How to Use RIMAN Collagen 100 Melting Mask

RIMAN WORLD July 2, 2026

RIMAN Collagen 100 Melting Mask is one of those products that can feel a little confusing the first time you open it.

It does not work like a regular wet sheet mask. It is not something you simply place on the face, wait 15 minutes, and remove. Instead, the collagen sheet is designed to melt into the skin after it is applied and activated with the right skincare step.

That is why the order matters.

If you use it correctly, the process is actually very simple: cleanse first, lightly prep the skin, apply the collagen sheets with dry hands, melt them with Dermatology Booster, then finish with serum and cream.

This guide explains the full routine in a clear, practical way.

Quick Answer

To use RIMAN Collagen 100 Melting Mask, start with clean skin. After cleansing, spray Two Phase Oil Mist over the face and wait until the skin feels slightly tacky. With completely dry hands, place the white collagen side directly onto the skin. Once the pieces are attached, remove the beige application sheet. Then spray Dermatology Booster generously until the collagen melts into the skin. Finish with Dermatology Serum, another layer of Booster, and Dermatology Cream.

The most important points are:

Keep your hands dry.

Apply the white collagen side onto the skin.

Use Two Phase Oil Mist before applying the mask.

Use Dermatology Booster after applying the mask.

Do not rinse it off.

What Is RIMAN Collagen 100 Melting Mask?

RIMAN Collagen 100 Melting Mask is a topical collagen mask in the RIMAN skincare range.

It is described as a fast-absorbing collagen mask that melts into the face. Unlike traditional sheet masks, this mask is made with delicate collagen sheets that are activated during the routine.

The product is positioned as a special treatment step rather than a daily basic skincare step.

In simple terms, it sits between cleansing and the finishing skincare steps. You use it after the skin is clean and lightly prepped, but before serum and cream.

Why It Feels Different from a Normal Sheet Mask

Most sheet masks are already soaked in essence. You unfold the mask, place it on the face, leave it on, and then remove it.

RIMAN Collagen 100 Melting Mask works differently.

The sheet itself is the treatment layer. It feels dry and delicate at first. Once placed on the face, it is activated with Dermatology Booster until it begins to soften and melt.

This is why many first-time users make small mistakes, such as applying it with wet hands, putting the wrong side down, or using too much mist before the sheet is in place.

Once you understand how the mask works, the routine becomes much easier.

What You Need Before You Start

For the full RIMAN routine, prepare these products:

RIMAN Collagen 100 Melting Mask

RIMAN Two Phase Oil Mist

RIMAN Dermatology Booster

RIMAN Dermatology Serum

RIMAN Dermatology Cream

You do not need to rush through the routine. It is better to take your time, especially when placing the collagen pieces on the skin.

The mask is thin, so careful handling makes a big difference.

Step 1: Start with Clean Skin

Begin with a clean face.

If you are wearing sunscreen, makeup, or heavier skincare, double cleansing is a good first step. A cleansing oil can help remove sunscreen and makeup, followed by a second cleanser to clean the skin more thoroughly.

Do not apply the collagen mask over makeup, sunscreen, or unwashed skin.

The mask works best when the skin is clean and ready for the next skincare steps.

Step 2: Prep with Two Phase Oil Mist

After cleansing, spray RIMAN Two Phase Oil Mist lightly over the face.

Then wait until your skin feels slightly tacky.

This part is important.

The face should not be dripping wet. If there is too much moisture, the collagen sheet may begin melting too early and become harder to position. If the skin is too dry, the sheet may not adhere well.

The goal is a light, slightly tacky surface.

Think of this step as preparing the skin so the collagen pieces can sit properly.

Step 3: Make Sure Your Hands Are Completely Dry

Before touching the collagen sheet, dry your hands carefully.

This is one of the most important parts of the routine.

The collagen sheet reacts to moisture. If your fingers are damp, the sheet may start to soften, fold, or melt before you place it on your face.

Dry hands give you more control.

