Hello! You can start with a simple routine (Cleanser, Toner, Moisturizer, Sunscreen / Masks) 😊 Maybe you can also explore retinol for her since they’re known to be good with anti-aging.
In the meantime, for starters, my reco would be to check out the Innisfree Pore Brightening line 😊 For exfoliators and retinols, you can search for brands /
products here on picky that are best picked for you ✨ I personally use the Cosrx BHA Blackhead Power Liquid and Cosrx AHA BHA Vitamin C Daily Toner as exfoliators
