Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate wrinkle reduction for your normal skin, as acetyl octapeptide-3 and acetyl hexapeptide-8 work to plump and minimize fine lines, while glycerin and sodium hyaluronate provide general hydration.
  • While the peptides and humectants are well-suited for normal skin structure and hydration, they do not directly address your primary concerns of redness and irritation.
  • The product is safe for your sensitive skin, containing no harsh or prohibited ingredients that would cause irritation.

How to apply

  • Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
  • Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
  • Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
  • Always do a patch test before your first use and avoid getting the serum too close to your eyes .

Questions and answers

How well does ExLinea Pro Peptide Serum work for sensitive skin?

PCA SKIN ExLinea Pro Peptide Serum is an average fit for sensitive skin because while it provides hydration and helps smooth fine lines, it does not directly address redness and irritation. To better care for sensitive skin, a treatment of this type needs soothing and calming ingredients like niacinamide, antioxidants, and skin-repairing agents that reduce redness while keeping the skin comfortable.

Clinical, Cosmetic and Investigational Dermatology, 2017American Journal of Clinical Dermatology, 2013

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

Glycerin and sodium hyaluronate make this serum a good fit for sensitive skin by providing gentle hydration that is safe to use. Because other products fit sensitive skin better by calming redness and irritation, a treatment for this skin needs soothing ingredients like niacinamide or snail secretion filtrate alongside gentle hydrators.

Clinical, Cosmetic and Investigational Dermatology, 2017

What does Acetyl Octapeptide-3 do for sensitive skin?

Acetyl Octapeptide-3 is unlikely to irritate sensitive skin and may help soften expression lines by relaxing facial tension. To care for sensitive skin properly, this type of product needs soothing ingredients and a gentle, fragrance-free formula to keep your face calm and smooth.

What does Argireline do for sensitive skin?

Argireline is unlikely to cause irritation and is sometimes found in products designed to calm reactive skin. Studies show it helps smooth the look of wrinkles and decrease skin roughness when used consistently.

American Journal of Clinical Dermatology, 2013Pharmaceuticals, 2021

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

This treatment goes in the evening routine for sensitive skin, applied after the soothing toner and before the moisturizer. While it is safe for your sensitive skin and provides good hydration and wrinkle reduction with peptides and glycerin, it does not directly target redness and irritation. Sensitive skin needs gentle, calming ingredients like centella asiatica or green tea, along with barrier-repairing ceramides, to soothe irritation and keep redness under control.

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

You can use this serum with retinol by applying the serum first and following with your retinol once it is absorbed. While this product is safe for sensitive skin, it lacks ingredients that target redness and irritation, so a product for sensitive skin needs calming ingredients like centella asiatica or niacinamide to keep skin calm.

How often should I use this serum?

You can use this serum in your evening routine. Sensitive skin needs a treatment of this type to also include calming ingredients that soothe redness and irritation.

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

This serum is unlikely to clog pores or cause breakouts for sensitive skin, as it has a safe profile and contains no harsh or prohibited ingredients that trigger irritation. However, because it does not directly target redness and irritation, sensitive skin needs a product that also includes calming ingredients to soothe and protect the skin barrier.

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
