Glow serum for dehydrated combination skin: HEEDA Glutathione Serum
In short
I tried HEEDA Glutathione All-in-One Serum on my severely dehydrated combination skin in Korea. It absorbed without feeling sticky and left my skin feeling hydrated and bouncy before makeup, so I would consider repurchasing it.

How did it feel on dehydrated combination skin?

I have combination skin with both oily and dry areas, and I am especially prone to dehydration beneath the surface. When my basic skincare routine is lacking, I feel the dryness more strongly when applying makeup.

I placed a few drops on each cheek with the dropper and spread it out. It absorbed lightly without a sticky feeling, so the next skincare step did not feel burdensome.
After it absorbed, my skin felt as though it had been filled with moisture from within—bouncy and firm. When I used it before makeup, my skin felt prepped for makeup, and I felt that color makeup applied well too.

Were the bottle and texture easy to use?

At 30ml, it looked small at first, but after using it, it did not feel insufficient. It was also fine to carry around.

The dropper made it easy to control the amount, and it closed securely after use, so I used it without worrying about leakage. The texture felt clear, light, and like a water-glow formula.

What are the ingredients and product details?

The product information says it contains 500ppm glutathione and is formulated with niacinamide. It is also described as using liposome technology to improve absorption.

It is made in South Korea, and the label recommends using it within 12 months of opening. It is presented as suitable for all skin types, and the manufacturer also states that it completed sensitive-skin testing.
Would I repurchase this serum?

I had already been using HEEDA cleansing products, so I had expectations for the serum as well, and its feel met those expectations for me. I liked the hydrated, bouncy finish after applying it, so I would consider repurchasing it.

My partner said the side I applied it to looked like a moist steamed bun.
