About this formula
Azelaic acid is unusual in that it addresses the appearance of redness, uneven tone and blemish-prone skin at the same time. Threshold pairs 12% azelaic with 2% tranexamic acid for the marks blemishes leave behind.
The suspension is deliberately light — most azelaic products are thick and grabby under makeup. This one is not. Suitable for daily use, morning or evening. Net contents 30 ml (1.0 fl oz).
How to use
- 1Once or twice daily after cleansing.
- 2A pea-sized amount over the whole face, or spot-applied to marks.
- 3A brief warm tingle on first use is normal and settles within a week.

“I bought Threshold Azelaic 12% on the strength of the disclosed percentages and it is the first time a product has done exactly what the page said it would.”
“Took about six weeks before I could see it, which the page did warn me about. Glad I did not give up at four.”
“Third bottle. The packaging keeps it stable much longer than the clear-bottle version I used before.”
