Oxygen Water

Merme’s Oxygen Water marks the beginning of a new era in caring for impure skin. Thanks to its innovative oxygen microbubble technology, it provides deep cleansing of blemishes and clogged pores.

How does the revolutionary Oxygen Water work?

• Impure skin occurs because bacteria prefer to grow in low-oxygen environments. They trigger small inflammations – the root cause of pimples and blemishes.
• Tiny oxygen microbubbles penetrate deep into the pores and create an oxygen-rich environment.
• This prevents bacteria from multiplying, and the inflammation/clogging subsides. 
• In the oxygen-rich environment, new bacteria find it difficult to settle again.

When do the first results appear?

• First results can be visible as early as week 1. An initial worsening is possible as deeper impurities come to the surface.
• From day 7, most participants showed initial improvements in their skin condition.
• From day 14, the skin's appearance visibly improved; after 30 days, blemishes were noticeably reduced.

Minimal ingredients, maximum results: The targeted treatment consists of only 4 ingredients. 1. Ultra-pure water, filtered multiple times but still containing minerals unlike distilled water, 2. Highly pure oxygen in tiny bubbles that can penetrate deep into the pores, 3. Common salt in minimal concentration for stabilization, and 4. Hypochlorous acid (HOCl), a mild acid naturally found in the body that ensures microbial stability.

Available in the following sizes:

• Single 50 ml: 7-day treatment
• Spray head: Must be ordered with single units
• 4-week set 200 ml: 4-week treatment, spray head included

Try it: The innovative Merme Pore Clearing Solution uses a cutting-edge microbubble technology where ultra-fine oxygen microbubbles penetrate deep into the pores, supply the skin cells with pure oxygen, and deliver their clarifying effect – a highly effective treatment for visibly clearer skin.

FAQ

What are oxygen microbubbles?

These are ultra-fine oxygen bubbles (1,000 times smaller than a hair – ~0.2μm) – so small that they cannot be seen with the naked eye or even with a light microscope. They penetrate deep into the pores, supply the skin cells with pure oxygen, and unfold their clarifying effect, effectively fighting bacteria and deeply cleansing. At the same time, they boost the cells' metabolism and reduce irritation.

Can Oxygen Water be combined with other products?

Can I use Oxygen Water every day?

We recommend applying the product twice daily (morning and evening) on cleansed skin. This will give you the best skin results.

Can side effects or skin irritations occur?

Since our Oxygen Water consists only of oxygen and highly filtered water, it is especially gentle and there is no potential for irritation or other side effects from the product itself. However, there may be specific skin predispositions that could cause a skin reaction to the product (see below).

What do the 7 days on the bottle mean?

The bottle marks 7 daily doses for your daily use. Divide the daily dose into morning and evening. Spray 25 sprays evenly on your face in the morning and evening using the included spray head, then gently massage it into your face in light circular motions so the pores loosen and oxygen can better penetrate the pores.

Do I need to wash off the product?

No, you let the product fully absorb until your skin is dry.

Can all skin types use Oxygen Water?

Yes, our Oxygen Water is suitable for all skin types, especially for impure and sensitive skin.

Can I use the product if I only have temporary blemishes/pimples?

Yes, definitely! The application is designed as a 7-day treatment and should be used twice daily, in the morning and evening.

Is there a scientific study for the product?

Yes, there are scientific studies on Oxygen Water by Merme that have been conducted by independent institutions.

How long does it take to see results on my skin?

Our clinical studies prove that after just 14 days, clearer skin and fewer impurities are visible.

How long should I use the Oxygen Water?

The application is designed as a 7-day treatment and should be used daily morning and evening. You will get good results if you use the product continuously for 2 weeks, but success also depends on the severity and type of skin impurities, which is why we offer our product in a 4-pack for use over 4 weeks.

How long is the Oxygen Water shelf life?

Unopened, the product is stable for at least 3 months. After opening, we recommend using up the Oxygen Water within one week to ensure the maximum effect of the active oxygen microbubbles.

The oxygen microbubbles contained are very fine and sensitive to air and light. For optimal effect, the product should be used up within 7 days after opening.

Can I use the product during pregnancy?

