Triple Collagen Serum skin rejuvenating serum with triple collagen

💗 Triple Collagen Serum – a hydrating serum for plumper, more elastic and radiant skin

The medicube Triple Collagen Serum is a lightweight yet nourishing serum primarily developed for drier, dehydrated, dull and less elastic skin. The formula combines three key collagen forms – hydrolysed collagen, atelocollagen and soluble collagen – with niacinamide, various types of hyaluronic acid, trehalose and adenosine.

The serum’s aim is not just hydration: it helps to make the skin softer, smoother and plumper in appearance while supporting its natural radiance. It is a lighter alternative to richer collagen creams, making it easy to layer with other skincare products and suitable as a standalone hydrating and firming serum in your daily routine.

✨ What does it do?

• Intensely hydrates: glycerin, trehalose and various hyaluronic acids help to retain moisture, leaving the skin feeling softer and plumper.
• Supports a more elastic, firmer skin appearance: the three types of collagen and adenosine complement each other well to promote a smoother, more elastic look.
• Helps refine the appearance of fine lines emphasised by dryness: properly hydrated skin surface appears plumper and more even.
• Supports a more radiant complexion: the combination of niacinamide and hydrating ingredients helps to brighten and even out dull skin.
• Lightweight and easy to layer: its serum texture allows comfortable use under moisturisers or alongside other serums.
• Helps create a plump, hydrated “glass glow” effect: it does not give a shiny finish but supports the appearance of well-hydrated, smoother and naturally glowing skin.

🧬 Key ingredients

Triple Collagen Complex

The formula contains three key collagen forms: hydrolysed collagen, atelocollagen and soluble collagen.

Collagen used in skincare formulas primarily acts as a hydrating and skin-conditioning ingredient: it helps reduce dry, tight sensations and gives the skin a softer, smoother and plumper appearance.

Hyaluronic Acid Complex

The serum contains several hyaluronic acid derivatives, including sodium hyaluronate, hyaluronic acid, hydrolysed hyaluronic acid and sodium hyaluronate crosspolymer.

These moisture-binding ingredients help maintain skin hydration, making it feel more elastic, smoother and plumper.

Niacinamide

One of the most commonly used forms of vitamin B3 in skincare. It supports the skin’s natural protective barrier and hydration, contributing to a more even, fresher and radiant complexion.

Trehalose

A sugar molecule with strong moisture-binding properties that helps retain water on the skin’s surface. It is especially suitable for routines targeting dehydrated, tight or dull skin.

Adenosine

An ingredient frequently used in Korean skincare that supports a smoother, more elastic skin appearance, complementing the collagen formula’s focus on firmness and the appearance of fine lines.

🎯 Who is it recommended for?

Triple Collagen Serum may be a good choice if:

• your skin is dry or dehydrated,
• it looks duller or more tired,
• you want it to appear plumper and more elastic,
• fine lines have become more noticeable due to dryness,
• you are looking for a lightweight but nourishing hydrating serum,
• you want to support a naturally radiant, “glass skin” complexion,
• you want a serum that layers well under a richer moisturiser.

It is particularly suitable for normal, dry and combination skin. For very oily or easily weighed-down skin, it is advisable to start with a smaller amount as the formula is more nourishing than classic watery hydrating serums.

🧴 Texture and place in your routine

A light, silky serum that leaves the skin feeling hydrated and smoother.

After cleansing and toning, apply an appropriate amount to the face and gently pat into the skin. Follow with your moisturiser.

Suitable for use both morning and evening. It works especially well under Triple Collagen Cream 4.0 on drier skin, while it can be paired with lighter moisturisers on normal or combination skin.

According to medicube’s tip, it can be mixed in small amounts with other cosmetics if you want a smoother, more radiant base for makeup on drier skin.

💗 Why do we love it?

Because it is not a heavy “firming” serum but a well-layerable hydrating step that works simultaneously on plumper, smoother and more radiant skin appearance.

Alongside the three types of collagen, it contains various hyaluronic acids, niacinamide, trehalose and adenosine, resulting in a much more complex hydrating formula than the name might initially suggest.

It is especially a good choice when the skin does not necessarily require heavy creams but appears more dehydrated, duller or less elastic and you want to add an extra hydrating and radiance-boosting step to your routine.

❓ Q&A

What is the difference between Triple Collagen Serum and Triple Collagen Cream 4.0?

The Triple Collagen Serum is a lighter, layerable hydrating serum primarily aimed at supporting hydration, elasticity and a more radiant complexion.

Can it be used alongside Triple Collagen Toner?

Yes. The two products can be used in sequence: after cleansing, apply Triple Collagen Toner first, then Triple Collagen Serum. Finish with a moisturiser suitable for your skin type.

Can it be used morning and evening?

Yes. Triple Collagen Serum is designed for daily use and can be incorporated into both morning and evening routines.

Can it be used under makeup?

Yes. medicube specifically recommends it for use before makeup on drier skin. Allow it to absorb properly, then continue with moisturiser and daytime sunscreen; this helps create a smoother, more hydrated base.
