Ask for more information, SPF Protect Ultra ™ II if put in the amount of 30 % -> SPF =90 PA++++
If wearing 15% SPF =50 PA ++
1. If I add 10%, has the company ever measured the SPF PA value?
2. If I put MatteSilica 5S™ to reduce oiliness, viscous and easy to spread, will it affect the action or efficiency of the Active ingredients mixed in the Oil phase?
such as MSH White ™ ( Undecylenoyl Phenylalanine), WhiteCumin ™ ( Tetrahydrodiferuloylmethane)
,Hi- Glabridin ™ Licorice Extract (Glabridin 40%) , TXC ™ ( Cetyl Tranexamate HCl )
3. Cases affecting efficiency Is there any that help reduce it? Is it easy to spread without disturbing the performance?
thank you very much
