Hydroquinone directly inhibits tyrosinase, the enzyme your pigment cells use to produce melanin. It has been the standard of care for stubborn melasma for decades, which is why it remains the reference active for pigmentation that hasn't responded to gentler protocols.

Other brightening actives work at different points in the same process. Tranexamic acid calms the signals that trigger pigment production upstream. Kojic acid slows melanin formation through a second pathway. Niacinamide reduces how much pigment transfers between skin cells. Hydroquinone acts on the enzyme itself, which is what makes it the stronger option when pigment is deep or already established.

If you want pigment correction without hydroquinone, The Dark Spot Solution^Rx is built around tranexamic acid and can be used continuously without cycling.

It depends on your pigmentation and on what you have already tried.

If you are new to prescription brightening, or your pigmentation is mild, a board-certified dermatologist on our clinical team will usually start you on The Dark Spot Solution^Rx. It works continuously with no cycling required.

If your pigmentation is deep, has already resisted other treatments, or covers larger areas of your face, The Brightening Solutionᴿˣ is likely the right starting point.

Moderate pigmentation can go either way, and the deciding factor is usually your treatment history. If gentler options have not been tried yet, starting there is common. If they have been tried without result, hydroquinone is the next step. Your assessment determines which one fits.

Hydroquinone works by suppressing melanin production, and continuous use without breaks increases the risk of side effects, including ochronosis, a paradoxical darkening of the skin that can be difficult to reverse. Cycling is how that risk is managed.

DermClick's protocol follows standard clinical guidance: a period of active use followed by a planned break. A board-certified dermatologist on our clinical team will set your specific schedule based on your response and your skin history. During breaks, you may step down to The Dark Spot Solution^Rx, which contains no hydroquinone and can be used continuously.

Do not continue past your prescribed cycle without direction from our clinical team.

Most of your routine can stay. Gentle cleansers, fragrance-free moisturizers, and daily broad-spectrum SPF all pair well with The Brightening Solutionᴿˣ.

What you should pause: other retinoids, since you are already getting prescription tretinoin; any other product containing hydroquinone; benzoyl peroxide in the same step, since it can deactivate tretinoin and discolor when combined with hydroquinone; hydrogen peroxide products in the application area; high-concentration alpha hydroxy or beta hydroxy acids; and products containing resorcinol.

Pause waxing, laser treatments, and chemical peels on treated areas for at least one week before and one week after the procedure.

A board-certified dermatologist on our clinical team will review your routine during your assessment.

Some people notice pigmentation looking darker before it looks lighter. Temporary darkening is usually associated with insufficient sun protection, which is why daily broad-spectrum SPF 30 or higher is the single most important habit during treatment.

Stop applying and contact your DermClick care team if the darkening appears bluish or gray, or has a different color quality than your original melasma. That can be a sign of ochronosis and needs to be reviewed.

No. The Brightening Solutionᴿˣ contains both hydroquinone and tretinoin, neither of which is recommended during pregnancy or breastfeeding.

Melasma is extremely common during pregnancy, often called the mask of pregnancy, but it requires a pregnancy-safe approach, typically daily broad-spectrum SPF and trigger avoidance, with treatment starting after delivery and after breastfeeding ends.

If you are already using The Brightening Solutionᴿˣ and your pregnancy status changes, contact your DermClick care team immediately. If you are not yet a customer, our support team can help you plan timing.

Possibly. Melasma is chronic, driven by hormones, UV exposure, and genetics, and it tends to return whenever those triggers are active.

The Brightening Solutionᴿˣ is used in cycles, with maintenance on The Dark Spot Solution^Rx during breaks. Daily SPF and trigger avoidance reduce the rate of return. Some people see lasting reduction, others use ongoing cycling to keep pigmentation managed.

A board-certified dermatologist on our clinical team will set realistic expectations based on your case.

Hydroquinone is not designed for continuous, uninterrupted use. That is why The Brightening Solutionᴿˣ is prescribed with a cycling protocol rather than as an ongoing daily treatment.

The risks documented with hydroquinone are associated with unsupervised use, continuous use without breaks, high concentrations, and inadequate sun protection. Cycling guidance, dermatologist check-ins, daily SPF, and the option to step down to The Dark Spot Solution^Rx during off-cycles are how the protocol is structured to manage those risks.
