The first step while selecting the right size of Dermicool bottle is to determine your needs. If you sweat profusely, it is best to opt for a bigger size as you will be using the powder frequently. Similarly, if you are someone who travels frequently or spends most of the time outdoors, a smaller size will be more manageable to carry in your bag. To cater all of your needs we offer it in 5 different sizes being 18g, 50g, 90g, 150g, 400g.
