Frequently asked questions
FAQYes! This sleeping mask is completely safe for pregnancy and breastfeeding. It contains no retinoids, salicylic acid (BHA), hydroquinone, chemical sunscreens, or any other ingredients that are contraindicated during pregnancy. The formula focuses on gentle hydration with hyaluronic acid, ceramides, and soothing Centella Asiatica - all pregnancy-safe ingredients.
Yes! This is one of the most popular fungal acne safe sleeping masks on the market. The formula is free from fatty acids, oils, esters, polysorbates, and fermented ingredients that feed malassezia yeast. It has been verified FA-safe by multiple ingredient analysis sites including SkinCarisma, SkinSort, and Simple Skincare Science.
Absolutely! This sleeping mask is an excellent companion to active ingredients. Apply your retinol, vitamin C, or acids first, wait a few minutes for absorption, then apply the sleeping mask as a final hydrating and soothing layer. The hyaluronic acid and Centella help counteract potential dryness or irritation from actives while locking in their benefits.
This sleeping mask works well for all skin types but is especially excellent for: dehydrated skin, combination skin, sensitive skin, acne-prone skin, and those with fungal acne. The lightweight gel texture makes it suitable even for oily skin, though those with very dry skin may want to layer it over a richer moisturizer for maximum hydration.
You'll notice immediate hydration upon application. By the next morning, skin typically feels softer, plumper, and more dewy. For lasting improvements in skin texture and barrier function, use consistently for 2-4 weeks. Many users report their best results after about one month of nightly use.
Apply as the very last step of your evening skincare routine, after cleansing, toning, serums, and moisturizer. The sleeping mask acts as a seal to lock in all previous products and provide overnight hydration. You can use it over or instead of your regular night moisturizer depending on your skin's needs.
No, this sleeping mask is non-comedogenic with a rating of 1/5. The oil-free gel formula is specifically designed not to clog pores. It contains no comedogenic oils or heavy occlusives. It's safe for acne-prone skin and has been dermatologically tested.
The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal efficacy and safety. Store in a cool, dry place away from direct sunlight. The 100ml tube typically lasts 2-4 months with nightly use, depending on how much product you apply per session.
Verdict: The Isntree Hyaluronic Acid Water Sleeping Mask is an exceptional choice for anyone seeking deep overnight hydration without the risk of irritation or breakouts. Its unique combination of 5 types of hyaluronic acid, barrier-strengthening ceramides, and soothing Centella delivers impressive results for such an affordable price point. The fungal acne safe and pregnancy safe formulation makes it stand out from competitors like Laneige. While some may find the initial tacky texture takes getting used to, the morning-after results of plump, dewy, glass-like skin make it absolutely worth it. A must-have for K-beauty enthusiasts and sensitive skin types alike.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
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!
Ingredients Related to Skin Types
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.
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.
