What TNXA-Shot does
It is made for discoloration that hangs on: dark spots from sun exposure, darkened marks left behind by breakouts, and general unevenness. In SkinCeuticals’ testing it visibly reduced discoloration by up to 20%, brightened skin by up to 27% and visibly reduced the look of darkened acne scars by up to 18%. SkinCeuticals also had it physician-tested to complement laser treatments, which is how we see it as well: daily home care that backs up the work done in the clinic.
The ingredients, and what each one is there for
Tranexamic acid at 5% does the heavy lifting on persistent discoloration and overall brightness. Niacinamide, also called vitamin B3, at 4% helps visibly reduce discoloration. SkinCeuticals adds a 1% alpha-amino acid derivative to help correct hormonally driven discoloration, and dandelion root extract, an antioxidant-rich botanical that helps shield skin from environmental triggers. The formula is paraben-free and hydroquinone-free. It does contain a hypoallergenic fragrance, so it is not a fragrance-free product.
Who it is for
Anyone dealing with persistent dark spots, post-acne marks or uneven tone. SkinCeuticals lists it as suitable for all skin tones, including deeper complexions, which matters because some brightening approaches can be harder on deeper skin.
How to use it
Twice a day, put 4 to 6 drops on clean fingertips and gently press them evenly into the skin of your face. In the morning, follow with a broad-spectrum sunscreen, and limit sun exposure while you are using it. Daily sunscreen is the step people skip, and it is the step that decides whether dark spots stay faded.
TNXA-Shot or Discoloration Defense?
Both are SkinCeuticals tranexamic acid serums. Discoloration Defense pairs 3% tranexamic acid with 1% kojic acid, 5% niacinamide and 5% HEPES. TNXA-Shot raises tranexamic acid to 5% and pairs it with 4% niacinamide, the alpha-amino acid derivative and dandelion root extract. If you are not sure which one suits your skin, ask us at your consultation.
How it fits with your treatments at Bar Beauty
Pigment responds best to a plan that pairs the right in-clinic treatment with steady home care. TNXA-Shot is the kind of daily corrector that sits alongside Aerolase sessions for tone and our melasma and hyperpigmentation plans. Tell your nurse or aesthetician what you are using so we can time it around any treatment.
