Botox Injection During Active Acne
Botox injections can be safely administered in patients with active acne, as there are no contraindications to botulinum toxin use in the presence of active acne lesions, and emerging evidence suggests botulinum toxin may actually provide therapeutic benefit for inflammatory acne through reduction of sebum production and inflammation. 1, 2
Safety Profile and Contraindications
The established contraindications for botulinum toxin injections include hypersensitivity to the toxin, active infection at the injection site (such as impetigo or herpes), active tuberculosis, systemic fungal infection, and pregnancy—but active acne is notably absent from this list. 3
Active acne lesions do not constitute an active infection requiring avoidance of injection, as acne is primarily an inflammatory condition involving follicular hyperkeratinization and Cutibacterium acnes colonization rather than an acute bacterial infection. 1
The only scenario requiring caution would be if there is suspected superinfection of acne lesions (indicated by painful lesions, yellow crusts, or discharge), in which case bacterial culture should be obtained and appropriate antibiotics administered before proceeding with elective cosmetic procedures. 3
Emerging Therapeutic Role of Botulinum Toxin in Acne
Recent evidence demonstrates that intradermal botulinum toxin-A injection can serve as an adjuvant treatment for acne vulgaris, with one split-face study showing significant reduction in comedones on the botulinum toxin-treated side compared to tranexamic acid. 1
A 2022 study using "Microbotox" (a specific dilution of onabotulinum toxin A) in 35 patients with mild-to-moderate acne showed excellent satisfaction with no immediate or delayed complications, suggesting botulinum toxin may have direct therapeutic effects on acne through modulation of sebaceous gland activity. 2
The proposed mechanism involves botulinum toxin's effects on various skin cell types beyond neuromuscular junctions, potentially reducing sebum production and inflammatory mediator release. 2
Practical Considerations for Injection Technique
When injecting botulinum toxin in areas with active acne, avoid injecting directly into inflamed papules or pustules, instead targeting the surrounding normal skin to achieve the desired cosmetic effect while minimizing local trauma. 3
For patients with larger acne nodules in the treatment area, consider intralesional corticosteroid injection (triamcinolone acetonide 3.3-10 mg/mL) to these specific lesions prior to or concurrent with botulinum toxin treatment to rapidly reduce inflammation and prevent scarring. 3
Use standard sterile technique as with any injection procedure, ensuring the skin is properly cleansed with antiseptic solution before injection. 3
Concurrent Acne Management
Patients receiving botulinum toxin who have active acne should be on appropriate acne therapy based on severity: topical retinoid plus benzoyl peroxide for mild acne, or oral antibiotics (doxycycline 100 mg daily) plus topical retinoid and benzoyl peroxide for moderate-to-severe inflammatory acne. 4, 5
The American Academy of Dermatology strongly recommends limiting systemic antibiotics to 3-4 months maximum and always combining with benzoyl peroxide to prevent antibiotic resistance development. 3, 4
For female patients with hormonal acne patterns, consider spironolactone 25-200 mg daily or combined oral contraceptives as alternatives to antibiotics, which can be continued safely during botulinum toxin treatment. 4
Common Pitfalls to Avoid
Do not delay botulinum toxin treatment solely due to the presence of active acne, as this is not a contraindication and may unnecessarily postpone desired cosmetic outcomes. 1, 2
Avoid injecting through areas with suspected bacterial superinfection (purulent drainage, excessive tenderness, or systemic signs), as this represents true active infection requiring treatment before elective procedures. 3
Do not assume that botulinum toxin alone will treat the acne—patients still require appropriate evidence-based acne therapy with topical retinoids, benzoyl peroxide, and systemic agents as indicated by severity. 3, 4
