These are life savers... I only use them when the pimple is matured and ready to pop (TMI sorry), or after it does so it can suck out any impurities that are still there.. and honestly it works really well for that reason. I had to buy a ton because lately i've been breaking out a lot and I tend to always touch my face so this keeps the area clean and also helps in accelerating the healing process of the pimples
