Telehealth dermatology: what's worth it
Telehealth dermatology works well for acne, melasma, mild rosacea, and anti-aging — conditions where photo-based diagnosis is reliable. It doesn't work for skin cancer screening, biopsies, or anything requiring tactile examination. Most of the value sits in the prescriptions you can't get over the counter.

Tretinoin: the centerpiece
Prescription topical retinoid. Stronger than OTC retinol by ~10-100x. Best evidence for acne, photoaging, and texture. Compounded with niacinamide, azelaic acid, or hydroquinone in many telehealth formulations. Causes initial irritation (the 'retinization' period) lasting 4-8 weeks. Effects on fine lines take 3-6 months.
Acne medications
Tretinoin + topical or oral antibiotics for inflammatory acne. Spironolactone (oral) for hormonal adult acne in women — 50-100mg/day, takes 3 months. Isotretinoin (Accutane) is highly effective but requires monthly bloodwork and iPLEDGE program enrollment — most telehealth platforms have stopped offering it post-2024.
Anti-aging vs marketing
The interventions with evidence: daily sunscreen, tretinoin, vitamin C in the morning, niacinamide. Everything else (peptides, growth factors, plant stem cells) has weak evidence. Telehealth programs that bundle 'anti-aging stacks' rely on tretinoin doing the heavy lifting; the rest is marketing.
Costs
Compounded tretinoin formulas: $25-50/month. Topical acne kit (cleanser + tret + niacinamide): $35-75/month. Oral spironolactone via telehealth: $25-40/month. The drugstore equivalent (retinol + niacinamide + SPF) costs $30-50/month but is 10x weaker than the prescription.
