Side Effects
HGH
Water retention and fluid accumulation
Joint pain and stiffness
Carpal tunnel syndrome (usually resolves with dose reduction)
Headaches
Numbness/tingling in hands
Tretinoin
Peeling and flaking (retinoid dermatitis), especially in the first 2-6 weeks
Erythema (redness) and skin irritation at the application site
Dryness and tightness of the skin
Increased photosensitivity (heightened susceptibility to sunburn)
Initial acne purging (transient worsening of breakouts in weeks 2-6)
Contraindications
Active cancer (may accelerate tumor growth)
Acute critical illness (increased mortality in ICU patients)
Closed epiphyses in children (for growth promotion)
Pregnancy/breastfeeding
Pregnancy and women planning to become pregnant (tretinoin is a known teratogen; oral retinoids cause severe birth defects, and while topical absorption is minimal, it is contraindicated as a precaution)
Breastfeeding (safety not established for topical tretinoin during lactation)
Known hypersensitivity to tretinoin, other retinoids, or any formulation excipients
Active eczema, rosacea, or severely compromised skin barrier at the application site
Concurrent use of other strong topical irritants without medical supervision (e.g., benzoyl peroxide at high concentrations on the same area at the same time)
