It's 6 PM. You have dinner at 10 PM and an end-of-day tired look. Good news: you have exactly the time you need. Four hours. That's the promise – kept – of SAMPAR's Hydrafuse Collagen 4H Mask: the Korean ritual that transforms tired skin into plumped, smoothed, and radiant skin, in the time it takes for a nice bath.

The mask that becomes transparent

Forget the dripping sheet mask. The Hydrafuse is a two-part bio-collagen hydrogel that perfectly molds to the face and releases the equivalent of 30 ml of serum directly onto your skin. Its special feature: it becomes transparent when your skin has absorbed everything. Opaque at first, clear at the end: you see the exact moment the treatment has finished its work.

Leave it on for 4 hours for an express glow boost, or overnight for a more intense treatment.

The secret: collagen under 100 daltons

Everyone puts "collagen" on their packaging. But collagen is a large molecule: a standard collagen weighs several hundreds of thousands of daltons, far too heavy to pass through the skin's surface. It just stays on top.

SAMPAR has chosen a very low molecular weight collagen, under 100 daltons – one of the finest on the market, far ahead of competing bio-collagen masks (often around 240 Da). At this size, collagen penetrates the stratum corneum instead of remaining on the surface, and acts as a moisturizing and film-forming agent that retains water and visibly plumps up the skin. Finer = better absorbed = plumper skin.

Up to +31% hydration in 4 hours

SAMPAR's promise is "Be beautiful without waiting". With Hydrafuse, it shows:

• Up to +31% hydration in just 4 hours
• Visibly plumped skin, smoothed features, reduced dehydration fine lines
• Visibly tightened pores, refined skin texture
• Boosted radiance, the "glass skin" effect
• No rinsing required: just massage in the excess serum, and you're done

A formula designed for glow

• Hyaluronic Acid – the star moisturizer, which retains water and creates a protective film for supple and comfortable skin.
• Niacinamide – refines skin texture, tightens the appearance of pores, and helps even out skin tone.
• Vitamin C – a radiant antioxidant that helps revive dull skin.
• Low molecular weight collagen water – the hydrating and plumping agent that gives the mask its name.
• Adenosine & Red Algae Extract – to soothe and support visibly smoother skin.

The best of Korean routine, formulated with French precision. Suitable for all skin types.

The perfect ritual

1. Cleanse your face. Apply to clean skin, without cream on top.
2. Open the sachet, unfold the two parts and remove the soft film to reveal the soaked side.
3. Apply the serum side against the skin and adjust to your face.
4. Wait 4 hours (or overnight).
5. Remove when the mask becomes transparent, then massage the remaining serum. No rinsing.

Please note: the mask does not adhere to beards. For the lower part of the face, prefer hairless skin.

Frequently Asked Questions

Is the mask reusable?
No. The hydrogel completely dehydrates by releasing its active ingredients: once transparent, it has given its best.

How many times a week?
Once a week for maintenance. For an intensive cure, several times in the same week.

Is it suitable for sensitive skin?
Yes, it is formulated for all skin types. If in doubt, test in the crook of your elbow 48 hours beforehand.

4 hours or overnight?
Both: 4 hours for an express glow, overnight for more intense hydration upon waking.
