Ingredient breakdown

INGREDIENTS

Matrixyl 3000™ 1%Proven

A trademarked peptide complex combining Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7. Works by mimicking collagen breakdown signals, triggering skin to produce new collagen for firmer, smoother skin.

  • Mechanism: Acts as a signal peptide (matrikine) that tells skin to boost collagen production
  • Research: Manufacturer studies show up to 39.4% reduction in deep wrinkles after 2 months of twice-daily use
  • Synergy: The two peptides work together - one stimulates collagen, the other reduces inflammation
Most studied and widely used anti-aging peptide complex in modern skincare

Syn-Tacks™ Dual Peptide ~0.5%Promising

Contains Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine and Palmitoyl Dipeptide-5 Diaminohydroxybutyrate. Provides additional collagen-boosting benefits and supports skin matrix proteins.

  • Function: Helps stimulate production of collagen, fibronectin, elastin, and laminin
  • Benefit: Supports skin's structural integrity for improved firmness and bounce
  • Complementary: Works synergistically with Matrixyl 3000 for enhanced results

Hyaluronic Acid ~1%Proven

A powerful humectant that can hold up to 1000x its weight in water. Provides immediate hydration and plumping while helping other actives penetrate more effectively.

  • Hydration: Attracts and binds water to the skin's surface for instant plumping
  • Delivery System: Helps carry peptides deeper into the skin
  • Skin Barrier: Supports moisture retention and skin barrier function

Glycerin ~4-5%Proven

A classic humectant and skin-identical ingredient that helps maintain skin's natural moisture balance. Non-comedogenic and well-tolerated by all skin types.

  • Moisturization: Draws water into the skin, keeping it hydrated throughout the day
  • Skin Barrier: Helps maintain the lipid barrier in a healthy state
  • Safety: Comedogenic rating of 0, safe for acne-prone skin

Leuconostoc/Radish Root Ferment FiltrateSupporting

A natural preservative alternative derived from fermented radish root. Provides antimicrobial properties while being gentle on skin.

  • Function: Natural preservation system to maintain product freshness
  • Benefit: Gentler alternative to traditional preservatives

How to use

HOW TO USE
1

Cleanse Your Skin

Start with clean skin. Use your preferred cleanser to remove makeup, sunscreen, and impurities.

2

Apply to Damp Skin

For best absorption, apply to slightly damp skin after toner or hydrating essence. This helps lock in moisture.

3

Use a Pea-Sized Amount

Dispense a pea-sized amount onto fingertips. A little goes a long way - too much may cause pilling.

4

Gently Tap Into Skin

Use fingertips to gently tap and press the serum into face and neck. Avoid rubbing to maximize absorption.

5

Follow with Moisturizer

Wait 30-60 seconds for absorption, then seal with your moisturizer. Always finish with SPF in the morning.

06

Who is it for?

WHO

Perfect for you if:

  • You're in your mid-20s+ and want to prevent early signs of aging
  • You have fine lines or loss of skin firmness
  • You want a gentle alternative to retinol
  • You're pregnant or breastfeeding and need pregnancy-safe anti-aging
  • You prefer lightweight, non-greasy serums
  • You want an affordable entry into peptide skincare
  • You have sensitive skin that reacts to stronger actives

  • You want higher peptide concentrations (try The Ordinary Matrixyl 10%)
  • You need more comprehensive anti-aging (consider adding retinol)
  • You prefer richer, more nourishing textures
  • You're looking for deep wrinkle treatment (may need stronger actives)

Frequently asked questions

FAQ

Yes, The INKEY List Collagen Booster is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or other ingredients typically avoided during pregnancy. The formula relies on peptides (Matrixyl 3000, Syn-Tacks) and hyaluronic acid, all of which are considered safe for topical use during pregnancy. Space NK specifically lists this product as "safe for use when pregnant or breastfeeding."

No, this product is NOT fungal acne safe. It contains Polysorbate 20 and palmitoyl peptides (which contain palmitic acid), both of which can potentially feed malassezia yeast. Additionally, it contains Leuconostoc/Radish Root Ferment Filtrate, which may be a concern for those with fungal acne sensitivities. If you have fungal acne or pityrosporum folliculitis, consider fungal acne-safe alternatives.

Yes, peptides generally play well with most other actives. The INKEY List states this product "layers well with all actives, AM or PM" and specifically works well with Retinol, Bakuchiol, Hyaluronic Acid, Q10, and their Hepta Peptide. However, for optimal peptide efficacy, avoid using direct acids (like glycolic or salicylic) in the same routine as low pH can reduce peptide benefits. Use acids in your PM routine and peptides in your AM routine, or alternate days.

This serum is suitable for all skin types including normal, dry, oily, combination, and sensitive skin. Its lightweight, watery texture makes it particularly excellent for oily and combination skin as it absorbs quickly without adding shine. For dry skin, it provides good hydration but should be followed with a richer moisturizer. Sensitive skin types benefit from its fragrance-free, gentle formula. The only exception is fungal acne-prone skin, which should avoid this product.

According to the brand, visible results can be expected in up to 6 weeks with consistent use. You'll notice immediate hydration benefits, with smoother skin texture appearing within 1-2 weeks. Firmness improvements typically begin around weeks 3-4. Peptides work on accumulation, meaning the longer you use them, the better the results. For optimal anti-aging benefits, continue use for 2-3 months. Be consistent and use AM and PM - but don't overuse, as more isn't necessarily better.

Apply this serum after cleansing and toning, following the thinnest-to-thickest rule. The recommended order is: 1) Cleanser, 2) Toner, 3) Hyaluronic Acid Serum (if using), 4) Collagen Booster, 5) Other serums/treatments, 6) Eye cream, 7) Moisturizer, 8) SPF (AM only). Apply to slightly damp skin for best absorption. Wait about 30-60 seconds between products to avoid pilling.

No, this product has a low comedogenic rating of approximately 1 out of 5. The formula is oil-free and contains no heavy pore-clogging ingredients. Key ingredients like glycerin (comedogenic rating 0), hyaluronic acid (rating 0), and the peptide complexes are all considered non-comedogenic. However, if your skin is very acne-prone, always patch test new products and introduce them gradually into your routine.

The Period After Opening (PAO) is 12 months. The 30ml bottle typically lasts about 1 month with twice-daily use (AM and PM) using the recommended pea-sized amount. Store in a cool, dry place away from direct sunlight. The press-button cap helps maintain product integrity. While refrigeration isn't required, it can help extend freshness, especially in warm climates.

— Skincarisma verdict
4.2 / 5 ★★★★☆

Verdict: The INKEY List Collagen Booster is an excellent entry-level peptide serum that delivers solid hydration and gentle anti-aging benefits at an unbeatable price point. While its 1% Matrixyl concentration is lower than competitors like The Ordinary's 10% formula, the addition of Syn-Tacks dual peptide and its pregnancy-safe, fragrance-free formulation make it a smart choice for skincare beginners, sensitive skin types, and those seeking preventative anti-aging. Just manage expectations - this is a gradual, long-term player rather than a quick-fix solution. For deeper wrinkles or more aggressive anti-aging, consider combining with retinol or upgrading to higher-concentration peptide serums.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
