FAQs
Everything you need to know before starting your routine with this toner from Korean Essence.
Use it as step 3 in your routine, straight after cleansing and while skin is still slightly damp. Twist off the cap and pour a generous amount into your palm or onto a cotton pad. Press it into the skin with your palms, or sweep gently across the face with the pad. Let it sink in for a few seconds before moving on to serum and cream. Morning and night.
Skin feels calmer immediately on first use. The manufacturer's own measurements show 97.52% better moisture retention after a single use. Redness after cleansing usually reduces noticeably within a week, with a more even skin tone and less sebum after two to four weeks of daily use.
Yes, that's exactly what it's built for. The formula is fragrance-free, free from essential oils and alcohol, and contains neither acids nor retinoids. If your skin is very reactive we still recommend testing on the inner arm for a day before using it on your face.
That the extract makes up 77% of the formula and sits first on the ingredient list, ahead of water. Ingredients are listed in descending order by quantity, so when a plant extract sits ahead of water it isn't a drop added for marketing. It's the base the rest of the formula is built on.
Most toners have water as their base and a small amount of plant extract at the bottom of the list. Here the relationship is reversed. The usual irritants are also completely absent: no fragrance, no alcohol, no essential oils and no exfoliating acids. That makes it usable twice a day, every day, even when skin is in poor shape.
Yes, it works with virtually everything. Use it as the first step after cleansing, before serum, ampoule and cream. It pairs well with acids, retinol and vitamin C, and used before them it often calms the irritation they can cause. Just wait a few seconds for it to sink in before layering the next product.
Yes. The texture is watery and sinks in immediately without leaving a greasy or sticky film. The manufacturer's measurements show 49.55% less sebum after two weeks of use, so it's especially interesting if you have a shiny T-zone. Dry skin gets a light moisture base to build on at the same time.
Somewhere cool and dry, out of direct sunlight, with the cap screwed on properly. A bathroom shelf is fine as long as the bottle isn't sitting in the shower. Avoid putting a used cotton pad back into the bottle, and use it up within twelve months of opening.
