Can b12 cause folliculitis?

Yes, high doses of Vitamin B12 can cause folliculitis (also called vitamin B12-induced acneiform eruption), which appears as red bumps and pus-filled pimples, often on the trunk and shoulders, typically resolving after stopping the supplement. This occurs because excess B12 promotes the growth of skin bacteria (C. acnes), leading to inflammation, but it usually lacks the blackheads (comedones) seen in typical acne.

What vitamin deficiency causes folliculitis?

Yes, deficiencies in Vitamin A and Vitamin C are linked to specific types of folliculitis (like phrynoderma/follicular hyperkeratosis), causing dry, bumpy skin, while low iron (iron deficiency anemia) can cause chronic folliculitis, and poor levels of other nutrients like Vitamin D and B vitamins can affect overall hair/skin health, making deficiencies a factor in some skin issues.

What clears up folliculitis?

To get rid of folliculitis, keep the area clean with antibacterial soap, apply warm compresses to soothe it, avoid shaving or tight clothes, and use over-the-counter (OTC) treatments like benzoyl peroxide; for persistent or severe cases, see a doctor for prescription antibiotics, antifungals, or steroids, as treatment depends on the cause (bacterial, fungal, etc.).
