Glutathione serum for dull skin, AM/PM test: HEEDA 30ml

In short

HEEDA Glutathione Brightening Tone Care Glow Serum is a 30ml Korean skincare serum I used morning and night for dull-looking skin. Its rich texture felt comfortable under makeup with little stickiness, though daily twice-a-day use could finish a bottle in about a month.

Was it low in stickiness before morning makeup?

Previous brightening serums felt sticky or tacky when I applied makeup, so I used them only at night. With this product, I spread one or two pumps over my whole face after toner and skin in the morning, and found it relatively comfortable under makeup.

At night, I used the same amount, spreading it more slowly as if massaging it in and finishing with cream. I felt that my skin stayed moisturized until the next morning.

How did the texture and bottle feel?

The serum in the 30ml bottle looked dark brown, and it felt concentrated enough that even a nail-sized amount could be spread across my face. I adjusted the amount with one or two pumps.

The dropper-pump bottle made it easy to dispense a measured amount. It initially felt like a rich texture, then seemed to melt along my skin texture when rubbed in; absorption felt faster when I applied it as if massaging it in.

How did my skin seem after two to three weeks?

After using it, I felt that my skin tone looked brighter and more lively. My previously dull-looking face seemed to have a natural glow, and I felt that the brighter-looking tone also helped when applying makeup.

Liposomal glutathione and niacinamide were mentioned as key ingredients, and while using it, I had the impression that my skin texture looked more refined and clearer. This is my personal observation from using the product.

What was the downside for daily use?

I counted its low stickiness and ease of use both morning and night as advantages. However, because it is 30ml, I wrote that using it every day in the morning and evening could use up about one bottle a month.

The original post did not state a specific price. I did not feel that the cost was too burdensome and plan to repurchase it.
