Collagen Serum
Collagen Serum
Product Description
Product overview
PUCA – Pure & Care Collagen Serum is a lightweight, fast-absorbing anti-ageing serum built around soluble hydrolyzed collagen, sodium hyaluronate and skin-identical amino acids. Formulated by the Danish brand PUCA – Pure & Care, this 30ml fragrance-free serum is designed to flood skin with moisture, support firmness and elasticity, and visibly soften fine lines — all in a gentle, dermatologically tested formula suitable even for sensitive skin.
Multi-Layer Hydration
Sodium hyaluronate, glycerin and hydrolyzed collagen work together as humectants to attract and hold water in the upper skin layers for a plumper, smoother look.
Texture & feel
SENSORYMulti-Layer Hydration
Sodium hyaluronate, glycerin and hydrolyzed collagen work together as humectants to attract and hold water in the upper skin layers for a plumper, smoother look.
Firmness & Elasticity
A high content of soluble collagen and skin-identical amino acids targets the appearance of fine lines, helping skin look more even, firmer and supple over time.
Barrier Support
Corn gluten amino acids, beta-glucan and glycosphingolipids reinforce the skin's natural moisture barrier and help calm and soothe.
Gentle & Clean
Fragrance-free, alcohol-free and silicone-free, with proDERM dermatological testing showing very good tolerability — even on sensitive, allergy-prone skin.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone or chemical sunscreens — the formula is built from hydrators and amino acids generally considered low-risk. Always confirm with your doctor.
Independently verified as malassezia-safe — no problematic fatty acids, esters, polysorbates or ferments that typically feed fungal acne.
proDERM patch testing on subjects including sensitive, atopic and allergy-prone skin showed no adverse reactions and "very good" tolerability.
A hydrating base layer that pairs comfortably with vitamin C, niacinamide, retinol or exfoliating acids — apply this before richer creams.
Contains phenoxyethanol and glycols (butylene/dipropylene/hexylene). Well tolerated by most, but very reactive skin should patch test first.
No animal-derived ingredients or testing, and free from reef-harming UV filters. Rated "A" (green) by Denmark's Kemiluppen / Think Chemistry.
Ingredient breakdown
INGREDIENTSHydrolyzed Collagen 3rd in list*Promising
The star of the formula and the 3rd-listed ingredient. Hydrolyzed collagen is collagen broken into smaller peptides that act as humectants and emollients, drawing in water and forming a light moisture-sealing layer for softer, plumper-looking skin.
- Function: Hydration, smoothing and surface conditioning.
- Research: A 2021 study of 1,125 participants linked collagen supplementation to improved elasticity and wrinkle appearance, though topical vs. oral effects are still debated.
Sodium Hyaluronate ~0.5–1%*Proven
The salt form of hyaluronic acid and one of the most reliable hydrators in skincare. It binds large amounts of water at the skin's surface for an immediate plumping, dewy effect that softens the look of fine lines.
- Function: Humectant that improves moisture retention and surface hydration.
- Source: Naturally present in skin; here it works alongside glycerin and collagen for layered hydration.
Corn Gluten Amino Acids 4th in list*Promising
Amino acids are natural moisturising factors (NMFs) found in skin. PUCA highlights this ingredient for supporting barrier function and helping skin feel moisturised, soothed and smooth.
- Function: Barrier support and NMF replenishment.
- Why it matters: A healthy barrier holds moisture better and is more resilient to irritation.
Beta-Glucan Soothing*Proven
A polysaccharide derived from oats, yeast or fungi that hydrates, calms and boosts the skin's natural barrier. It also acts as an antioxidant to help defend against free-radical stress.
- Function: Soothing, hydrating and antioxidant support.
- Research: Studies suggest it can penetrate skin and support wound healing and the look of wrinkles.
Portulaca Oleracea (Purslane) Extract Botanical*Promising
A traditional Korean medicinal succulent rich in omega-3 fatty acids, NMFs, vitamins and antioxidants. Valued for its anti-inflammatory, antioxidant and skin-soothing properties.
- Function: Calming and antioxidant botanical.
- Bonus: Works with prickly pear (Opuntia) and beta-glucan to reinforce the formula's soothing profile.
Morus Alba Root Extract Brightening*Promising
White mulberry root extract, traditionally used to help even and brighten the look of skin tone, supporting the serum's overall radiance-focused profile.
- Function: Tone-evening / brightening botanical.
- Note: Evidence is promising but concentration-dependent; expect gradual rather than dramatic results.

