I've never really used toner except for a few years as a teenager.
Due to my love of Trilogy, I wanted to try this. The spray bottle was appealing also, as I knew it would be convenient and also wouldn't be too strong and thus drying.
It is great. I use it before moisturiser and makeup in the morning, and after cleansing and before rosehip oil in the evening. It is also nice as a setting spray, or on a hot day.
It is very refreshing and I don't think I could go without it now - BUT it is not a toner in the traditional sense. It doesn't dry the skin and it won't remove any trace amounts of anything on your skin. But it's hydrating (as it says) and refreshing, and I think it's just a nice touch. It has seemed to keep my skin balanced - since using this I've noticed that my skin is less oily during the day, but still nice and hydrated.
I strongly recommend this, but it isn't essential until you use it and get addicted to it, like me! It's well worth the price, as it is a spray bottle so there's no wastage and lasts for ages. Again, it can be used as a toner, setting spray or just as a refreshing mist.
I have used Trilogy products for a number of years now but in particular the hydrating mist toner. It is so convenient, you just spray it on and don't need to use cotton wool or wipes to apply. The scent is heavenly and makes your skin feel so fresh. I recommend this product without hesitation.
