The formula is gentle, fragrance-free, and focuses purely on hydration with hyaluronic acid and soothing botanical extracts.

Yes, this toner is verified fungal acne safe. It contains no fermented ingredients, fatty acids, fatty alcohols, esters, polysorbates, or oils that can feed malassezia yeast. The formula has been analyzed and confirmed safe for those prone to fungal acne/malassezia folliculitis.

Yes, this toner is compatible with all major actives including retinol, vitamin C, AHAs, and BHAs. Apply the toner first on clean, damp skin, let it absorb for about 30 seconds, then follow with your active serums. The hydrating base can actually help buffer potential irritation from stronger actives.

This toner is excellent for ALL skin types, but particularly shines for: dehydrated skin (any type), oily skin wanting lightweight hydration, sensitive/reactive skin, acne-prone skin, and those with fungal acne. The lightweight, fast-absorbing formula works well in any climate, though those in very dry environments may want to layer it more or follow with an occlusive moisturizer.

You'll notice immediate hydration and plumping effect from the first use. Within 1-2 weeks of consistent use, expect improved skin texture and reduced dry patches. After 4-6 weeks, you should notice strengthened skin barrier and better moisture retention throughout the day. Maximum benefits including visible plumping of fine lines typically appear after 8+ weeks of regular use.

Apply this toner as Step 2 immediately after cleansing, while skin is still slightly damp. The order is: Cleanser → This Toner → Essence → Serum → Moisturizer → Sunscreen (AM). You can also use the Korean 7-skin method by layering 3-7 applications of this toner for intense hydration before moving to the next step.

No, this toner has a comedogenic rating of 0/5, meaning it will not clog pores. The formula is completely oil-free and contains no comedogenic ingredients. It's safe for acne-prone skin and won't trigger breakouts. Multiple skincare databases have verified its non-comedogenic status.

The Period After Opening (PAO) is typically 6-12 months, as indicated on the packaging. Given the large 300ml size, it's recommended to use it daily (morning and night) to finish within the PAO period. Store in a cool, dry place away from direct sunlight to maximize shelf life. If the product changes color, smell, or texture, discontinue use.

A worthy staple for any skincare routine.

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.

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.
