What Is Hexyl Nicotinate?
Hexyl nicotinate is a synthetic compound derived from niacin (vitamin B3). It is a lipophilic (fat-soluble) ester that penetrates the skin relatively efficiently, making it useful in topical formulations.
In skincare, hexyl nicotinate functions primarily as a vasodilator—a substance that widens blood vessels in the skin. This increased blood flow can support delivery of oxygen and nutrients to the skin, whilst also acting as an emollient to help maintain skin hydration and smoothness.
How It Works
Hexyl nicotinate works by triggering vasodilation—the widening of blood vessels in the dermis. When applied topically, it penetrates the skin barrier and acts on dermal blood vessels, causing them to dilate and increase blood flow to the area. This enhanced circulation can deliver more oxygen and nutrients to skin cells.
The ingredient also functions as an emollient, meaning it helps soften and smooth the skin by reducing water loss and creating a protective layer on the skin surface. The degree of vasodilation can vary between individuals and may occur with minimal visible redness in some cases.
Clinical Evidence & References
Research demonstrates that hexyl nicotinate reliably induces vasodilation in healthy skin when applied topically. Studies using laser Doppler measurements show a dose-related increase in skin blood flow, though the visible redness (erythema) varies considerably between individuals—some people experience significant vasodilation with minimal visible redness.
Evidence also suggests that skin permeability and responsiveness to hexyl nicotinate can be influenced by other skincare products used concurrently, particularly moisturisers containing humectants or high lipid content. However, long-term efficacy data for anti-ageing or other specific skin concerns remain limited, and most research has been conducted on small sample sizes of healthy volunteers.

How to Use
Hexyl nicotinate is typically found in serums, lotions and moisturisers at low concentrations. If you have sensitive skin or are new to vasodilating ingredients, start with occasional use and monitor your skin's response. It can be used alongside other skincare products, though the order of application and choice of moisturiser may influence how your skin responds. Consistent use over several weeks may be needed to assess any cumulative benefits.
