Melasma and Hyperpigmentation: Compounding Options in Etobicoke

Understanding darker skin patches, and what a compounding pharmacist can and cannot do

What Is Melasma and Hyperpigmentation?

Melasma is a common skin condition that causes brown or grey-brown patches, usually on the face. Sun exposure, hormonal changes such as pregnancy or some contraceptives, and genetics can all play a role.

Other kinds of hyperpigmentation can follow skin injury or inflammation. Because different causes need different approaches, a prescriber’s assessment comes first.

Where Compounding May Fit

Commercial products come in set strengths and formats. Sometimes a prescriber wants something different: another concentration, several ingredients in one preparation, or a base suited to sensitive skin. In those cases the prescriber can write a prescription for a compounded preparation, and our pharmacists prepare it to those specifications.

Compounding is not a first step and not a substitute for an assessment. Whether a compounded preparation is appropriate is your prescriber’s decision, made after considering your history and the commercial products already available.

Please note: We do not promote specific compounded preparations or ingredients to the public. Your prescriber decides what, if anything, to prescribe.

Questions to Bring to Your Appointment

  • When did the patches appear, and have they changed?
  • Do they darken with sun exposure, pregnancy or hormone-containing products?
  • What sun protection do you use daily?
  • Are you pregnant, planning a pregnancy or breastfeeding?
  • Which medications and skin products are you using now?

When to See a Prescriber Promptly

See a physician or nurse practitioner if a dark patch is new, changing in shape or colour, itchy, raised or bleeding. Those changes should be assessed promptly to rule out other conditions. This page is educational and does not replace a medical assessment.

Melasma and Hyperpigmentation FAQ

Can a pharmacy compound a preparation for melasma and hyperpigmentation without a prescription?

No. A compounded preparation is made against a prescription from an authorized prescriber such as a physician or nurse practitioner.

Does sun protection matter?

Sun exposure is a well-recognized trigger for darker patches. Ask your prescriber what daily sun protection suits you.

Is every dark patch melasma?

No. A new or changing spot needs a medical assessment before anything else.

Does insurance cover compounded preparations?

Coverage varies by plan. Call us with your prescription and we will check what your plan allows before preparing it.

How long does preparation take?

Many preparations are ready within 24–48 hours of receiving a complete prescription, though timing depends on the preparation and ingredient availability. We will confirm when you call.

Do you offer delivery?

Yes, we deliver across the GTA. Call (647) 348-2323 for details and timing.

When should I contact my prescriber or pharmacist?

Contact them if you notice a reaction, new symptoms or questions after starting a prescribed preparation. For difficulty breathing or swelling of the face, call 911.
