I’ve always purchased the 200ml one and decided to purchase the large one. This is a huge bottle that can last you 6m or more depending how often you use it.
Myself I found this toner mostly hydrating, it is very watery and easy to layer - which is nice as I tend to layer my toners 5 times. This product is super gentle on my skin, never stung or hurt my skin. Really needed in this hot, humid weather.
