Glow serum for dry skin, tested 2 weeks: HEEDA Glutathione Serum
In short
HEEDA Glutathione High-End Glow Radiance Serum is a facial serum used for dry, tight-feeling skin in Korea. I applied it morning and night for about two weeks and found it moisturizing, lightweight, and helpful for makeup adherence, though I could not separate changes in spots or redness from concurrent toning laser treatments.

Why did I add a serum for dry skin?


My face and body both tend to be very dry, so I started looking for a moisturizing product. As the weather became colder and drier, my face felt tighter after cleansing, so I decided to add a serum between my usual toner and cream.

How did the texture feel after morning-and-night use for two weeks?


For about two weeks, I applied it to both cheeks, forehead, nose, and chin after cleansing in the morning and evening. I also tested it on the back of my hand first. Even when I applied a generous amount, it felt less sticky or prone to pilling, and I did not find layering it uncomfortable.

It seemed to absorb quickly after touching my skin. It felt moisturizing without being heavy, which made it easy to use every day.


What changes did I notice after two weeks?

Rather than seeing an immediate major brightening effect, I felt that dullness had lessened and that my skin looked more radiant as moisture built up. My makeup seemed to adhere better than when I did not use the serum, and I also felt less dryness-related tightness.


However, I was also receiving toning laser treatments during the same period, so it was difficult to distinguish whether changes in dark spots or redness came from the serum alone.

What skin concerns did it suit?


I was satisfied with it when adding a moisturizing serum for dryness and a rough, dehydrated feeling. I chose it after seeing glutathione and niacinamide listed in the original product information, but the skin changes noted here are only from my personal two-week experience.
