FAQs About Hexyl Nicotinate
Why does The Ordinary Glycolic Acid Toner cause tingling?
Hexyl nicotinate is one of the contributing factors — it's a vasodilating agent that causes a mild warming or tingling sensation. The glycolic acid itself also contributes to the sensation.
Is hexyl nicotinate the same as niacinamide?
No — they are both derived from Vitamin B3 but have very different functions. Hexyl nicotinate is a vasodilator that causes surface warming. Niacinamide is a multipurpose active for pores, tone, and barrier support.
