## How did HEEDA Glutathione Serum feel on combination skin?

Because I tend to choose brightening products carefully, I tried this serum with glutathione and niacinamide. Despite its high-performance-serum impression, it had a clear, water-based formula that felt light.

One pump was enough for my entire face, and there was hardly any stickiness left either on my hands or after patting it into my skin. It did not feel suffocating on the surface, which suited my combination skin well.

## How did I apply it and for how long?

I applied it morning and night after toner, then followed with essence and cream. In summer, I felt fine using this product alone, while in winter I used it before cream. Even when used morning and night, I think the 30ml bottle could last around a month and a half.

## Did my skin tone change after about a week?

After using it consistently for about a week, I felt my skin looked clearer than before and my overall tone looked a little more even. My T-zone felt hydrated, and my cheeks looked brighter. Small dark spots also seemed to fade, but that was a change I felt on my own skin.

## What about the irritation often associated with brightening products?

I experienced almost none of the stinging or tightness I had felt when using vitamin C or acid-based products in the past. If you have combination skin and use brightening products cautiously because you are concerned about irritation, my experience may be useful as a reference.
