Face masks are the step that almost everyone considers optional, and in most cases, they really are. When we decided to add one to the Acnerebal line, we asked ourselves a specific question: what can a mask do that a cream applied every day doesn't already do better?
In summary
- SkinPure Rebalance is a purifying clay mask for combination, oily, and blemish-prone skin, in a 10 ml single-dose sachet.
- Alongside the clay complex (Kaolin and Fuller's Earth), Potassium Azeloyl Diglycinate and Zinc PCA, two sebum-regulating active ingredients, do their work.
- The texture is not dry clay but a clay cream: it contains organic linden water, panthenol, allantoin, hyaluronic acid, and shea butter.
- This is the difference from traditional clay masks: it does not crack or leave the skin stripped, so it can be left on for 15-20 minutes without dehydrating the skin.

The problem with classic clay masks
LClay works by absorption: it traps sebum, impurities, and surface residue and removes them when rinsed off. It is a physical mechanism, effective and known for centuries, and it gives immediate satisfaction on oily skin.
The limitation appears afterward. A mask that only absorbs leaves the skin temporarily mattified but also more depleted of its protective film, and oily skin often responds to this depletion by producing even more sebum. It is the same rebound effect we see with overly harsh cleansers, and the reason many people say that clay masks "work for one day."
There is also the physical problem with pure clay: when it dries completely and starts to crack, it has finished absorbing sebum and begins drawing water from the skin. From that moment on, it is no longer working: it is dehydrating. This is why the setting time for many traditional masks needs to be monitored carefully.
When we worked on this formula, the goal was not to improve absorption. It was to remove the trade-off: maintain the purifying action without the price usually paid.
How the formula is made
The clay complex: Kaolin and Fuller's Earth
Not just one clay, but two. Kaolin has a gentler absorbent action, while Solum Fullonum—fuller’s earth—is more absorbent of sebum. Together, they absorb excess sebum and surface impurities, reduce shine, and improve the appearance of skin texture. For more on how clays work on the skin, see our guide to facial clay.
Potassium Azeloyl Diglycinate
It’s a derivative of azelaic acid that’s much more soluble and much better tolerated than the original molecule. It helps balance sebum production, improve the appearance of blemishes, and promote a more even complexion. It’s one of the active ingredients we return to most often in our formulas. Find out more here: azeloglycine.
Zinc PCA
Zinc in the form of a salt of pyrrolidone carboxylic acid. It helps control excess shine and maintain skin balance without compromising the skin’s natural hydration: that’s exactly what sets it apart from a pure sebum absorber. Find the details in the Zincidone and oily skin guide.
The soothing and hydrating complex
This is what explains the cream-clay texture, and what’s usually missing from purifying masks: organic linden water, panthenol, allantoin, and hyaluronic acid, together with shea butter and sweet almond oil.
They help keep the skin soft and comfortable during the treatment, not just afterward. That’s why you can leave it on for up to 15-20 minutes: the mask never reaches the point where the clay starts to dry and work against you.
Sage and mint
They complete the formula’s balancing and sensory profile, while mint provides a refreshing sensation that makes the experience pleasant. One honest clarification: the perceived freshness is not a therapeutic effect; it’s a sensory one. It matters because a product you enjoy using is one you’ll use, not because the sensation corresponds to an active effect.

Why single-dose sachets
It's a choice that deserves an explanation, because it may seem like a simple matter of format, but it's not.
- No contamination. You dip your fingers into a jar of mask for months. With a sachet, you open it, use it, and that's it.
- The right dose, guaranteed. The contents are measured for one full-face application: you won't use too much or too little.
- Fresh active ingredients. Botanical extracts and essential oils degrade when exposed to air: a single-dose sachet delivers them to your face as formulated.
Use the sachet immediately after opening. That's the only limitation of this format, and in return it eliminates the three problems mentioned above.
How to use
- Apply to a cleansed, dry face, spreading the entire contents of the sachet.
- Avoid the eye area and lips.
- Leave on for 15-20 minutes.
- Rinse thoroughly with lukewarm water, never hot, without rubbing.
- Continue with the routine treatment.
The recommended frequency is once or twice a week. If you have combination skin, you can apply it all over your face or mainly to the T-zone: it's the simplest way to address two different needs with one product.
How to complete the treatment
The mask is part of the Acnerebal line, so after rinsing it off, the natural next step is to use products from the same line, allowing the active ingredients to complement one another rather than overlap:

ACNEREBAL CREAM Cream for hormonal acne and oily skin, mattifying effect Sebum-regulating cream with Azeloglycine, Zincidone® and Nia... Discover ACNEREBAL CREAM
What not to do on the same evening
One piece of advice we always give, and that matters more than many instructions for use: don't use the mask on the same evening as an exfoliant. Both steps act on the skin's surface, and combining them doesn't double the results: it doubles the risk of irritation.
The same applies to retinoids. On the evening you use the mask, simply moisturize after rinsing it off. For how to spread your skincare steps throughout the week, follow the approach described in the oily skin routine.
Who it's for and who it's not for
It makes sense for combination, oily, and blemish-prone skin, with excess sebum, shine, enlarged pores, and uneven texture, as well as for asphyxiated skin. The formula is dermatologically tested for sensitive skin and nickel tested.
It makes less sense for dry or thin skin: there, the goal isn't to absorb but to rebuild, and a purifying mask works in the opposite direction. And it isn't the right product for skin with couperose or vascular redness: the formula contains aromatic extracts and essential oils that provide its characteristic freshness, and it's best to avoid any such stimulation on skin with reactive capillaries. In that situation, a different approach is needed.
In cases of inflammatory acne with nodules or scarring, a dermatologist remains the point of reference: a cosmetic can complement a treatment plan, but not replace it.
Where to find it
Like the rest of the range, it is available in pharmacies and para-pharmacies. We maintain this approach because, for blemish-prone skin, the right question isn't which mask to buy, but whether the problem is truly excess sebum or a compromised barrier that's protecting itself — and you can tell the difference by looking at a person, not by reading a description.
