What it does
- Supports smoother skin and a softened look of fine lines.
- A gentle, well-tolerated anti-ageing signal active.
- Works at very low use levels.
How it works
Adenosine is a naturally occurring nucleoside widely documented to support skin-cell processes linked to firmness and texture. It is recognised as an anti-wrinkle functional active in some regulatory systems and is effective at very low concentrations.
Use level
- Typical use level
- typically 0.04–0.1%
Used at low levels, commonly 0.04–0.1%. Dissolves better in warm water.
Formulation considerations
- Water-soluble; dissolves more readily in warm water, then cool.
- Effective at very low levels; broadly compatible and stable.
- Gentle and non-irritating.
What it pairs with & what to avoid
Pairs well with
- Niacinamide, peptides
- Hydrators and antioxidants
Use with care / avoid
- Over-dosing — it works at low levels
Regulatory status
Adenosine is listed in the EU CosIng database and is recognised as an anti-wrinkle functional active in some markets.
