Lovi Assistant explains
- Offers moderate plumping for your combination skin due to acetyl octapeptide-3 and acetyl hexapeptide-8, which support skin structure and elasticity, while glycerin and betaine provide essential hydration.
- The formula also offers supportive benefits for acne, blemishes, and breakouts through glycerin and sodium hyaluronate, which hydrate the skin.
- The product is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use your serum as part of your PM routine and start 3x/week before working up to daily use.
- Apply this treatment after cleansing and toner, and before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
- Apply the product on clean, dry skin to help manage your breakouts safely.
- Avoid the eye area and do a patch test before your first use.

Questions and answers
How well does PCA SKIN ExLinea Pro Peptide Serum work for acne-prone skin?
PCA SKIN ExLinea Pro Peptide Serum works moderately well for acne-prone skin, providing hydration through glycerin and sodium hyaluronate while posing a low risk of irritation. However, an acne-prone product of this type needs effective ingredients like niacinamide, zinc PCA, and propolis to properly target breakouts and balance combination skin.
Which ingredients make this serum a good fit for acne-prone skin?
Glycerin and sodium hyaluronate make this serum a fit for acne-prone skin by providing gentle hydration. Treatments that rate higher for this skin type need ingredients like niacinamide, zinc PCA, or propolis to help balance oiliness and target breakouts.
What does Acetyl Octapeptide-3 do for acne-prone skin?
Acetyl Octapeptide-3 is unlikely to directly treat acne-prone skin, as breakouts are mainly driven by factors like oil production, inflammation, and hormones rather than expression lines. Products for acne-prone skin typically need ingredients that calm redness, clear pores, and balance oil.
What does Argireline do for acne-prone skin?
Argireline is not typically targeted for acne-prone skin, as it is primarily used to smooth fine lines and reduce wrinkles by relaxing facial movements. While it helps keep skin smooth, acne-prone skin generally needs ingredients that clear pores, calm redness, and balance oil production.
Where does this serum go in a skincare routine for acne-prone skin?
This serum goes in your evening routine after cleansing and before moisturizing, which keeps application simple and safe. Acne-prone skin works best with lightweight, oil-free hydrators and soothing ingredients like niacinamide or green tea.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying the treatment after cleansing and before your moisturizer in your evening routine, as it is unlikely to cause irritation. To fit acne-prone skin best, this type of product needs lightweight hydrators like glycerin and sodium hyaluronate to keep breakouts calm and comfortable.
How often should I use this serum?
You can use this treatment in the evening as part of your routine. This product of this type needs lightweight hydrators and gentle, non-irritating ingredients to keep acne-prone skin balanced and clear.
Can this serum clog pores, cause breakouts or purging for acne-prone skin?
This serum is unlikely to cause breakouts or clog pores on acne-prone skin because it avoids harsh ingredients and uses gentle hydrators like glycerin and sodium hyaluronate. However, because it provides only moderate hydration and plumping, acne-prone skin often does better with targeted blemish-fighting ingredients and lightweight hydrators that specifically balance oil production and calm irritation.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.

European Journal of Neurology, 2013Dissolving microneedles loaded with 3-O-ethyl ascorbic acid and acetyl hexapeptide-8 achieved higher cumulative transdermal delivery than aqueous solutions and significantly reduced photoaging signs while restoring oxidative balance in a UV/D-galactose-induced mouse model.
International Journal of Biological Macromolecules, 2026Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.
Journal of Drugs in Dermatology, 2011Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

BMC Oral Health, 2019Application of a cosmetic multiple emulsion containing vitamin C and wheat protein as well as a base formulation increased skin moisture in 11 human volunteers over four weeks, while producing no significant variations in skin sebum, pH, elasticity, melanin, or erythema.
Pakistan Journal of Pharmaceutical Sciences, 2008The addition of polymers and hydrolysed proteins to model body wash cosmetics improves foaming properties, storage stability, and safety by reducing skin irritant potential, with the polyvinylpyrrolidone/hydrolysed wheat protein crosspolymer showing the strongest reduction effect.
Colloids and Surfaces. B, Biointerfaces, 2015The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.
Journal of Cosmetic Dermatology, 2020Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.
International Journal of Cosmetic Science, 2001Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects.
