Dry pink kinda flaky patches from corners of mouth extending down about half an inch.
I've recently begun a twice daily regimen to help with dark spots on my upper lip and between eyes. after washing and toner I use a dark spot correcting serum followed by an SPF 30 day cream. I'm noticing 2 dry flaky patches that are a little pink. starting in each corner of my mouth and extending down about half an inch. could it be due to the new products? and if so, is this a common reaction? what should I be using instead?
