How to use
HOW TO USECleanse & Prep Your Skin
Start with clean skin. Apply your toner and/or serum as usual. The mask works best on slightly damp, prepped skin.
Apply the Two-Piece Mask
Remove the mask from packaging. The two-piece design (upper and lower) allows for a customized fit. Smooth out any air bubbles.
Use Extra Pieces
Don't waste the eye and mouth cutouts! Apply them to nose sides, under-eyes, neck, or anywhere needing extra hydration and firming.
Wait for Transparency
Leave on for 3-4 hours minimum, or overnight for best results. The mask turns from opaque white to completely transparent when done.
Remove & Skip Washing
Gently peel off the mask. Do NOT wash your face—pat any remaining essence into skin. Apply SPF if using in the morning.

Frequently asked questions
FAQYes, this mask is generally considered safe for pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or other ingredients typically avoided during pregnancy. The main actives—niacinamide, adenosine, and collagen—are generally considered safe. All ingredients are EWG green-rated. However, as with any skincare product during pregnancy, it's always best to consult with your healthcare provider before use.
This mask is NOT considered fungal acne safe. It contains Galactomyces Ferment Filtrate (a fermented yeast ingredient) and Polyglyceryl-10 Laurate, both of which may feed malassezia yeast. If you're prone to fungal acne, we recommend patch testing first or choosing a fungal acne-safe alternative like products without ferments or esters.
Yes, this mask can be used with most active ingredients. For sensitive skin, consider alternating nights rather than layering directly over strong actives like retinol or high-concentration AHAs. The mask's hydrating and soothing properties can actually help buffer potential irritation from actives when used on alternate nights. Vitamin C serums can be applied before the mask without issues.
This mask is best suited for dry, normal, combination, and mature skin types seeking intense hydration and a glass skin glow. It excels for dehydrated, dull skin and works great as a pre-event treatment. Use with caution if you have very oily or acne-prone skin, as some users report clogged pores and congestion from the rich collagen formula.
Results are immediate! You'll see visible glass skin glow, plumper texture, and minimized pores right after removing the mask. This immediate effect typically lasts 24-48 hours before fading after washing. Clinical studies show hydration effects can last 150+ hours. However, note that the dramatic visual results are temporary—this is best used as a weekly treatment or pre-event skin prep rather than expecting permanent changes.
Apply the mask as the last step of your evening skincare routine, after cleansing, toner, and any serums. You can also use it during the day for 3-4 hours. After removing, do NOT wash your face—simply pat in any remaining essence. Skip moisturizer as your skin will be fully hydrated. In the morning, just apply sunscreen as usual.
The mask has a low comedogenic rating of 1/5, with most ingredients being non-pore-clogging. However, individual experiences vary—some users with oily or acne-prone skin have reported congestion and small bumps after use. The rich, collagen-heavy formula is concentrated for maximum effect, which may be too much for easily-clogged skin. If you're prone to breakouts, start with occasional use and monitor your skin's response.
Each mask should be used immediately after opening the individual packet—it's not designed for reuse or storage after opening. Unopened masks have a shelf life of 24-36 months from manufacture date when stored properly in a cool, dry place. Check the expiration date printed on the packaging. The individually sealed packets ensure each mask stays fresh until you're ready to use it.
Verdict: The BIODANCE Bio-Collagen Real Deep Mask delivers on its promise of instant glass skin glow and deep hydration. The 243 Dalton ultra-low molecular collagen and 150+ hour hydration claims are backed by clinical testing, and the results are immediately visible. It's a luxurious treat for dry, normal, and mature skin types seeking pre-event radiance. However, the temporary nature of results, premium price point, and potential issues for oily/acne-prone skin keep it from being a 5-star product. Best used as a weekly indulgence or before special occasions rather than a daily essential. If you loved the TikTok hype and have suitable skin type, you'll likely love this mask. If you're oily, acne-prone, or expect permanent anti-aging results, manage expectations accordingly.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.

Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.

Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.

Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
What are Notable Effects & Ingredients?
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

Pro Tip Alert!
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

What is the Ingredient Safety Breakdown?
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
Pro Tip Alert!
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
