What kind of adapter does the UNclog mask use?

The mask works with a 5V/2A adapter. We've found that not all adapters work the same. If you don't have another adapter, try plugging it into your laptop or PC.

Why does the mask does not seem to heat adequately?

NOTE: You will feel more of the warm and relaxing effect once the mask is on the eyelids.

The theraputic effect occurs when the warmth from the mask binds with the Far infrared generated by our body heat. 

Couple of other factors that might have caused the mask to lag:

Not connected to the correct adapter. The mask only works with at least a 5V/2A output adapter. Anything less won't work as efficiently. And often, not every adapter works the same. We recommend using our adapter.

On a new mask, the fibers need to be broken into first. 

Pre-heating before initial use is recommended.  

Here are the instructions to preheat the mask:

1. Fold the mask in half, so the inner part is touching each other

2. Plug in the UNclog mask.

3. Set the mask to #5(hottest) for 60 minutes.

4. Let it shut off automatically. 

Your UNclog mask is ready to help your eyes relax.

I am not convinced that this mask is warm enough for me.

Our UNclog Heating Eye Mask is developed based on scientifically-backed studies, which suggest the optimum temperatures to heat the clogged glands safely are between 40°C and 50°C (should feel warm, not hot).  It is best to avoid any temperatures above 54°C to prevent thermal burns to the skin.

What is the cover made from?

The cover material is made from velvety Polyester — it is soft and comfortable even on sensitive skin.

What technology is used to emanate the IR radiation?

The heating unit uses fibers impregnated with FIR-emitting ceramic nano particles woven into the fabric.

Measurement of the FIR wavelength of the IR radiation emitted by UNclog Heat Mask is between 650-800 range.

Wavelengths of 3 μm to 1,000 μm within the infrared range of electromagnetic radiation (light) are known more specifically as far-infrared.

There are many electric-powered heating masks available in the market. What makes your product more novel in treating MGD?

The purpose of using a heated eye mask is to warm up the clogged Meibomian glands. 

How are we different?

 1. We have over 30 yrs working in the eye care field and designed our UNclog mask based on the basic science of how to melt the meibum effectively and safely.

2. Passionate about what we do. Our eyes are the gate to our safety and good feelings. Having a clear vision is beyond what the eyes can see.

3. Solid one-year warranty and a 30-day money-back guarantee plus great customer service

4. We do not source from e-stores like Alibaba. Our UNclog mask is designed here in the USA. 


Unclog mask is effective and within the safe range.

It is weighted with pink quartz. There is just enough weight on the beads and you can move the beads around to snuggle into the tricky inner corners of the eyelids.

The washable cover promotes hygiene

The Far-Infrared (FIR) heating technology has been proven to be superior in comparison to regular heating.

The highest temp. level mentioned is 50°C, but does the mask really reach that temperature in 5 to 10 minutes?

Yes. Unlike the microwavable masks, the UNclog Heating Eye Mask provides a controlled steady temperature with an automatic shut-off feature.

Timing - is there a control one can set so it will turn off after a specific time? Or does it automatically shut off after a specific time?

The timer button is set to automatic shut-off at 20 min, 30 min, 40 min, 50 min, and 60 min.

 Does it contain any glues?  

There is no glue on the eye mask part; however, there might be some glues on specific controller models.

 Does it have any odor?

The mask might generate some odor from the fibers during the initial preheating and might have some traces of Lavender scent.

What country is it made in?

UNclog mask is designed and developed in the USA

Madnufactured in Taiwan

What type of fabric is used


The cover of our mask is washable. We recommend washing the cover before using it. Even though we are unaware of any additive on the fabrics, some trace of elements might have been picked up from other sources or elements.

 How long is its warranty? 

We offer a One-year warranty from the date of purchase.

  Has it been in any studies (ie that confirm best temperatures , etc?

There are many studies done. Here is one of them:

The optimum temperature for the heat therapy for  Meibomian gland dysfunction https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6529265/


Heating the eye lid above the phase transition temperature of meibum increases the disorder of meibum lipid which could ameliorate dry eye symptoms. The optimum temperature for disordering Mn and MMGD to 90% maximum disorder is 40 and 41.5 °C, respectively. Safety issues and discomfort should be considered in obtaining an optimal level of disorder, especially for severe cases of dry eye.

