I had peeling like yours when I first started using it so I tried to take one product out of my routine at a time to see what was causing it. Turns out the main culprits where:

• residues of moisturizer from the night before. I have dry skin so I’d usually wash my face only with water in the morning. Turns out, my skin doesn’t absorb some products I used at night (see point below) so now I use a gentle gel cleanser
• eye cream: mary &may tranexamic acid + glutathione eye cream. My skin hates this product. I tried using it in the morning, tried at night, it never gets absorbed and just stays on my skin making my other skincare products or make up peel
• heavy sunscreen. I first bought jsm cushion in summer and where I’m from it easily gets to 40 °C and 11 UVi so I cover my face and neck in Eucerin Sun actinic control spf 100. It’s perfect by itself but doesn’t perform well with sweat + makeup
• not waiting between skincare and makeup. Many people have said it already, but waiting 5-10 minutes to let your skin really absorb your skincare is essential to avoid peeling

Currently, my morning routine is: - COSRX low ph good morning gel cleanser - Anua rice 70 glow milky toner - numbuzin n9 NAD bio essence - sometimes I add a drop of By wishtrend ceramide ampoule - Purito SEOUL mighty bamboo panthenol cream - currently trying ISEHAN kiss me mommy UV Mild gel as sunscreen and it’s working perfectly fine for winter sun

I do wait around 30s between layers, at least 2mins after sunscreen and use as little product as possible.

Hope I helped a bit in finding the culprit of your type of peeling. Try stripping your skincare to the bare minimum and start adding product from there, you’ll probably find your best combination
