When Used Together
Using AHA and BHA together at high concentrations risks over-exfoliation and barrier damage.
Alternate use — AHA one day, BHA the next.
[Class rule] AHAs increase photosensitivity — always follow AHA use with broad-spectrum SPF during the day.
Apply SPF 30+ every morning when using AHAs.
[Class rule] Combining AHA and BHA increases exfoliation beyond what most skin can tolerate.
Use on alternate days or choose one.
[Class rule] BHAs can mildly increase photosensitivity — daily SPF is recommended.
Apply SPF 30+ every morning when using BHAs.
Niacinamide reduces post-BHA redness while salicylic acid unclogs pores — excellent acne-fighting duo.
[Class rule] Humectants under SPF maintain skin hydration and improve sunscreen adherence.
