How to use

  1. After cleansing and a spritz of mist, apply 2–3 drops to your face.
  2. Pat in gently. It absorbs quickly.
  3. Go straight to sunscreen and foundation. No separate primer needed.

For external use only. Avoid the eye area. Stop use if irritation occurs.

Good to know

When will I see a difference in dark spots?
Dark spots fade slowly. In our 4-week human test, the look of dark spots dropped by 25.54%. Give it at least 4 weeks of daily use, and wear sunscreen every day, since sun brings spots back.
Is it OK to use every day?
Yes, morning and night. It scored an irritation index of 0.00 in a skin patch test, and it already contains a stable form of vitamin C, so you don't need a separate vitamin C serum.
It feels a little sticky. Am I using too much?
Probably. 2–3 drops cover your whole face and absorb in seconds. Pat it in, then follow with moisturizer or sunscreen.
I have sensitive, breakout-prone skin. Should I try it?
Most reviewers with sensitive skin had no irritation, and it scored 0.00 in a patch test. Everyone's skin is different, so try it on a small area for 2–3 days first and add one new product at a time.

★★★★★

My skin is usually dry, so I need a lot of moisture, and this sinks in moist without stickiness. It's clear, so I thought it would dry out fast, but it spreads smoothly and the moisture lasts. Amazing. The scent and texture are nice too; it feels like feeding my skin. I love the feel most of all.

The yeolim serum feels different the moment you apply it. It's watery at first, but as you spread it, it settles in with a subtle bounce and feels like it fills skin up. A little while later my skin feels smoother, and it's moist without stickiness. My skin is sensitive and breaks out easily, but there's no stinging or warmth when I apply it. It just settles in softly. Feels like something I can use every day without worrying about breakouts ^^

I was surprised how light and soft the texture was the first time I used it. It absorbs with no stickiness, so it's great for every day. My skin has been sensitive lately, but I'm using it comfortably with no irritation. Using it consistently, my skin feels a little smoother. A perfect serum for the first step of a routine 🤍

I started out half-doubting, but after about 4 weeks my skin tone looked clearly different. People around me said it first: 'Something's different about your skin.' My skin used to look dull, and now it looks clearer and brighter. The vitamin complex seems to really work. I'd buy it again.
