[Product Question] has anyone used these two products?

I found these for an amazing clearance price at Target so I just had to try them. I was wondering if anyone has experience with them? Snail mucin made my skin breakout in the past so I’m scared but excited to try this one. And I’ve never used a vitamin C before so I’m not sure how/when to use it in my routine. My current routine is: \[both am & pm\] Byoma milky toner, La Roche Posay double repair moisturizer, and Torriden dive in soothing cream for around my eyes(temporary til I buy eye cream, La roche Posay gives me milia there so this is way lighter). Plus tret once a week
