When I applied two to three drops at a time, it absorbed relatively quickly and did not feel like it sat on top of my skin. It did not feel irritating even when layered, and the scent was not strong.

After letting it absorb on the back of my hand and face, it felt like it adhered transparently. It seemed to absorb quickly after application, so there was little pilling when I used it before makeup, and it was easy to use both morning and night.

What were the bottle and application method like?

According to the original post, it was described as containing glutathione and niacinamide. I sometimes mix niacinamide products with other skincare products, but I used this one on its own.
