Short answer: The best online route for melasma/dark spots is a tele-dermatology service that can prescribe a personalized combination topical (eg. hydroquinone or tranexamic acid + tretinoin or azelaic acid) plus supervised follow-up — backed up by strict sun protection. For most people the most effective online options are Curology (US) or Dermatica (UK/EU) for prescription topical programs, and broader telederm platforms (Hims & Hers dermatology, Teladoc/PlushCare/DermatologistOnCall) if you need a full dermatology consult.
Recommended services (why):
- Curology — personalized prescription creams made to order after an online questionnaire and photo review; commonly includes tretinoin, azelaic acid, or hydroquinone for hyperpigmentation; monthly follow-up and refills make it convenient.
- Dermatica — a prescription topical subscription popular in the UK/EU that commonly uses tretinoin + hydroquinone or tranexamic acid combos targeted to melasma; many users report noticeable improvement and it’s focused on pigmentation.
- Hims & Hers dermatology (and similar telederm services such as Teladoc, PlushCare, DermatologistOnCall) — these provide virtual visits with board-certified dermatologists who can evaluate complex melasma, prescribe oral treatments (eg. oral tranexamic acid when appropriate), and recommend in‑office procedures if needed.
Good OTC products you can buy online (supportive, not a substitute for prescription care):
- Sunscreen: La Roche-Posay Anthelios or EltaMD UV Physical (broad spectrum SPF 50+, physical blockers) — absolutely critical.
- Brightening serums: SkinCeuticals Discoloration Defense (contains tranexamic acid + kojic acid + niacinamide) — good for maintenance.
- Budget actives: The Ordinary Azelaic Acid 10% Suspension, The Ordinary Alpha Arbutin 2% + HA — useful adjuncts for lightening.
- Niacinamide and vitamin C serums also help as supportive ingredients.
What to expect in an effective online plan
- A prescription-strength topical combination (eg. hydroquinone 4% or 2% + tretinoin/retinoid, or topical tranexamic/azelaic acid) prescribed and monitored by a clinician.
- Strict sun protection (broad-spectrum SPF 50+, physical filters, reapplication, sun hats).
- 3–6 months of consistent use before meaningful improvement; maintenance therapy afterward.
- In some cases in‑clinic procedures (chemical peels, microneedling, certain lasers) or short courses of oral tranexamic acid may be recommended — these require an in-person or specialist consult.
Safety/time considerations
- Hydroquinone and some oral agents need medical supervision; long-term use should be monitored. Oral tranexamic acid has clotting risk and is contraindicated in pregnancy.
- Melasma can worsen with inflammation or improper laser/peel — only allow experienced providers to perform these.
- If your melasma started or worsened during pregnancy, or if it’s rapidly changing, see an in-person dermatologist.