If needed, keep a clean towel nearby and dry your fingertips again before handling the mask.

Step 4: Open the Mask and Remove the Clear Backing

Open one mask packet and gently take out the collagen pieces.

Each piece has a backing layer. Remove the clear plastic backing first.

Try to handle the pieces from the edges instead of pressing directly into the centre of the collagen sheet.

The sheet is delicate, but it is not difficult to use once you move slowly.

Step 5: Apply the White Side to the Skin

Place the white collagen side directly onto your face.

This is the treatment side.

You can apply the pieces to areas such as the cheeks, forehead, smile lines, chin, or neck. The placement does not have to be perfect. It depends on where you want to focus.

If a piece does not stick well, lightly mist the area again with Two Phase Oil Mist and try placing it again.

Do not over-spray. A little mist is enough.

Step 6: Remove the Beige Application Sheet

Once the collagen piece is attached to the face, gently peel off the beige application sheet.

After this step, the thin collagen layer should remain on the skin.

Peel slowly. If the collagen sheet starts lifting with the beige layer, press it back onto the skin and wait a moment before trying again.

This step is easier when the skin has been prepped correctly and the piece is already sitting flat.

Step 7: Spray Dermatology Booster to Melt the Mask

After the collagen sheets are in place, spray RIMAN Dermatology Booster generously over the mask.

This is the step that activates the collagen sheet.

The sheet will begin to soften and melt into the skin. You do not need to rub hard. Let the Booster do most of the work.

If needed, lightly press the area with your fingertips. The movement should be gentle.

Avoid scrubbing or dragging the skin.

Step 8: Apply Dermatology Serum

Once the collagen has melted and absorbed, apply Dermatology Serum.

Use a few drops and gently spread the serum over the face.

This step continues the skincare routine after the mask has been activated. The serum is usually used after the first Booster step in the RIMAN routine.

Step 9: Spray Booster Again

After the serum, spray Dermatology Booster again.

This follows the familiar RIMAN “Booster, Serum, Booster” layering method.

In this routine, the Booster has two roles. First, it helps melt the collagen mask. Then it works as part of the normal skincare layering step after serum.

Step 10: Finish with Dermatology Cream

Finish the routine with Dermatology Cream.

Apply a moderate amount and massage it gently over the face.

This final step helps complete the routine and leaves the skin feeling more comfortable and moisturized.

If you use the mask during the day, sunscreen should be the last step before makeup or sun exposure.

Simple Routine Order

Here is the easiest way to remember the order:

Cleanse

Two Phase Oil Mist

Collagen 100 Melting Mask

Dermatology Booster

Dermatology Serum

Dermatology Booster

Dermatology Cream

Sunscreen, if used during the day

The mask is not the final step. It should be followed with the rest of the skincare routine.

When Is the Best Time to Use It?

Many people use Collagen 100 Melting Mask in the evening because it fits well into a slower skincare routine.

It can also be used before a special event, especially when you want the skin to look more hydrated and smooth before makeup.

For regular skincare maintenance, once a week is a reasonable starting point.

Some users may use it more often before an event, but it is usually better to start slowly and see how the skin responds.

Can You Use It Every Day?

Most people do not need to use this mask every day.

It is better understood as a special treatment mask rather than a basic daily step.

If your skin is used to RIMAN products and responds well, you may choose to use it more frequently for a short period. But for many users, once a week is enough as a starting routine.

If your skin is sensitive, dry, reactive, or currently irritated, keep the routine simple and avoid overusing treatment products.

Can You Use It Without Dermatology Booster?

Dermatology Booster is an important part of this mask routine.

Two Phase Oil Mist helps prepare the skin and helps the mask adhere. Dermatology Booster helps activate and melt the collagen sheet.

So they are not doing the same job.

If you only use Two Phase Oil Mist, the mask may not melt in the intended way. If you skip the mist before application, the sheet may not stick as easily.

For the standard RIMAN method, use both:

Two Phase Oil Mist before applying the mask.

