What does "EU Restricted" mean?

Restricted ingredients are not banned — they are allowed in cosmetic products as long as specific conditions are met:

  • Concentration limits — maximum allowed percentage in the final product
  • Product type restrictions — some ingredients are only allowed in rinse-off or leave-on products
  • pH restrictions — the finished product must stay within a specific pH range
  • Mandatory labelling — certain allergens must be listed on the packaging
  • Usage conditions — must not be combined with certain other ingredients

These limits are based on the EU CosIng database (Annex III) and are updated regularly. Products sold in the EU must comply with all applicable restrictions.

Active ingredients: Ascorbyl Glucoside, Ferulic Acid, Glycolic Acid
Ascorbyl Glucoside at pH 5.4: optimal range (5–7)
Ferulic Acid at pH 5.4: acceptable but not ideal (3–4.5 is best)
Glycolic Acid at pH 5.4: likely ineffective — above 4.5
Glycolic Acid is at pH 5.4, which is too high for optimal efficacy (3–4).

Texture & Feel

Texture & Feel

Expected texture
Liquid, cream, or powder — ranges from watery fluid to dense cream depending on coverage
SpreadabilityVery easy
AbsorptionNormal
Tackiness / ResidueVery low
Finish:Variable — matte, dewy, or natural depending on formula

Pigment-rich and blendable — designed for buildable, even coverage. Silicones create a smooth, velvety "slip" with a blurring sensory effect. Slight initial tackiness that fades into a hydrated dewy finish.
