Yes, this gentle extract pairs well with most active ingredients. Its soothing and anti-inflammatory properties can actually help buffer potential irritation from actives like retinol or exfoliating acids. Apply the extract first to prep and calm skin, then follow with your actives. For vitamin C, you can use them in the same routine without issue.
This extract works excellently for oily, combination, sensitive, and acne-prone skin types. Its lightweight, watery texture absorbs quickly without adding shine or heaviness. While suitable for dry skin too, those with very dry skin may want to layer it multiple times or follow with a richer moisturizer. It's particularly beneficial for anyone experiencing redness, irritation, or breakouts.
You'll feel immediate soothing and cooling effects upon application. Visible reduction in redness typically appears within 1-2 weeks of consistent use. For acne control and clearer skin, most users report improvements around 4-6 weeks. Long-term benefits like fading acne marks and improved skin resilience develop over 8+ weeks of regular use.
Use this extract as the first treatment step immediately after cleansing. Its thin, watery consistency follows the "thinnest to thickest" rule. You can also use it in place of toner, or mix it with your other products (serums, essences, moisturizers) to boost their calming properties. It can be used both morning and evening.
No, this product has a comedogenic rating of 0/5, meaning it is completely non-comedogenic and will not clog pores. The ultra-lightweight, water-based formula absorbs instantly without leaving any residue. It's specifically formulated to be safe for acne-prone and congestion-prone skin.
The recommended Period After Opening (PAO) is 6 months. Due to its minimal preservative system, the product is best used within this timeframe for optimal efficacy and safety. Store in a cool, dry place, and consider refrigerating after opening to help maintain freshness. The 150ml size typically lasts 2-3 months with daily use, while the 300ml lasts 4-6 months.
Verdict: ONE THING Houttuynia Cordata Extract is an exceptional value for a high-concentration, minimalist Korean skincare product. With 95% Heartleaf extract in just 3 ingredients, it delivers powerful anti-inflammatory and antibacterial benefits without unnecessary additives. Perfect for those seeking a gentle, effective solution for acne-prone, sensitive, or irritated skin. While the simple formula may not provide dramatic instant results and the herbal scent isn't for everyone, its fungal-acne safe, pregnancy-safe, and vegan credentials make it a standout choice. An excellent entry point into K-beauty essence waters and a versatile product that can be used multiple ways.

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.
