pH matters
Hi, as we all know paying attention to product's pH level is another pivotal thing in building a good skincare regime. I've been using skincare products from korean brand mostly but as I am going to add another product into my routine, a few concerns popped out on my head. So you see, I have a COSRX 96% Snail Power Essence(pH-6.9) which I'd like to pair with my retinol serum which the brand claims to have a skin-like pH(pH 5-6). Ideally you would apply essence first, then serum. In my case my essence has higher pH which means it should be applied after my retinol serum when I meant for it to go first so the retinol serum won't irritate my skin. What I am asking here is if it's ok if I go with my snail essence first? Will its pH level cancel my retinol serum's benefit? A help from derm/ skin expert would be much appreciated. Thank you in advance for the answers.
