Ingredient breakdown

INGREDIENTS

5 Types of Hyaluronic AcidProven

A powerful blend of multi-molecular weight hyaluronic acids that work at different skin depths. Smaller molecules penetrate deeper for intense hydration, while larger molecules form a protective moisture barrier on the surface.

  • Sodium Hyaluronate: Standard HA salt for surface hydration and moisture retention
  • Hydrolyzed Hyaluronic Acid: Low molecular weight for deeper penetration
  • Hydroxypropyltrimonium Hyaluronate: Cationic HA that adheres better to skin
  • Sodium Acetylated Hyaluronate: Acetylated form with 2x better skin adhesion
  • Ascorbyl Propyl Hyaluronate: Vitamin C derivative + HA for brightening hydration
HA can hold up to 1,000 times its weight in water, making it one of the most effective hydrating ingredients available.

Ceramide NPProven

An essential lipid naturally found in the skin barrier. Ceramide NP helps restore and maintain the protective layer that keeps moisture in and irritants out.

  • Barrier Repair: Fills gaps between skin cells to strengthen moisture barrier
  • Moisture Lock: Prevents transepidermal water loss (TEWL)
  • Research: Studies show ceramides improve skin hydration by up to 30%

Centella Asiatica ExtractProven

Also known as Cica or Gotu Kola, this traditional Asian herb is prized for its remarkable healing and soothing properties.

  • Active Compounds: Contains asiaticoside, madecassoside, asiatic acid, and madecassic acid
  • Benefits: Anti-inflammatory, wound healing, collagen synthesis support
  • Clinical Use: Widely studied for treating burns, wounds, and irritated skin

Beta-Glucan HighProven

A powerful polysaccharide derived from oats, yeast, or mushrooms with exceptional soothing and hydrating properties.

  • Hydration: Comparable to hyaluronic acid in water-holding capacity
  • Soothing: Reduces redness and calms irritated skin
  • Antioxidant: Protects skin from environmental damage

Betaine (Natural Moisturizing Factor)Proven

A natural amino acid derivative that mimics the skin's own moisturizing factors. Works as a powerful humectant to draw and retain moisture.

  • Function: Osmolyte that helps cells retain water under stress
  • Source: Derived from sugar beets
  • Benefit: Prevents moisture evaporation while soothing irritation

Panthenol (Pro-Vitamin B5)Proven

A humectant and emollient that penetrates deep into skin layers to provide long-lasting hydration and support skin healing.

  • Penetration: Converts to pantothenic acid (B5) in skin for deeper absorption
  • Benefits: Wound healing, anti-inflammatory, barrier repair
  • Compatibility: Safe for all skin types including very sensitive

FAQ

Yes! 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.

— Skincarisma verdict
4.5 / 5 ★★★★★

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.

question
lightbulb 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.

muscle 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

question
lightbulb 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.

muscle 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.
