The INKEY List Collagen Peptide Serum 1.01 fl oz — Plumping & Firming Face Serum, Fragrance-Free

The INKEY List Collagen Peptide Serum is a lightweight peptide serum designed to visibly plump and firm skin while helping smooth the appearance of fine lines and wrinkles.

This concentrated face serum combines Matrixyl 3000 and Syn-Tacks Dual Peptide to support the look of firmer, more supple skin. Formulated without fragrance and suitable for all skin types, the formula layers easily into morning and evening routines to hydrate and refine skin texture. It’s cruelty-free and intended to complement hydrating and barrier-supporting steps like hyaluronic acid and ceramide moisturizers.

How does this serum help skin look plumper and firmer?

The serum uses targeted peptides that mimic some functions of natural collagen signaling to support a more voluminous skin appearance. Regular use can smooth the look of surface fine lines and create a bounce-to-the-touch effect when combined with hydrating base layers.

• Matrixyl 3000 peptide blend to promote smoother-looking texture.
• Syn-Tacks Dual Peptide for additional firming support.
• Light, fast-absorbing texture that layers under moisturizer and SPF.
• Fragrance-free to minimize irritation risk for sensitive skin.

When and how should I use the Collagen Peptide Serum?

Apply the serum after cleansing and your hydrating serums (like hyaluronic acid) both morning and evening for best results. Use a pea-sized amount, gently pat across face and neck, then follow with a moisturizer and, in the morning, an SPF product as the last step.

• AM/PM: after cleansing and hydration, before moisturizer.
• Amount: pea-sized—pat into face and neck, avoid rubbing harshly.
• Layer with hyaluronic acid first to boost hydration and absorption.
• Finish with sunscreen in the daytime for protection.

Is this serum suitable for sensitive or combination skin?

The formula is fragrance-free and created to be compatible with a broad range of skin types, including sensitive and combination skin. Because it’s lightweight and non-greasy, it integrates well into routines without overwhelming oily areas or leaving dry zones feeling tight.

• Fragrance-free and cruelty-free formulation.
• Light texture avoids pore-clogging or heavy residue.
• Works with both hydrating and barrier-repair moisturizers.
• Patch test recommended for highly reactive skin.

What results can I realistically expect, and how soon?

Visible changes in texture and the look of fine lines can appear over weeks with consistent use, though individual timelines vary based on skin condition and routine. The serum supports a plumper appearance rather than instant structural changes, so pairing it with hydration and daily protection yields the most noticeable outcomes.

• Short-term: improved surface hydration and smoother feel after initial applications.
• Medium-term: gradual reduction in the visibility of fine lines with regular use.
• Best when combined with hyaluronic acid and a barrier-support moisturizer.
• Use sunscreen daily to maintain and protect results.

Who is this for: The INKEY List Collagen Peptide Serum is tailored to anyone seeking a lightweight, peptide-forward serum to support firmer-looking skin and reduce the appearance of fine lines. It suits beginners and experienced skincare users alike, especially those who already use hydrating serums and want a peptide booster without fragrance. If you prefer fast-absorbing textures that layer well under moisturizer and SPF, this serum fits into both AM and PM routines as a targeted step to improve skin bounce and surface smoothness.
