the curriculum without modification but may require assistance in the school setting. Thismay
include conditions such as ADHD, diabetes, or migraines.

C.generate free radicals to oxidize proteins in the cell wall of Cutibacterium acnes.
D.work within the cell ribosomes to alter upstream signals affecting inflammatory pathways.
A. normalize desquamation of the follicular epithelium.
The therapeutic objectives in the management of acne vulgaris are to reduce sebum
production,prevent formation of microcomedones, suppress Cutibacterium acnes (formerly
Propionibacterium acnes), and reduce inflammation to prevent scarring.
Topical retinoids, vitamin A derivatives that bind to retinoid receptors in the skin, are a
keycomponent of primary acne management. Topical retinoids normalize desquamation of
thefollicular epithelium to prevent new formation of microcomedones, the precursors of
bothcomedonal and inflammatory lesions. Additionally, retinoids promote clearing of
existingmicrocomedones and work within the nucleus to alter downstream signals that
affectinflammatory pathways.
