If you're noticing your skin feels less firm or looks dehydrated, this serum offers a simple, effective hydration boost.

• What it is: A lightweight, watery serum formulated with 95% hydrolyzed marine (fish) collagen and adenosine.
• Who it's for: Ideal for those with normal, combination, dry, or dehydrated skin seeking to improve hydration and the appearance of fine lines and elasticity.
• What to expect: Skin feels immediately hydrated and plump. With consistent use, the complexion appears smoother and more supple.

1. Cleanser: Start with a clean face.
2. THIS PRODUCT: Apply 2-3 drops to your face and neck.
3. Sunscreen (AM) / Moisturiser (PM): Follow with your final step to seal in moisture and protect your skin.

Mindful Consumption Note: If you already have a hydrating serum, finish it before starting this one. Substitute, don’t stack similar products.

Minimalist (3 steps):

1. Cleanser
2. THIS PRODUCT (Marine Collagen Serum)
3. Sunscreen (SPF 30+)

Optional: Add a light moisturiser before sunscreen only if your skin feels tight or your sunscreen isn't hydrating enough for you.

Wait 30-60 seconds between serum and your next step.

Minimalist (3 steps):

1. Cleanser (use an oil cleanser first if removing makeup or water-resistant sunscreen)
2. THIS PRODUCT (Marine Collagen Serum)
3. Moisturiser

Optional: On nights you use a retinoid or strong acid, apply this serum first to buffer and hydrate the skin, potentially reducing irritation.

• Amount: 2-3 drops for the entire face and neck.
• Frequency: Can be used daily, both AM and PM.
• Method: After cleansing and toning, apply the drops to your skin and gently pat until absorbed. Follow with a moisturiser.

If-This / Then-That:

• If your skin is very dry: Layer this under a richer cream like the COSRX Advanced Snail 92 All In One Cream.
• If your skin is oily: This serum is lightweight enough to provide hydration without greasiness. You may find a light gel-cream is sufficient on top.
• If you use actives (Retinoids/Acids): Apply this serum first on clean, dry skin to provide a hydrating cushion before your active step.

This is a gentle hydrating serum suitable for daily use.

• Daily: Use AM and/or PM as part of your core routine.
• On Active Nights: It works well on nights you use exfoliants (AHA/BHA) or retinoids. Apply it before your active to hydrate and buffer the skin.

• Immediate: Skin feels instantly hydrated, soothed, and looks plumper.
• 2–4 Weeks: Skin texture may feel smoother and more supple as hydration levels are consistently maintained.
• 4–8+ Weeks: With consistent use alongside daily sunscreen, the appearance of fine dehydration lines may be reduced. Skin feels firmer and looks dewier.

Myth: "Applying collagen to your skin will replace the collagen you've lost."

Reality (Why This Instead): Topical collagen molecules are generally too large to penetrate into the dermis to rebuild your skin's structure. However, hydrolyzed collagen, like the 95% concentration in this serum, is an excellent humectant. It draws and holds moisture on the skin's surface, providing intense hydration that plumps up the skin, smooths the look of fine lines, and gives a dewy, firm appearance. Think of it as a powerful hydrator, not a structural replacement. (Ingredient Rationale)

This serum is a versatile team player and layers well with most ingredients.

• Works Well With: Vitamin C, Niacinamide, Retinoids (Retinal/Retinol), Hyaluronic Acid, and exfoliating acids (AHA/BHA). It can help hydrate and soothe the skin, reducing potential irritation from stronger actives.
• Use Carefully With: No major conflicts. Just follow the thinnest-to-thickest texture rule in your routine.
• Avoid On: Do not apply to broken or irritated skin without patch testing.

• Excellent for: Dry, Dehydrated, Normal, Combination, Mature skin.
• Good for: Oily skin (as a lightweight hydrator), Sensitive skin (as it is fragrance-free and has a minimal formula).
• Caution: While rare, those with fish allergies should patch test carefully. One reviewer with combination skin noted clogged pores, so as with any product, individual responses can vary.

