Functional hydro-soluble azelaic acid

anti-acne – antiseborrhoeic – skin lightening

INCI name

Polyglycerin-6, Azelaic Acid, Betaine


PG6 ACTIVE AA-BET C® is an exclusive form of natural azelaic acid acting as an effective anti-acne, sebum-normalising and skin lightening agent.
Thanks to a special synthesis reaction, this stable form of azelaic acid (whose concentration within the substance is up to 40%) can be incorporated in many different applications  at a wide pH range.
PG6 ACTIVE AA-BET C® can be quickly solubilized in water in a cold process allowing formulators to create either transparent water based gels or OW/WO emulsions.
  • It has bacteriostatic, sebum-normalising and anti-inflammatory properties that make it particularly suited for treating acne and impure skin. It has also been shown to be effective at treating rosacea and erythema. Azelaic Acid has a lightening effect on dark spots while the glycine moisturizes the skin and makes it more elastic.
  • It is completely soluble in water and hydroalcoholic mixtures, stable over a wide pH range, active substance carrier, compatible with non-ionic, anionic and cationic solutions. 
  • It has solvent capacities, good stabilizing effect in emulsions and dispersing power with an high surface hygroscopicity which provides a long-lasting moisturizing action.


Natural Azelaic Acid delivered in polyglycerol medium.


In-vivo tests showed depigmentation and anti acne activity.

The degree of pigmentation of the facial spots analysed had improved with respect to the baseline: 7.5% after 15 days and 15% after 30 days. The product demonstrated also that it progressively reduced the number of acne lesions during treatment. The most important action was on the pustules, where the decrease reached statistical significance after 30 days of treatment with respect to the baseline values, and not modifying the sebaceous secretion or the pH of the skin, demonstrating that it does not alter the normal physiological conditions of the skin: 12% improvement in papular lesions after 15 days and 19% after 30 days.
