What Discoloration Defense does
Discoloration has several causes, from sun exposure to hormones to the marks left behind by breakouts. This serum is built to address the most stubborn kinds. Used daily, it visibly reduces existing discoloration, brightens the overall complexion, and helps prevent new marks from settling in, and because it is gentle and layerable it works across the full range of skin tones, including deeper skin where many brighteners are too harsh.
The ingredients, and why this combination matters
The 3% tranexamic acid is the standout, an ingredient well regarded for stubborn, hormonally-influenced discoloration such as melasma-type patches. The 1% kojic acid brightens, the 5% niacinamide evens tone and supports the barrier while calming the skin, and the 5% HEPES is a gentle exfoliating agent that helps the surface turn over so brighter skin shows through. Together they target discoloration from more than one angle.
Who it is for
Anyone dealing with brown patches, post-acne marks, or general unevenness, on any skin tone. It is gentle enough to layer with your other actives.
How to use it
Apply morning and evening after cleansing and before moisturizer. It layers under your antioxidant and sunscreen in the day. Daily SPF is essential, because sun exposure undoes pigment work faster than anything else.
How it fits with your treatments at Bar Beauty
For pigment, the strongest results come from pairing the right in-clinic treatment with consistent home care. Discoloration Defense is the daily corrector we often pair with peels, microneedling, and Aerolase for tone, and with our melasma and hyperpigmentation plans. We will map the combination to your skin at your consult.

More questions, answered
What does Discoloration Defense treat?
Stubborn visible discoloration, including hard to treat brown patches and post acne marks. The formula combines 3% tranexamic acid, 1% kojic acid, 5% niacinamide, and 5% HEPES, and is clinically shown to improve discoloration in all skin tones in as early as two weeks.
Is Discoloration Defense safe for deeper skin tones?
Yes, it is tested across all skin tones, which matters because some pigment approaches can backfire on deeper complexions. It is one of our most recommended products for post acne marks for exactly that reason.
Can I use it alongside pigment treatments at the clinic?
Often yes, and the combination is common, a home corrector like this supporting in clinic work such as gentle laser. The sequencing matters, so tell your nurse what you are using and we will time everything properly.
Where can I buy Discoloration Defense in Toronto?
From Bar Beauty Medical at 46 Fort York Blvd in CityPlace, in clinic or online with Canada wide shipping. Choose local pickup at checkout to collect it downtown.
