If you're using more product than necessary, you are not only wasting it, but you can also dry out or irritate your skin. Your skin can only absorb so much—so don't overdo it babes (we know you've made this mistake, we do have too!).
Here's a lovely, little info-graph we made for you to help guide you—enjoy!
Keep this in mind next time you are doing your evening / morning routine.
NOTE: these amounts are a basic guideline only. Only you know what works best for your skin. Be thrifty and only use how much is necessary to ensure there is no wastage. In skincare, less is more.
