serum works moderately well for oily skin, offering some plumping and hydration while helping to manage excess shine. However, treatments that rate higher for oily skin typically need ingredients like niacinamide, ferulic acid, and zinc PCA to better control oil production and refine pores.

American Journal of Clinical Dermatology, 2013Annals of Dermatology, 2019

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

Acetyl octapeptide-3, acetyl hexapeptide-8, rice starch, and betaine make this serum a fit for oily skin by offering moderate plumping and helping manage excess sebum. To fit oily skin even better, a treatment of this type needs ingredients like niacinamide and zinc PCA to actively control oil and manage shine.

American Journal of Clinical Dermatology, 2013Annals of Dermatology, 2019

What does Acetyl Octapeptide-3 do for oily skin?

Acetyl Octapeptide-3 is unlikely to directly improve oily skin, as it is typically used for its anti-wrinkle and firming benefits rather than oil control. Oily skin generally needs ingredients that regulate sebum production and reduce local inflammation to effectively manage shine and breakouts.

What does Argireline do for oily skin?

Argireline is generally safe for oily skin, but it is primarily used for anti-aging and smoothing wrinkles rather than controlling oil. To properly care for oily skin while targeting signs of aging, this type of product needs a lightweight, oil-free formula that hydrates without feeling heavy.

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

This treatment serum goes in the evening routine for oily skin, applied after cleansing and before your moisturizer. Treatments are placed at this step for simplicity and extra safety around sun exposure, though some may also be used in the morning or twice a day. To better fit oily skin, a product of this type needs specialized ingredients to directly address oily shine.

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

Yes, you can use this serum with retinol, applying this treatment after your retinol or hydrating products as part of your routine. This product is unlikely to cause irritation on oily skin, though an oily skin type needs specialized ingredients to directly control excess shine.

How often should I use this serum?

You can use this treatment in the evening as part of your routine. Oily skin works well with a product of this type when it includes ingredients that manage excess oil and keep the face balanced.

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

This serum is safe for your oily skin and is unlikely to cause irritation, breakouts, or clogged pores due to the absence of harsh ingredients. To properly care for oily skin, a product of this type needs dedicated oil-controlling and mattifying ingredients to manage excess shine effectively.

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
