Ingredient review
Sodium Menthyl Succinate
INCI: Sodium Menthyl Succinate
A gentle, non-irritating cooling ingredient that adds a pleasant chill to skincare without the strong smell or sting of menthol.
In plain English
Sodium Menthyl Succinate is a cooling agent made from menthol, the compound that gives mint its cool feel. Unlike pure menthol, it doesn't have a strong minty smell and is much less likely to cause stinging or irritation. It's used in skincare to create a refreshing, cooling sensation on the skin, which can feel soothing, especially in warm weather or after sun exposure. Think of it as a milder, more skin-friendly version of the cooling effect you get from mint.

What it is
Sodium Menthyl Succinate is a semi-synthetic compound created by combining menthol with succinic acid. It is designed to deliver a cooling sensation to the skin without the strong odor and potential irritation associated with pure menthol. It is often used as a sensory enhancer in cosmetic formulations.
How it works
It works by interacting with the skin's temperature-sensitive receptors (specifically TRPM8 receptors), which are the same receptors that respond to menthol. This interaction triggers a sensation of coolness without actually lowering skin temperature. The succinate modification makes it less volatile and less irritating than menthol, providing a longer-lasting, gentler cooling effect.
Pros
Gentle cooling
Provides a noticeable cooling sensation without the strong minty smell or stinging that pure menthol can cause, making it suitable for sensitive skin.
Versatile sensory enhancer
Can be added to a wide range of products like moisturizers, serums, and sunscreens to create a refreshing feel that consumers often find pleasant and soothing.
Cons and cautions
Sensory only
The cooling effect is purely a sensation—it does not lower skin temperature or provide any therapeutic cooling, so it won't help with actual overheating.
Potential mild irritation
Although much gentler than menthol, a small number of people with very sensitive skin may still experience mild tingling or discomfort.
Best for
- Anyone who enjoys a cooling sensation in skincare
- People looking for a gentler alternative to menthol
- Those using after-sun or foot care products
Use caution if
- Individuals with known sensitivity to cooling agents or menthol derivatives