Dermatology Booster after applying the mask.

Can You Cut the Mask into Smaller Pieces?

Yes, the mask pieces can be adjusted.

Some users prefer to cut or place the pieces on specific areas, such as smile lines, forehead, under-eye area, cheeks, or neck.

This can be helpful if you want a more targeted routine.

Just remember that the sheet is delicate. Cut and handle it with dry hands, and avoid touching it too much.

Common Mistakes to Avoid

Applying the mask with wet hands

This is the most common mistake. Wet fingers can cause the collagen sheet to start melting before it reaches the face.

Making the face too wet

The skin should be slightly tacky, not soaked. Too much mist can make the mask harder to place.

Putting the wrong side down

The white collagen side should touch the skin. The beige sheet is only the application layer and should be removed after the mask is attached.

Rubbing too hard

Once the Booster is sprayed, let the mask melt gently. Press lightly if needed, but do not scrub.

Skipping the finishing cream

After the mask melts, continue with serum, Booster, and cream. The mask is part of the routine, not the whole routine.

Who Might Like This Mask?

RIMAN Collagen 100 Melting Mask may be suitable for people who enjoy special treatment steps in their skincare routine.

It may be especially interesting for users who are looking for:

A more hydrated-looking finish

A smoother-looking skin surface

A skincare step before makeup

A weekly treatment routine

A product that fits into the RIMAN Booster and Serum routine

It is not the simplest RIMAN product for beginners, but it is easy to understand once the steps are clear.

Who Should Be Careful?

Avoid using the mask on broken, irritated, sunburned, or damaged skin.

If you have very sensitive skin, a known allergy to marine-derived ingredients, or a history of reacting to collagen-based skincare products, patch testing is a sensible first step.

Collagen 100 Melting Mask vs Beauty Collagen EX

These two products can be easy to confuse because both are collagen-related.

They are not the same type of product.

Collagen 100 Melting Mask is a topical skincare mask applied directly to the face.

Beauty Collagen EX is a dietary supplement in the wellness category.

One is used on the skin. The other is taken internally as part of a beauty-from-within routine.

So when discussing RIMAN collagen products, it helps to separate topical skincare from wellness supplements.

Final Thoughts

RIMAN Collagen 100 Melting Mask is not difficult to use, but it does need the right order.

The key is to treat it differently from a normal sheet mask.

Start with clean skin. Use Two Phase Oil Mist to create a slightly tacky base. Keep your hands dry. Apply the white collagen side to the face. Remove the beige sheet. Then use Dermatology Booster to melt the collagen into the skin.

After that, finish the routine with Serum, Booster, and Cream.

Once you understand these steps, the mask becomes a simple treatment step within the wider RIMAN skincare routine.

FAQ

Do you wash off RIMAN Collagen 100 Melting Mask?

No. This is not a rinse-off mask. The collagen sheet is designed to melt into the skin after it is activated with Dermatology Booster.

Which side of the mask goes on the skin?

The white collagen side goes directly onto the skin. The beige application sheet should be removed after the piece is attached to the face.

Why is the mask melting too early?

Your hands or face may be too wet. Dry your hands completely and make sure the face is only slightly tacky before applying the sheet.

Why is the mask not sticking?

Your skin may be too dry. Lightly spray Two Phase Oil Mist first and wait until the skin feels slightly tacky.

Can I use Two Phase Oil Mist instead of Dermatology Booster?

They have different roles. Two Phase Oil Mist is used before the mask to help it adhere. Dermatology Booster is used after the mask is applied to help it melt.

How often should I use RIMAN Collagen 100 Melting Mask?

Once a week is a practical starting point for many users. Some people may use it more often before special occasions, depending on their skin tolerance.

Can I use it before makeup?

Yes, it can be used before makeup as part of a skincare routine. Let all products absorb fully before applying sunscreen or makeup.

Is it the same as Beauty Collagen EX?

No. Collagen 100 Melting Mask is a topical mask. Beauty Collagen EX is a wellness supplement.
