## In short

HEEDA Glutathione High-End Glow Serum is a 30ml Korean glow serum I used in Korea for about three weeks, before morning makeup and after evening cleansing. Its light water-glow texture absorbed quickly with almost no stickiness; I felt my dryness and dullness eased somewhat and dark spots looked a little brighter.

I used HEEDA Glutathione High-End Glow Serum for about three weeks. After trying HEEDA’s cleansing foam and cleansing balm, I decided to try the serum too.

## What are the volume and price?

Each bottle contains 30ml. At the time of writing, the product cost ₩14,900, and I wrote that I bought it for ₩17,900 including shipping. It comes in a brown glass bottle and is small enough to fit in one hand, so I also thought of it as an option for travel.

## What is the texture like, and is it sticky?

It has a light brown water-glow texture. It did not feel overly runny, yet it absorbed quickly when applied to my face and felt pleasantly adherent. Even though I do not like sticky products, I found its light absorption comfortable.

## Was it easy to use before morning makeup?

I used it before morning makeup and as the final skincare step after evening cleansing. It absorbed moisturisingly in a short time, so I did not have to wait long before applying makeup.

## How much did I use at a time?

I used the dropper to dispense the amount I needed. Usually, one pump was enough, while I used two pumps on days when my skin felt especially dry. I applied a small amount to each cheek, then gently worked it in with rolling motions.

## How did my skin change after three weeks?

After about three weeks, I felt that my dark spots looked a little brighter and that my overall dryness and dullness had eased somewhat. These are my personal observations from using the product.
