Stay out of the sun for the next 24 hours, and make sure to always use your SPF any time you had out for the day!
Peels provide a LOT of exfoliation, so skip your other exfoliating products (acids, retinols +scrubs) for the next 5-7 days.
Feeling dry or experiencing mild flaking for the first week is normal, but you must keep your skin EXTRA hydrated during this time. Drink lots of water, use moisturizer and work more hydrating and healing products into your daily routine.
