started using this around 2 months ago but I still have a ton left despite using it day and night, altho I don't really use a ton of product at once. maybe like 2 small pumps for my whole face and sometimes my neck. my face feels smoother and there's a lot less redness on my cheeks. but the essence is kinda sticky and despite other people finding it moisturising I still have to layer cream on top of it but I do have suuuuuper dry skin and eczema anyway though.
