Do the test as long as you would use the product. For example, if you are testing foundation wear the test patch for as long as you’d wear your foundation.
Patch test for the same amount of time you would use the product normally. So, if it is a retinol serum, you'd leave it on overnight. Vitamin C you would leave on all day. Hope this helps! 💙
Very useful thank you
thank you💗
Can I do this on my hands or something other than my face or no?
If you're testing a face product, the best place is to do the test on your face or neck. Hope this helps! 💙

If makeup products ? How long does it takes ?
Do the test as long as you would use the product. For example, if you are testing foundation wear the test patch for as long as you’d wear your foundation.
