Marine or plant-based collagen? What each does on the skin and how to choose the right one for your routine.
Plant-Based vs Marine Collagen in Skincare: What's the Difference?
Nov 14, 2026
Collagen is one of the most searched ingredients in skincare. Today you will find two main types on labels: marine collagen and plant-based collagen. Here is what each one is, what it does on the skin and how to choose.
What collagen does in skincare
Collagen is a protein that gives skin its structure. In creams and serums, collagen and collagen-like ingredients mainly work on the surface: they help hold moisture and leave a smooth, soft film, so skin looks plumper and fine lines look softer. For results you can see, hydration and consistent daily use matter most.
Marine collagen
Marine collagen comes from fish. It is valued for its moisturizing, film-forming properties and is often paired with Hyaluronic Acid and marine elastin. You will find it in Italian formulas from Verdeoasi Milano and Dr. Kraut Milano, such as day creams, cleansing milks and hydrating gel masks.
Plant-based collagen
Plant-based collagen is a vegan alternative made from plant proteins or peptides chosen to support the skin in a similar way. It suits people who avoid animal-derived ingredients. The Equilibra Plant-Based Collagen line from Italy combines it with Vitamin C and Pro-Vitamin B5 in a lifting serum, a replumping cream and an eye contour cream.
Which one should you choose?
- Choose plant-based if you prefer vegan formulas or have a fish allergy.
- Choose marine if you like rich, cushiony textures and have no dietary or ethical concerns.
- Look at the whole formula. Hyaluronic Acid, peptides and antioxidants such as Vitamin C often make as much difference as the collagen itself.
A simple collagen routine
- Cleanse gently, morning and evening.
- Apply a collagen or peptide serum on slightly damp skin.
- Follow with a cream to help lock in moisture, and an eye contour cream if you wish.
- In the morning, finish with sunscreen.
Frequently asked questions
Does collagen in a cream replace the skin's own collagen?
No. Collagen in skincare works mainly on the skin's surface, helping it hold moisture so it looks smoother and plumper.
Is plant-based collagen vegan?
Plant-based collagen is made without animal sources. Check the brand's label or vegan certification if the whole product needs to be vegan.
Can I use collagen skincare with Vitamin C or retinal?
Yes, collagen-based products are generally easy to combine. Introduce one new product at a time and follow each product's directions.
When will I see results?
Skin can feel softer and look more hydrated soon after application. For a smoother-looking complexion, use your routine consistently for several weeks.
