I dont say that it is a bad thing, but i normally prefer my toner’s texture to be a bit thick so that i dont have to use any cotton pads. This toner is watery, so it might be better to use cotton pads.

This product makes my skin brighter. It has chemical exfoliant that are not harsh on my skin and doesnt dry my skin too.

I think when applying the product to your face using the dropper, just make sure the tip of the dropper doesn’t touch any part of your skin to avoid contamination. Personally i would prefer a pump bottle. 
The percentage of niacinamide might be high for first timers, so if you have sensitive skin, do a test patch. 

I like the texture and how it absorbs into my skin.
I have dry skin and using this made my skin more moist.
This product contains niacinamide 10% and arbutin 2%. This two ingredients are great for for aging skin and keeps it plump. 
The packaging is an amber glass with dropper, so the product is protected from light. 

The texture is a bit sticky, but it absorbs well into my skin. So it was not a big deal. 

After using this essence, I notice that my skin is more moisturize. It also helps out with skin healing and regeneration. The mucin in this essence helps with dark spots as well. I realised that when I am older, my acne scars have a had time fading. I had an acne scar that was darkening, and it lightened after about 3 weeks. For me, this is a good progress.
