FAQ
AC-SAP questions
Does SAP replace sunscreen filters?
No. It is an antioxidant ingredient, not a replacement for UV filters or finished-product SPF testing.
Is Sodium Ascorbyl Phosphate the same ingredient as Ascorbyl Palmitate?
They are different vitamin C derivatives. SAP uses a water-phase formulation route; Ascorbyl Palmitate is oil-soluble.
