This toner is excellent for all skin types but particularly shines for sensitive, irritated, acne-prone, and oily/combination skin.

You'll feel immediate soothing and hydrating effects right after application. Visible reduction in redness typically occurs within 1-2 weeks of consistent use. For significant improvements in skin barrier function and sebum balance, allow 6-8 weeks of daily use. Clinical studies showed best results after 8 weeks of continuous use.
Apply immediately after cleansing as the first step of your routine (or second, if using a first-treatment essence). Follow with essence, serum, moisturizer, and sunscreen (AM).

It excels at calming sensitive, irritated, and redness-prone skin without any unnecessary additives. While it may feel "too simple" for those seeking multi-tasking formulas, its purity is precisely its strength. Perfect for those who believe less is more, fungal acne sufferers, pregnant/nursing mothers, and anyone seeking to simplify their routine with a genuinely gentle, K-beauty essential. Best paired with the Mixsoon Heartleaf Essence for enhanced calming benefits.

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

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.
