Pyridoxine Serinate
INCI: Pyridoxine Serinate
A gentle, dual-action ingredient that combines vitamin B6 with serine to help calm irritation and support a healthy skin barrier.
In plain English
Pyridoxine serinate is a lab-made ingredient that pairs vitamin B6 (pyridoxine) with the amino acid serine. Vitamin B6 is known for its role in skin repair and soothing, while serine is a natural moisturizing factor that helps keep skin hydrated and comfortable. Together, they work to calm redness and support the skin's outer barrier without being harsh or irritating.

What it is
A semi-synthetic compound formed by combining pyridoxine (vitamin B6) with serine, an amino acid naturally found in the skin's moisture barrier.
How it works
Pyridoxine helps regulate skin cell turnover and reduces inflammatory signals, while serine acts as a humectant, drawing moisture into the skin and supporting the natural moisturizing factor. The combination helps soothe irritation and maintain a healthy, balanced skin surface.
Pros
Gentle soothing
Helps calm redness and irritation without stinging or drying, making it suitable for sensitive skin types.
Barrier-friendly hydration
Serine supports the skin's natural moisture barrier, helping to keep skin comfortable and hydrated over time.
Cons and cautions
Limited research
There are few peer-reviewed studies specifically on pyridoxine serinate, so its long-term benefits are not as well-documented as more common soothing ingredients.
Mild effect
It is a gentle ingredient, so it may not provide enough soothing power for those with significant inflammation or skin conditions.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, non-irritating soothing ingredient
Use caution if
- Individuals with a known allergy to vitamin B6 or serine (rare)