Where it fits in your routine
ROUTINEApply onto clean skin before heavier creams. As a hydrating layer it slots in early in your routine, AM and PM, and locks in best when sealed with a moisturiser.
How to use
HOW TO USECleanse
Wash your face thoroughly and pat dry, leaving skin slightly damp for better absorption.
Tone (Optional)
Follow with a hydrating toner or essence if it's part of your routine.
Apply 3–4 Drops
Dispense 3–4 drops onto the face and neck, avoiding the immediate eye area.
Massage In
Gently massage until the serum is fully absorbed — it sinks in within about 30 seconds.
Seal & Protect
Lock in hydration with a moisturiser. In the morning, always finish with SPF.
Who is it for?
WHOPerfect for you if:
- Your skin feels dry, tired or dehydrated and needs a moisture boost
- You're starting to notice early fine lines and loss of bounce
- You have sensitive or reactive skin and want a fragrance-free formula
- You're fungal-acne prone and need a malassezia-safe serum
- You prefer vegan, cruelty-free and reef-safe skincare
- You want an affordable, lightweight everyday hydrator
Consider alternatives if:
- You expect a serum to "erase" deep wrinkles overnight
- You want clinically high, clearly disclosed active percentages
- You're after a treatment serum (retinol, acids, vitamin C) instead of hydration
- You prefer rich, cushiony cream textures over watery serums
- You need a large-size bottle (this is a compact 30ml)
Skin type compatibility

Balances hydration across drier and oilier zones without congesting the T-zone.
Fragrance- and alcohol-free with proDERM-tested "very good" tolerability, even on allergy-prone skin.
Supports firmness and plumpness through hydration; pair with retinol or peptides for stronger anti-ageing.

REVIEWSPros & cons
BALANCEDPraised
- Gentle, fragrance- and alcohol-free formula
- Dermatologically tested with "very good" tolerability on sensitive skin
- Lightweight and fast-absorbing with a dewy, non-greasy finish
- Layered hydration from collagen, HA, glycerin and amino acids
- Vegan, cruelty-free, reef-safe and fungal-acne safe
- Affordable for an everyday hydrating serum
Criticized
- Exact active percentages aren't disclosed by the brand
- Topical collagen mainly hydrates rather than rebuilding collagen
- Compact 30ml size only
- Limited independent / mass-retailer reviews
- Not a substitute for stronger anti-ageing actives like retinoids
Budget-friendly alternatives (dupes)
DUPESPer SkinSort's matching, both are hyaluronic-acid serums that are fungal-acne and reef safe, sharing about 7 ingredients. Adds a subtle glow-priming finish but lacks the collagen and amino-acid focus.
A cruelty-free HA serum sharing around 6 ingredients and the same clean, allergen-free, fragrance-free profile. Simpler hydration play without the collagen and botanical extracts.
SkinSort's top community-liked dupe. Centres on mineralising water plus HA in a larger 50ml size; pricier and without the soluble collagen of the PUCA serum.

Frequently asked questions
FAQThe formula contains no retinoids, salicylic acid, hydroquinone or chemical sunscreen filters — the ingredients are hydrators, amino acids and soothing botanicals generally considered low-risk during pregnancy and breastfeeding. That said, no skincare brand can guarantee individual safety, so always confirm with your doctor or midwife before adding new products during pregnancy or nursing.
Yes. It has been independently verified as fungal-acne (malassezia) safe. It avoids the fatty acids, esters, polysorbates and fermented ingredients that typically trigger malassezia, making it a sensible choice if you're prone to fungal acne.
Yes. This is a gentle, hydrating serum with no active acids or vitamin C of its own, so it layers well with most actives. Apply it as a hydrating base before or after your treatment serum. Pairing it with retinol or exfoliating acids can actually help offset dryness. Introduce strong actives gradually and always wear SPF during the day.
It suits most skin types and performs especially well on oily, combination, sensitive and acne-prone skin thanks to its lightweight, oil-free, fragrance-free formula. Dry and mature skin will also benefit from the hydration but should layer a richer moisturiser on top for lasting comfort.
Hydration and softness are usually noticeable immediately. Smoother texture and a dewier look tend to appear within 1–2 weeks of daily use. Firmness and elasticity changes happen in deeper skin layers and take longer — expect to use it consistently for around 6–12 weeks for the best visible results.
After cleansing (and toning, if you tone), apply 3–4 drops to the face and neck before heavier creams. As a lightweight hydrating layer it goes on early in the routine, both morning and night, and is then sealed in with a moisturiser. In the morning, finish with SPF.
It's very unlikely to clog pores. The formula is water-based, oil-free and built around humectants, with an estimated comedogenic rating of around 1 out of 5. There are no heavy oils or pore-clogging ingredients, which is why it works well for acne-prone and congestion-prone skin.
Around 12 months after opening, in line with the period-after-opening (PAO) symbol on the packaging. Store it in a cool, dry place out of direct sunlight and keep the dropper clean to help it last its full shelf life.
Verdict: PUCA – Pure & Care Collagen Serum is a gentle, well-formulated everyday hydrator that punches above its affordable price. The blend of hydrolyzed collagen, hyaluronic acid, amino acids and soothing botanicals delivers reliable hydration, a smoother surface and a dewy, non-greasy finish, backed by dermatological testing that shows very good tolerability even on sensitive skin. It loses half a star for undisclosed active percentages and the realistic limits of topical collagen — this is hydration and barrier support rather than a deep-wrinkle treatment. If you want a clean, fragrance-free, fungal-acne-safe serum to layer under your moisturiser or alongside stronger actives, it's an easy, low-risk recommendation.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