A glance at Far-Infrared (FIR) warmth

Far Infrared Rays are invisible wavelengths of light. Invisible because they are longer than the regular light we see.

This invisible wavelength of light absorbed by the body can be felt as heat. Our bodies also radiate Far-Infrared warmth.

When the body absorbs Far Infrared Rays it is like being in the sunshine the body is warmed up, you feel nice and relaxed full of energy. 

1. Far-infrared are more efficient, penetrate quicker, and provide faster response in the body.

Far-Infrared is absorbed by the molecules in six vibrational modes (scissoring, rocking, wagging, twisting, symmetric and asymmetric stretching).

The National Library of Medicine PMC369987

2. Increases surface blood flow without increasing blood pressure, by promoting dilation of the blood vessels.

3. Improved flexibility. Warming up the muscle and connective tissue can help it become more pliable, restoring its elasticity

* 4. Studies showed FIR benefits the Nitric oxide, one of the most important molecules for blood vessel health  Nitric Oxide Synthase - an overview

Far-infrared radiation acutely increases nitric oxide production by increasing Ca(2+) mobilization and Ca(2+)/calmodulin-dependent protein kinase II-mediated phosphorylation of endothelial nitric oxide synthase at serine 1179

Using FIR as a thermal therapy agent, we investigate the molecular mechanism of its effect on endothelial nitric oxide synthase (eNOS) activity and NO production. FIR increased the phosphorylation of eNOS at serine 1179 (eNOS-Ser(1179)) in a time-dependent manner (up to 40min of FIR radiation) in bovine aortic endothelial cells (BAEC) without alterations in eNOS expression. This increase was accompanied by increases in NO production and intracellular Ca(2+) levels. Treatment with KN-93, a selective inhibitor of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) and H-89, a protein kinase A inhibitor, inhibited FIR radiation-stimulated eNOS-Ser(1179) phosphorylation. FIR radiation itself also increased the temperature of culture medium. As transient receptors potential vanilloid (TRPV) ion channels are known to be temperature-sensitive calcium channels, we explore whether TRPV channels mediate these observed effects. Reverse transcription-PCR assay revealed two TRPV isoforms in BAEC, TRPV2 and TRPV4. Although ruthenium red, a pan-TRPV inhibitor, completely reversed the observed effect of FIR radiation, a partial attenuation (∼20%) was found in cells treated with Tranilast, TRPV2 inhibitor. However, ectopic expression of siRNA of TRPV2 showed no significant alteration in FIR radiation-stimulated eNOS-Ser(1179) phosphorylation. This study suggests that FIR radiation increases NO production via increasing CaMKII-mediated eNOS-Ser(1179


We found that one of the easiest ways to recycle any old electronics, including cables and chargers, is through Best Buy. Every Best Buy location in the US has a kiosk for recycling just inside the door. However we recommend that you check with each store to make sure.

You can also repurpose it.

- The cover can be reused as a sregular sleep mask.

- The Velcro can be used for arts and crafts project. Great for hair accessories since the velcro does not stick to hair.

- Rose quarz insert can be used as cold compress.

Lets help us repurpose and recycle.

How to wash UNclog Mask?

UNclog Mask can be either hand wah or put in a regular cycle in the washing machine

Is it safe after cataract surgery?

Is it safe after cataract surgery? Yes, UNclog mask is safe post-cataract surgery if your surgeon recommends it. 

UNclog mask is safer than the microwavable one because the temperature is controlled (too hot temperature can potentially damage the delicate corneal tissue, especially after surgery)

UNclog mask is hygienic; the cover is removable and washable, plus it is weighted with rose quartz (unlike flaxseeds, it will not go rancid).


How does the cold setting work?

Excess heat can manifest as inflammation, swelling, redness, irritation, or overactivity.
Rose Quartz is a cooling gemstone. It naturally transfers heat out of the body. For example, touching the quartz countertop feels cool and will warm up from body heat.
Rose Quartz is heavier and harder than glass. The tumble Rose Quarz inside the insert weight can spread evenly to fill the inner corners or be isolated.
For Instant Cooling: Place the crystal insert (Pink) on the area that needs cooling.
For Longer Cooling: the UNclog crystal insert can be placed either in the refrigerator or the freezer for a few minutes.
