Ingredient breakdown
INGREDIENTSMuan Red Onion Extract 50,000+ ppmProven
A specialized red onion variety from Muan, South Korea containing 30-40x more phytonutrients than regular onions. Rich in quercetin and kaempferol flavonoids with clinically studied anti-scar and anti-inflammatory properties.
- Quercetin: Inhibits fibroblast proliferation and collagen overproduction, reducing scar formation
- Kaempferol: Provides anti-inflammatory and antibacterial benefits
- Clinical Use: Onion extract has been used in scar treatment for 60+ years (e.g., Mederma)
Tranexamic AcidProven
A synthetic amino acid derivative clinically proven to reduce hyperpigmentation. Works by inhibiting melanin production through the plasminogen/plasmin pathway, making it effective for melasma and post-inflammatory hyperpigmentation (PIH).
- Study: 2019 research showed 27% reduction in melasma severity after 12 weeks of topical use
- Mechanism: Blocks melanocyte-keratinocyte interaction and reduces inflammatory mediators
- Synergy: Works even better when combined with Vitamin C derivatives
Sodium Ascorbyl Phosphate (Vitamin C)Proven
A stable, water-soluble form of Vitamin C that converts to ascorbic acid in the skin. Provides brightening and antioxidant benefits without the instability issues of pure Vitamin C.
- Benefit: Evens skin tone and protects against oxidative stress
- Stability: More stable than L-ascorbic acid in water-based formulas
- Synergy: Enhances the pigment-reducing effects of Tranexamic Acid
NoSCalm ComplexSoothing
Isntree's proprietary calming complex designed to soothe sensitive and irritated skin while supporting barrier function.
- Sodium Heparin: Anti-inflammatory agent that improves microcirculation

Budget-friendly alternatives (dupes)
DUPESSimilar gentle, low-pH formula for sensitive skin. Uses Tea Tree and BHA instead of Onion Extract. Lacks Tranexamic Acid for brightening but excellent for basic gentle cleansing.
Focus on hydration with deep sea mineral water instead of brightening actives. Pearly, creamy texture. Better for dry skin but lacks the scar-healing benefits of onion extract.
Same brand, different focus. 8 types of Hyaluronic Acid for intense hydration. Better for dehydration concerns but lacks the spot-care and brightening benefits.

Frequently asked questions
FAQYes, this cleanser is considered safe during pregnancy and breastfeeding. It does not contain any of the ingredients typically avoided during pregnancy such as retinoids, salicylic acid (BHA), hydroquinone, or chemical sunscreens. The formula relies on gentle, pregnancy-compatible ingredients including Tranexamic Acid and Vitamin C derivative, both of which are considered safe for topical use during pregnancy.
No, this cleanser is NOT fungal acne safe. It contains several fatty acids that can potentially feed Malassezia yeast, including Stearic Acid, Myristic Acid, Palmitic Acid, Oleic Acid, and Arachidic Acid. If you have diagnosed fungal acne or are prone to Malassezia-triggered breakouts, consider alternatives like the Round Lab 1025 Dokdo Cleanser or Etude House SoonJung pH 6.5 Whip Cleanser.
Yes, this cleanser is compatible with most active ingredients. Since it's a rinse-off product, the Tranexamic Acid and Vitamin C won't interact negatively with your leave-on actives. It's gentle enough to use in routines with retinol, Vitamin C serums, or exfoliating acids. However, if you're using strong actives, you may appreciate this cleanser's soothing properties to help balance your routine.
This cleanser is best suited for oily, combination, and acne-prone skin types. It's particularly beneficial for those dealing with post-acne hyperpigmentation, dark spots, or uneven skin tone. The formula is also gentle enough for sensitive skin, though those with very dry skin may find it slightly drying. If you have fungal acne, this product is not recommended.
Cleansing benefits are immediate - you'll feel clean, refreshed skin from the first use. For brightening and dark spot reduction, expect to see gradual improvement over 6-12 weeks of consistent use. Studies on topical Tranexamic Acid show a 27% reduction in hyperpigmentation after 12 weeks. Remember that a cleanser is a rinse-off product, so results are more subtle than leave-on treatments.
Use this as your water-based (second) cleanser in a double-cleanse routine. If wearing makeup or sunscreen, start with an oil cleanser, then follow with this foam cleanser. It can be used both morning and night. After cleansing, continue with toner, essence/serum, moisturizer, and sunscreen (AM only). For enhanced results, pair with other products from the Isntree Onion Newpair line.
This cleanser has a low comedogenic rating of 2 out of 5, meaning it has a low risk of clogging pores. While it contains some fatty acids, the overall formula is designed to cleanse without leaving pore-clogging residue. It's suitable for acne-prone skin. Just ensure you rinse thoroughly to prevent any film from forming on the skin.
The product has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal efficacy and safety. The 150ml tube typically lasts 3-4 months with twice-daily use, as a little product goes a long way. Store in a cool, dry place and keep the cap tightly closed between uses.
Verdict: The Isntree Onion Newpair Cleansing Foam is an excellent choice for those dealing with post-acne marks and uneven skin tone who want a gentle, effective cleanser. The combination of Muan Red Onion Extract, Tranexamic Acid, and Vitamin C offers genuine brightening benefits rarely found in cleansers. It's pregnancy-safe, hypoallergenic, and works well for most skin types. The main drawbacks are that it's not fungal acne-safe and may feel slightly drying for very dry skin. For the price point, you're getting a well-formulated cleanser with clinically-backed active ingredients that goes beyond basic cleansing. Best for oily, combination, and acne-prone skin looking to address hyperpigmentation while maintaining a gentle routine.
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.
