Provide all supporting literature and research studies, publications, protocols, and analytical assessment.

Please separate data into:

o        Mechanism of Action/s (MOA) : Free radical formation after irradiation of IAA with visible light(Green Light) and inhibition of sebum secretion, Baceriocidal effect, inhibition of skin pore occlusion.

o        Chemistry/Characterization data :

 * IAA   -  Plant Auxin

            -  Cosmetic ingredient used in anti-aging product



    ? PDT (Green Light)


Activated IAA



Free radical formation  : 1) inhibitor of sebum secretion

                                                  2) Bacteriocidal effect (P.acne and S.aureus)

                                                  3) Inhibitor of skin pore occlusion

o        In vitro bioassaydata, In vivo testing (Laboratory, Animal, and Human Clinical Studies)


1.  Free radical formation after irradiation of IAA with visible light

2. Colony count reduction of P. acnes after IPL activated IAA treatment

3. Colony count reduction of S. aureus after IPL activated IAA treatment

4. Free radical formation of IAA gel and IAA solution after irradiation with visible light on day 1, day 20 and day 45


o        Clinically tested
