Verbatim response from ChatGPT
Short answer: the best “online” treatment for melasma is a tele-dermatology service that can prescribe a tailored combination regimen (usually a bleaching agent ± retinoid ± anti‑inflammatory) and monitor you — plus medical‑grade sunscreen. That gives safer, faster, and more reliable results than OTC products alone.
Recommended services (by name, and why)
- Curology (US) — well‑known telederm platform that creates personalized prescription creams (tretinoin, azelaic acid, other actives). Good for ongoing management and follow‑up.
- Dermatica (UK/Europe/Spain) — built specifically for hyperpigmentation; compounds prescription combos (tretinoin + hydroquinone or azelaic acid, topical tranexamic acid options) and focuses on melasma protocols.
- Apostrophe / ApostropheMD (US) — connects you with board‑certified dermatologists who can prescribe hydroquinone, Tri-Luma, tretinoin, etc.; good if you want a clinician-reviewed regimen without an in‑person visit.
- PlushCare / tele‑derm services (US & many regions) — if you prefer a real‑time video visit with a board‑certified dermatologist for complex melasma (useful before starting oral tranexamic acid or procedures).
Key prescription treatments they commonly use (you’ll need a clinician):
- Triple combination cream (hydroquinone 4% + tretinoin + low‑potency steroid), e.g., Tri-Luma (effective first‑line for many melasma cases).
- Topical hydroquinone (prescription 4%) or azelaic acid (15% prescription; The Ordinary 10% azelaic acid is a decent OTC adjunct).
- Topical tretinoin or adapalene to increase turnover.
- Topical or oral tranexamic acid (oral is used in resistant cases but requires physician supervision for clotting risk).
Important OTC / adjunct products (buyable online)
- Sunscreen: EltaMD UV Clear SPF 46 (excellent for melasma-prone skin), La Roche‑Posay Anthelios, or ISDIN Fusion. Daily, broad‑spectrum, high SPF is essential.
- Vitamin C serum: SkinCeuticals C E Ferulic (highly studied) or more affordable Vitamin C serums for antioxidant and brightening support.
- Azelaic acid: The Ordinary Azelaic Acid 10% — helpful and well tolerated.
- Retinoid: Differin (adapalene) OTC if you can’t get prescription tretinoin immediately.
Cautions
- Melasma is often hormonal and chronic; improvement often takes months and relapse is common if treatment or sun protection stops.
- Hydroquinone should be used under a clinician’s guidance (risk of ochronosis with incorrect long‑term use).
- Lasers/peels can help but can also worsen melasma, especially on darker skin — do not get aggressive laser treatments without an experienced pigment dermatologist.
- Oral tranexamic acid can be effective for resistant melasma but needs medical screening for clotting risk.
If you want a tailored recommendation, tell me:
- Your country (so I can suggest services available to you), and
- Your skin tone / Fitzpatrick type and whether you’re on hormonal meds or pregnant/planning pregnancy (affects choices).
