## How did it feel on dull winter skin?

In winter, my skin tone tends to look dull and redness comes up, so I looked for a brightening serum. I had previously found some products too irritating or sticky to use consistently, but this one spread as lightly as water while still feeling hydrating.

The dropper made it easy to control how much I used, and not much product got on my hands, so it was easy to use every day. Even when I applied it before makeup, I personally found that it pilled very little.

## Did it feel gentle on somewhat sensitive skin?

My skin tends to flare up when I use serums that feel heavy or very oily. This serum felt comfortable without stinging when I applied it, and its scent was close to fragrance-free, so it felt less burdensome.

On dry days, I layered on another application. At those times, my skin felt less tight and seemed to retain hydration longer.

## What changes did I notice after about two weeks?

After using it for about two weeks, I noticed changes in the evenness of my skin tone first, followed by traces of blemishes and redness. The faint redness around my cheekbones, old blemish marks, and overall dullness all seemed more settled than before.

When I looked in the mirror, the contrast of blemishes that had stood out seemed reduced, and my skin also looked clearer. However, these are personal impressions from my own skin.