Yes, it contains only four very mild, dermatologically safe ingredients and is also safe to use during pregnancy and breastfeeding.

What are the advantages compared to products with fruit acids or salicylic acid?

Unlike products with AHA, BHA, or other acids, Oxygen Water by Merme cleanses pores gently and without exfoliation. The innovative oxygen microbubble technology works deep in the pores without stressing the skin barrier – ideal for sensitive skin types that often cannot tolerate traditional acid treatments.

What is the HOCl content in the formula?

We use a very small amount of HOCl solely as a stabilizer – not as an active ingredient. It is about one hundred times less than in pure HOCl products for skin treatment. It supports formula integrity, not direct skin health. Therefore, we do not specify an exact percentage.

Light protection: HOCl is sensitive to UV and visible light and can break down as a result. That’s why we always store the bottles in a box before use. At home, simply keep it in a cabinet or drawer, protected from direct sunlight – and yes, it remains effective for up to 7 days after opening.

How much oxygen is contained in the formula?

We focus on the bubbles – not the oxygen itself – because they are the actual oxygen carriers. Our formula is full of them. It’s not about a fixed oxygen content but about how effectively it is generated, stabilized, and delivered. That makes the difference. On average, there are more than 40,000,000 microbubbles per ml.

The oxygen content changes very little over time as long as the bottle remains closed. The only thing that happens over a longer period is the size of the microbubbles, as bubbles merge over time. This effect is minimal but measurable, which is why we play it safe and use a fixed expiration date.

Does it still work after opening for a week?

After seven days, the effectiveness begins to decrease. The bubbles become slightly larger, which can reduce penetration. For optimal results, we therefore recommend using the product fresh.

Why does my skin look worse after the first week?

Skin cleansing (detox reaction) - Oxygen cleanses the pores. With clogged pores or skin congestion, the microbubbles and HOCl can bring underlying impurities to the surface. This may show as increased breakouts, small blackheads, or blemishes in the first 3–5 days. It is often mistaken for a negative reaction but is usually temporary.

The barrier is already compromised - With excessive peeling, sunburn, or due to retinol, acids, or a damaged barrier of sensitized skin, even a gentle spray mist can sting or cause inflammation. HOCl is gentle but slightly acidic – and the bubbles can enhance the penetration of active ingredients.

Application

• For best skin results, apply the product twice daily on cleansed skin – once in the morning and once in the evening.
• The bottle marks 7 daily doses for everyday use. If you use a spray head, apply 20-25 pumps each morning and evening.
• Gently massaging the applied water into the skin can further enhance its effect.
• Wait until the Oxygen Water has dried – this allows the crucial step where the bubbles can enter the pores and be absorbed by the skin (at least 1-2 minutes).
• Allow skin to dry completely before applying other products. Especially if you use products with antioxidants like retinol, vitamin C, or astaxanthin.
• Use within one week after opening for maximum effectiveness. The product is not dangerous afterward, but the oxygen bubbles grow larger and lose effectiveness.
• Please note: The product is FRESHLY MADE: shelf life 3 months from manufacture (unopened), 1 week after opening.

Active Ingredients

• Aqua (Highly Filtered) - Water purified through especially fine filtration processes. Even microscopic particles like bacteria, pollutants, mineral residues, or organic impurities are removed. Unlike distilled water, not all minerals are filtered out here, making it especially gentle on the skin – ideal for sensitive, irritated skin and providing a high-quality base to improve the effectiveness and stability of skincare formulations.
• Oxygen - The innovative oxygen microbubbles penetrate deep into the pores, release pure oxygen, and inhibit bacterial growth. This combats oxygen deficiency, which is responsible for the proliferation of inflammation-causing anaerobic bacteria – one of the main causes of hormonal or stress-related skin blemishes.
• Sodium Chloride - Known as table salt or sodium chloride, it is a simple but multifunctional ingredient in skincare. In this case, it supports the stability of the oxygen microbubbles. Salt ions help keep the microbubbles, which are mainly stabilized by a slight electrical charge, in solution.
• Hypochlorous Acid - Known for its antibacterial effect while being gentle on the skin, it helps stabilize and preserve the formulation. It is a substance used by white blood cells themselves to fight bacteria.
