The formula
A compounded prescription gel
Luminous is a hydroquinone-free gel for melasma and dark spots. It pairs two brightening actives with tretinoin, for people who can't use hydroquinone or want a break from it. Ours is compounded by a U.S. 503A pharmacy; compounded formulas are not themselves FDA-approved.
Kojic acid slows pigment production, tranexamic acid targets the signals that switch pigment cells on, and tretinoin speeds the turnover of pigmented surface cells.
Through ForbiddenRx, a licensed provider reviews your skin and history and decides whether this gel, and how it is used, is right for you.
Melasma and dark spots happen when pigment cells become overactive, often triggered by sunlight, visible light, heat and hormones. Because the triggers keep coming, pigment tends to return, so treatment is usually paired with daily sun protection and a longer-term plan.
Light, heat and hormones activate melanocytes. Tranexamic acid works on those activation signals.
More melanin is made and deposited. Kojic acid slows that production; tretinoin helps shed it.
Both treat pigment. Hydroquinone is the long-standing prescription standard; Luminous uses different brightening actives and contains no hydroquinone.

Some people use a hydroquinone cream for a period, then switch to a hydroquinone-free option. Your provider decides what fits your skin.
Three actives working on different steps of pigment formation.
Kojic acid reduces tyrosinase activity, the enzyme pigment cells use to make melanin.
Tranexamic acid is studied for interrupting the signals that switch pigment cells on.
Tretinoin 0.05% speeds turnover of pigmented surface cells and evens texture.
It's for adults with melasma or dark spots, especially those who can't use or want to avoid hydroquinone. A provider confirms it's appropriate.
Patchy brown pigment on the face, managed with a provider-guided plan.
People who reacted to hydroquinone or prefer to avoid it.
A maintenance option a provider may recommend after a hydroquinone course.
Sun spots and post-acne marks you'd like to fade.
Avoid it if you're pregnant, trying to conceive or breastfeeding, because it contains tretinoin. Tell your provider about broken or irritated skin, eczema, or a past reaction to kojic acid, tranexamic acid or retinoids.
