Erythrulose
Ingredient Info
Erythrulose is a naturally derived sugar that works as a self-tanning agent. Like DHA (dihydroxyacetone), it reacts with amino acids in your skin to create a brown color, but it typically develops more slowly and may last slightly longer than DHA alone.
Benefits
- Creates a gradual, natural-looking tan without sun exposure
- Often used alongside DHA to extend tan duration and improve color evenness
- Generally well-tolerated with low irritation potential
- Semi-permanent color that fades as skin naturally sheds dead cells
Potential concerns
- May cause contact dermatitis or allergic reactions in sensitive individuals
- Can cause unwanted pigmentary changes or streaking if not applied evenly
- Provides no UV protection—sunscreen use is still essential
Science: Erythrulose is used in approximately 38% of commercial self-tanning products, typically combined with DHA. It works through the same Maillard reaction mechanism as DHA, producing brown pigments (melanoidins) that deposit in the outer skin layer. Clinical data on adverse effects show self-tanners overall have a low incidence of skin reactions (roughly 2%), though contact dermatitis remains a possible concern in susceptible individuals.
