Ingredient review
Ethyl Nicotinate
INCI: Ethyl Nicotinate
Ethyl nicotinate creates a temporary warm flush on the skin by widening blood vessels, often used for a plumping or tingling effect, but it can cause irritation in sensitive skin.
In plain English
Ethyl nicotinate is a lab-made ingredient that makes your skin feel warm and look flushed for a short time. It works by opening up tiny blood vessels near the skin's surface, which increases blood flow. This can make your skin look temporarily fuller or more radiant, but the effect is only cosmetic and not a long-term improvement. It's often added to products that promise a 'glow' or a plumping sensation, like lip glosses or facial serums.

Ethyl Nicotinate can be useful, but watch for some irritation potential.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Ethyl Nicotinate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

What it is
Ethyl nicotinate is a synthetic ester derived from nicotinic acid (a form of vitamin B3). It is not a vitamin itself but a chemical relative designed to trigger a specific skin response.
How it works
When applied to the skin, ethyl nicotinate is absorbed and converted to nicotinic acid, which then stimulates the release of prostaglandins. These compounds cause the blood vessels in the skin to dilate (widen), increasing blood flow to the area. This results in a visible redness (flushing) and a warm, tingling sensation that typically lasts 15–30 minutes.
Pros
Immediate visible glow
Within minutes of application, ethyl nicotinate increases blood flow to the skin's surface, creating a noticeable flush that many associate with a healthy, radiant complexion.
Sensory experience
The warm, tingling sensation can make a product feel more active or effective, which some users find satisfying and invigorating.
Cons and cautions
Temporary effect only
The flush and plumping last only 15–30 minutes. There is no evidence that ethyl nicotinate provides any lasting improvement to skin health, texture, or hydration.
Irritation risk
Ethyl nicotinate is a known vasodilator that can cause stinging, burning, and excessive redness, particularly in those with sensitive skin or conditions like rosacea.
Best for
- People who enjoy a temporary warm or tingling sensation from their skincare
- Those looking for a short-term plumping effect before an event
Use caution if
- Individuals with sensitive, reactive, or rosacea-prone skin
- Anyone with broken or irritated skin, as it can cause stinging
Usage tips
Safety summary
Ethyl nicotinate is generally considered safe for cosmetic use at low concentrations, but it is a known irritant and vasodilator. It can cause temporary redness, warmth, and stinging, especially in sensitive individuals. It is not recommended for daily use on sensitive or compromised skin. The ingredient is not linked to long-term health risks, but its effects are purely cosmetic and temporary.
Research notes
Research on ethyl nicotinate primarily focuses on its vasodilatory properties. Studies confirm that topical application increases blood flow and skin redness within minutes, with effects lasting up to 30 minutes. There is limited research on long-term cosmetic benefits, and most evidence is based on its mechanism rather than clinical efficacy for skin health.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for cosmetic use in the EU, US, and many other regions. It is not a drug ingredient and is regulated as a cosmetic ingredient. No specific concentration limits are set, but typical use is low (under 2%).
- Common uses
- Facial serums, Body lotions, Lip plumpers, Hair growth tonics
- Environmental note
- Ethyl nicotinate is synthetically produced and not known to have significant environmental persistence or bioaccumulation concerns at cosmetic use levels.
Good to know
- Ethyl nicotinate is sometimes confused with niacinamide, but they work very differently. Niacinamide is a stable form of vitamin B3 that strengthens the skin barrier without causing flushing.
- The flushing effect is dose-dependent; higher concentrations increase the intensity and duration of the sensation.