• Dehydration and dryness
• Loss of skin firmness and elasticity
• Appearance of fine lines and wrinkles
• Dull or rough skin texture

• Functional Ingredient: Adenosine. The Ministry of Food and Drug Safety (MFDS) in South Korea recognizes Adenosine as an effective ingredient for helping to reduce the appearance of wrinkles.

Key Ingredients Explained:

Who should use with caution: Individuals with a known allergy to fish or fish products should perform a patch test before using this serum.

Patch Test Protocol:

1. Apply a pea-sized amount to a clean patch of skin on your jawline or behind your ear.
2. Wait 24 hours. If any redness, itching, or irritation occurs, do not use the product.
3. If no reaction occurs, re-check at 48 and 72 hours before applying to your full face.

Discontinue use immediately if a rash or burning sensation develops.

• Texture: A very lightweight, clear, watery gel.
• Finish: Absorbs quickly into the skin leaving a hydrated, slightly dewy finish with no sticky or greasy residue.
• pH: Not publicly disclosed by the brand, but expected to be in a skin-friendly range of ~5.5 - 6.5.
• Fungal Acne (Malassezia) Compatibility: The ingredient list appears to be free from common fungal acne triggers.

• Issue: Clogged pores or breakouts.
  Solution: While the formula is lightweight, a small number of users with combination or oily skin have reported clogging. Ensure you are double cleansing thoroughly at night to remove all impurities. If breakouts persist, this serum may not be the right fit for your skin type.
• Issue: Not seeing results for wrinkles.
  Solution: This serum is primarily for hydration and improving the appearance of fine dehydration lines. For deeper, structural wrinkles, consider incorporating a product with retinoids, like the Beauty of Joseon Revive Eye Serum (which can be used on the face). Results from any product take time and require consistent daily use of sunscreen.

The lightweight, non-sticky texture of this serum makes it an excellent choice for the hot and humid climate in Mauritius.

• Humid Summer: It provides essential hydration without feeling heavy or contributing to greasiness. For very oily skin types, it might be enough hydration under sunscreen in the morning.
• Drier Winter/AC Exposure: It layers beautifully under a moisturiser to provide an extra boost of hydration against the drying effects of air conditioning or less humid weather.

Aggregated sentiment from online beauty communities suggests this is a well-liked serum for hydration, though results for significant anti-aging are modest.

• "I've been using it for a few weeks and I absolutely love it. I have oily, dehydrated skin, sensitive and probably rosacea. It hasn't irritated my skin at all, and feels really hydrating and plumping." — Reddit, r/AsianBeauty review (2025-XX)
• One user on YesStyle with dry skin, aged 35-44, simply rated it 5 stars, commenting it's a "very good serum for daily use." (YesStyle Review, 2025-XX)
• A fair caveat from another user: "The Peptide and Marine Collagen just don't quite do anything any which way... I decided after a while that they really aren't anything special." This user felt it was hydrating but didn't see significant changes after 8-10 months of use. — Reddit, r/AsianBeauty review (2024-XX)

Is this serum sticky?

No, it has a very lightweight, watery texture that absorbs quickly without any tackiness.

Is this product vegan?

No, the hydrolyzed collagen is derived from fish, making it unsuitable for vegans.

Can I use the Marine Collagen Serum with Vitamin C?

Yes, absolutely. They are compatible. You can apply your Vitamin C serum first, let it absorb, and then layer the Marine Collagen Serum on top for added hydration.

Will this get rid of my deep wrinkles?

This serum is excellent for hydrating the skin and plumping the appearance of fine lines caused by dehydration. For deeper, more established wrinkles, a product containing a retinoid (like retinal or retinol) would be a more effective choice.

• Best For: Individuals looking for a simple, lightweight serum to boost hydration, plump the skin, and improve the feeling of firmness.
• Key Benefits: Provides immediate and lasting hydration with a non-sticky finish. Minimalist, fragrance-free formula is suitable for sensitive skin. Contains MFDS-approved adenosine for anti-wrinkle benefits.
• Keep in Mind: It is not a vegan product. While it helps with the appearance of fine dehydration lines, it may not be potent enough for deep, structural wrinkles.
