Dr.Jart+ Cryo Rubber with Brightening Vitamin C

Product Overview

A two-step brightening treatment designed for dullness, uneven-looking skin tone, loss of radiance and visible discolouration.

The treatment combines a concentrated brightening ampoule with a cooling rubber mask placed over the top. The ampoule contains niacinamide and 3-O-ethyl ascorbic acid, a stable vitamin C derivative, together with antioxidant botanical extracts and moisturising ingredients.

The rubber mask contains hydrating and soothing ingredients including glycerin, panthenol, allantoin and dipotassium glycyrrhizate and helps hold the treatment against the skin.

Within the Glass Ritual Pigmentation Collection, this is an occasional brightening treatment, rather than an everyday pigmentation serum.

Why We Chose It

We chose this treatment because it offers something genuinely different from another bottle of serum.

The two-step system combines a leave-on ampoule containing niacinamide + vitamin C derivative with an occlusive cooling mask that creates a dedicated treatment experience.

Niacinamide appears high in the ampoule ingredient list, while 3-O-ethyl ascorbic acid provides targeted antioxidant and brightening support.

The formula also includes turmeric, vitamin E and several botanical extracts alongside moisturising ingredients.

This makes it particularly useful as an occasional radiance treatment within an established pigmentation routine.

• Helps improve the appearance of visible discolouration
• Contains niacinamide

Who It's For

Consider this treatment if you are concerned about:

• Dullness
• Uneven-looking skin tone
• Loss of radiance
• Visible discolouration
• Dehydrated-looking skin
• Wanting occasional vitamin C care
• Wanting a treatment-mask experience rather than another daily serum

It is particularly appropriate for someone who already has a simple daily pigmentation routine and wants an occasional supplementary treatment.

How to Use

This is a two-step treatment.

Apply the brightening ampoule evenly over freshly cleansed skin.

Place the rubber mask over the face, positioning it carefully so it sits comfortably against the skin.

Leave on according to the directions supplied with the product.

Remove the rubber mask and gently massage or pat the remaining ampoule into the skin.

Follow with moisturiser if required.

Ritual Position

Cleanse → Tone if desired → Brightening Ampoule → Cryo Rubber Mask → Moisturise if needed

Use as an occasional treatment step within your Glass Ritual.

Glass Ritual Pairing

Because the ampoule already contains niacinamide + vitamin C derivative, there is no need to deliberately combine the treatment with another strong vitamin C serum during the same session.

A simple treatment ritual may be:

Gentle Cleanser → Cryo Rubber Brightening Treatment → Moisturiser

If you use exfoliating acids, retinoids or other intensive treatments, keeping the rest of the ritual simple may reduce unnecessary irritation.

Glass Ritual Principle: An intensive treatment should replace complexity for the evening—not create more of it.

Safety & Ingredient Information

For external use only. Avoid direct contact with the eyes and discontinue use if persistent irritation occurs.

Because the ampoule contains niacinamide and a vitamin C derivative, practitioners with highly reactive skin should introduce the treatment cautiously.

The rubber mask should be handled gently because the material can tear if pulled excessively or contacted with sharp objects.

Ingredient formulations can change over time. This product has also existed in different versions, so practitioners with known allergies or sensitivities should compare the ingredient list printed on the specific product packaging they receive.

Glass Ritual does not promise that an occasional cosmetic mask will remove pigmentation or dark spots. We position this as supplementary brightening care that may help improve the appearance of dullness, visible discolouration and uneven-looking skin tone.
