How to Apply a Collagen Mask: Step-by-Step Guide

The short answer: on clean, bare skin, with no treatment underneath. Position the two parts of the mask, leave it on until it turns transparent, remove it without rinsing and massage in the remaining serum.

A hydrogel mask isn't applied like a sheet mask. Here is the complete method — and the mistakes behind most disappointments.

The 6 steps

1. Cleanse your face

Remove makeup thoroughly, then use a gentle cleanser. The skin must be perfectly clean: the serum won't get through makeup or sebum residue. Pat dry.

2. Apply nothing else

This is the most important step, and the one most often skipped.

No serum, no cream, no oil before the mask. A product applied underneath forms a film that slows penetration: you pay for 35 g of serum and let half of it through. The mask already contains everything it needs.

3. Open the sachet and separate the two parts

A hydrogel mask comes in two pieces: an upper part and a lower part. Gently remove the protective films. The gel is fragile — handle it without pulling.

4. Position it, taking your time

Upper part: forehead and cheeks, aligning the openings with your eyes.
Lower part: nose and chin.

Take thirty seconds to fit it properly. Smooth from the center outward to push out air bubbles, and let it follow the contours — sides of the nose, smile lines, jaw. A poorly positioned mask leaves areas untreated.

5. Leave it on until it turns transparent

Allow 4 hours, or all night. The mask gradually becomes transparent: that's the signal that it has delivered all of its serum.

You can go about your business, it stays in place. If you apply it before sleeping, do it at least an hour before bedtime.

6. Remove and massage in, without rinsing

Peel it off slowly, from bottom to top. Some serum will remain on the skin: massage it in with your fingertips, and it finishes absorbing within a few minutes.

Do not rinse. That would throw away half the product.

The 4 mistakes that ruin everything

Applying a treatment underneath. The big classic. It blocks penetration. Bare skin, always.

Removing it too early. A quarter of an hour is enough for a sheet mask, not for a hydrogel. At 20 minutes, you've only recovered a fraction of the serum.

Rinsing it off afterward. The remaining serum is the most concentrated part. It should stay on the skin.

Applying it on a beard. The gel doesn't adhere to hair, even three-day stubble.

What time of day?

In the evening, in most cases. Skin is more receptive at night, and four hours fit naturally into an evening or a night's sleep.

Before an event, apply it the evening before rather than the same day. The effect is at its peak a few hours after removal.

After a flight, it's the ideal moment. Cabin air often drops below 20% humidity — lower than the Sahara. Skin comes off the plane clearly dehydrated, and that's exactly what this type of mask makes up for.

How often?

Once a week.

Hydrolyzed collagen works by accumulation: a single session gives a lovely immediate effect, four consecutive weeks make the result last. That's why our masks are sold in fours — one box covers exactly one month of ritual.

Can it be combined with other treatments?

Before the mask: nothing, except cleansing.

After the mask: your usual routine, if you feel the need. Many people apply nothing, as the skin is already deeply hydrated.

On the same day as a peel or exfoliation: avoid. Leave at least 24 hours in between.

With a retinoid: alternate evenings. The mask can also help offset the discomfort of a retinol course.

Frequently asked questions

The mask slides, what should I do?
Check that the skin is thoroughly dry and that no treatment was applied beforehand. Smooth from the center outward as you place it, and wait a minute before moving.

Is it normal for it to turn transparent?
That's the expected result. Transparency means the serum has passed into the skin.

Can it be reused?
No. It is single-use.

Can it be used around the eyes?
The mask has eye openings and shouldn't be applied directly on the moving eyelid. It does, however, cover crow's feet.

Is it suitable for sensitive skin?
Yes. Our masks are dermatologically tested and suit all skin types.

Should it be stored in the fridge?
It isn't necessary, but a few minutes in the refrigerator before application gives a pleasant cooling sensation.
