pH, irritation, pore-clogging, compatibility. We don't just show a table — we explain the 'why' in conversation.
We estimate pH range, irritation 0–10 and pore-clogging (comedogenic) 0–5 from the ingredient list.
We catch clashing combos like Retinol + AHA and duplicate Niacinamide, and suggest how to use them.
8-axis feel like tackiness and absorption, trend ingredients like Cica and Retinol, and a product grade based on ingredients.
What's this serum's pH, and does it clog pores?
It's mildly acidic (about 4.5) and pore-clogging risk is low (1/5). Fine even for acne-prone skin.
Can I use a Retinol serum with an AHA toner?
The irritation overlaps. I'd recommend alternating days (Retinol Mon/Wed/Fri, AHA Tue/Thu).
