The Green Mask Stick is a viral TikTok trend of a product that apparently reduces facial blemishes like acne, blackheads and dark spots on the skin. The brand sponsored TikTok videos with miraculous results, showing their product significantly improving the aesthetics of people’s faces after only 10 minutes of use.
In this article we’ll review the ingredients in Green Mask Stick based on published medical research to determine if it’s likely to be effective, or if it’s just a clever marketing trick.
There are many “green mask stick” products online, as you’re probably aware if you’ve tried to purchase the same products used in the viral TikTok videos. There doesn’t appear to be one clear manufacturer of this product, and no branded website shows up at the top of the search results on Google.
We noticed that a green mask stick brand called Meidián was the one used in most of the viral videos. The most viral TikTok video on green mask stick, which achieved nearly 10 million views, used this brand. The most viral YouTube video on green mask stick achieved 9.5 million views and used the same brand.
We found the Meidián product on Amazon, and this is the green mask stick formulation we will be reviewing in this article.
Meidián green mask stick has four active ingredients: glycerin, kaolin, green tea extract and Vitamin E.
Glycerin is often used in cosmetic formulations for skin hydration, but there isn’t much medical research backing this effect. One clinical trial found that a cream containing 20% glycerin improved skin hydration in human volunteers, but the green mask stick company doesn’t publish the glycerin concentration of their product.
Another medical study published in the Advances in Dermatology and Venereology journal found that topically-applied glycerin was helpful in treating chronic dry skin. We’ll conclude that this ingredient is likely effective for skin hydration but not for treating skin blemishes.
Kaolin is a type of clay that’s often used in cosmetic masks. There isn’t much research backing the efficacy of clay used on skin. A medical review from 2021 examined the health effects of commercial clays, and concluded that “while many commercially-available bioceutical clays possess mineral constituents found in successful antibacterial clays, they do not possess any antibacterial effects.” This suggests that this ingredient would be ineffective for treating acne, which is often bacterial in nature.
We can’t locate any medical research suggesting that kaolin clay can improve skin quality in humans, nor does the green mask stick company share any, so we will conclude that this is an ineffective ingredient.
Green tea extract is the third active ingredient, and this actually is an effective ingredient choice. As we discussed in our review of the popular Hanacure mask, a 2019 publication in the well-respected Molecules journal detailed how green tea extract can significantly delay signs of skin aging due to inhibition of specific skin enzymes.
The final ingredient in Meidián’s green mask stick is Vitamin E, which is surprisingly another effective choice. Vitamin E is proven in medical research to have a photoprotective effect, meaning it can reduce the damaging effects of solar rays on the skin, which are one of the leading causes of skin aging.
Another medical review found that Vitamin E was a potential therapeutic for inflammatory skin diseases such as atopic dermatitis and psoriasis. It can minimize inflammatory immune responses in the skin, according to the study authors.
Overall we find that this product has a relatively effective formulation for improving skin quality, but certainly don’t find it likely to cause dramatic changes in skin quality after 10 minutes. That’s nearly impossible for any skincare product, and we suspect that the promotional TikTok videos showing complete reduction of acne and/or blackheads involved editing effects.
Failure to Publish Entire Ingredients List
Like many low-quality brands, the manufacturer of Meidián green mask stick doesn’t publish the full list of ingredients on their Amazon listing; only the 4 active ingredients we discussed in the previous section.
This product almost certainly contains inactive ingredients such as coloring agents, because none of the 4 active ingredients are green in color, and the product is green in color.
We believe it’s unacceptable for cosmetics companies to fail to publish the full list of ingredients, because consumers deserve to have access to all of the information about a personal care product. A consumer might have an allergy to an inactive ingredient, and without the manufacturer publishing the ingredients list this consumer will be harmed.
We recommend avoiding brands that don’t publish a full list of ingredients.
If your concern is acne and blemishes on the skin, there are natural alternatives with much more research backing than the green mask stick.
Red light therapy is a surprisingly effective non-toxic acne treatment. A clinical trial published in the Dermatologic Surgery journal evaluated the effect of red light therapy for treating acne, and found that it reduced acne lesions by nearly 70%.
Red light therapy involves the therapeutic use of red wavelengths of light, typically fixed to a large panel, and is effective because the light penetrates skin and can have an anti-inflammatory effect.
We recommend that patients speak with their doctor before purchasing a commercial red light therapy panel, because this is a novel type of treatment, and there are still long-term safety questions.
Tea tree oil has also been found to be an effective topical treatment for acne. A medical trial found that tea tree oil can treat mild to moderate acne at a concentration of 5%. It’s extremely important to not use an undiluted tea tree oil directly on the face. It needs to be properly diluted to be safe. The linked study used a concentration of 5%, which means 1 part tea tree oil to 20 parts carrier oil.
In the above-linked study, tea tree oil at a concentration of 5% decreased Acne Severity Score (ASI) in patients 5.75x more than placebo.
A second medical study further confirmed the efficacy of tea tree oil for acne, finding that it significantly reduced acne lesions compared to placebo.
The reviews of the Meidián brand Green Mask Stick on Amazon are unimpressive. It has a rating of 2.5 stars out of 5, which is low for a popular Amazon product.
Many users found the product totally unhelpful, which isn’t surprising based on our review of the ingredients. One of the most popular reviews stated: “Total scam. Mask does absolutely nothing. Completely false product. DO NOT BUY...SCAM”.
Another user said “Videos lie...does not remove blackheads” – since none of the ingredients are proven effective for treating acne, we’re unsurprised that users are unhappy that there’s no quick resolution of their acne.
Green Mask Stick Frequently Asked Questions
Does the Green Mask Stick Work?
While some of the ingredients in isolation may be effective for improving skin quality, there is no evidence that this product works as the company hasn’t funded any studies proving it does. The brand doesn’t even publish the entire ingredients list, so there’s no way to tell for certain whether it will work.
How to Use Green Mask Stick?
According to the instructions posted by the brand on Amazon, you first apply the cream to the face and then allow it to sit for 10 minutes. After 10 minutes and once the paste is fully dried, wash it off with water and gently dry the face.
Is Green Mask Stick Available At Walmart?
There is a Meidián green mask stick product available for sale on Walmart’s website, but it has a different listed manufacturer from the product we reviewed in this article. It also has no published ingredients and no reviews, so we don’t believe this product is legitimate and would recommend avoiding it.
There are other green mask stick products available on Walmart with different formulations from the one we reviewed, but we would recommend avoiding those as well because the Meidián brand seems to be the most popular version of this product.
Does the Green Mask Stick Contain Chia Seeds?
Some of the promotional TikTok videos on the Green Mask Stick included chia seeds, but this ingredient isn’t in the formulation of the product. We find this to be deceptive marketing.
