Ingredient review
Myristyl Nicotinate
INCI: MYRISTYL NICOTINATE
A niacin-derived ingredient that temporarily increases blood flow to the skin's surface, often used for a plumping or warming effect.
In plain English
Myristyl nicotinate is a form of vitamin B3 (niacin) that's been modified to work on the skin's surface. When applied, it causes a temporary increase in blood flow to the area, which can make the skin look flushed, feel warm, and appear temporarily firmer or plumper. This is why it's sometimes found in products meant to reduce the appearance of cellulite or give lips a fuller look. The effect is not permanent and is more about sensation and short-term appearance than long-term skin health.

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 Myristyl Nicotinate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

What it is
Myristyl nicotinate is a fatty alcohol ester of niacin (vitamin B3). It is a semi-synthetic ingredient designed to deliver the vasodilating (blood-vessel-widening) properties of niacin directly to the skin without the strong flushing that oral niacin can cause.
How it works
When applied topically, myristyl nicotinate is absorbed into the skin and converted to niacin, which then triggers the release of prostaglandins—chemicals that cause blood vessels to widen. This increases blood flow to the skin's surface, resulting in a temporary warming sensation, redness, and a plumping effect. The increased circulation can also help other active ingredients absorb better.
Pros
Temporary plumping effect
Increases blood flow to the skin, which can make fine lines and wrinkles appear less noticeable for a short time.
Enhances product absorption
The increased circulation may help other active ingredients in the same product penetrate the skin more effectively.
Cons and cautions
Can cause redness and stinging
The vasodilation effect can lead to noticeable flushing, warmth, or a stinging sensation, which may be uncomfortable for some users.
Short-lived results
The plumping and firming effects are temporary, lasting only a few hours, so it is not a long-term solution for skin concerns.
Best for
- People looking for a temporary plumping or firming effect for a special occasion
- Those who enjoy a warming or tingling sensation in their skincare routine
Use caution if
- Individuals with sensitive, reactive, or rosacea-prone skin
- Anyone with broken, sunburned, or irritated skin
Usage tips
Safety summary
Myristyl nicotinate is generally safe for topical use in cosmetics at concentrations up to 2%. The main safety concern is skin irritation, including redness, stinging, and flushing, which is usually temporary and dose-dependent. It should be avoided on damaged or sensitive skin. No serious long-term safety issues have been reported.
Research notes
Research on myristyl nicotinate is limited but consistent with its mechanism as a vasodilator. Studies show it can increase skin blood flow and improve the appearance of cellulite temporarily when combined with other ingredients. There is no strong evidence for permanent skin changes or anti-aging benefits.
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 active.
- Common uses
- Anti-cellulite creams, Firming lotions, Scalp treatments, Lip plumpers
- Environmental note
- Myristyl nicotinate is semi-synthetic, derived from natural fatty acids and niacin. Its environmental impact is not well-studied, but it is not known to be bioaccumulative or toxic to aquatic life at typical cosmetic concentrations.
Good to know
- Myristyl nicotinate is different from niacinamide; niacinamide is a stable form of vitamin B3 that does not cause flushing.
- The warming sensation is normal and usually fades within 30 minutes to an hour.
- It is often combined with caffeine in anti-cellulite products for a synergistic effect.
