The sunscreen formula is
Bisoctrizole 8%
Hyaluronic Acid Base Gel 92%
Another formula is
Tris-Biphenyl Triazine (Nano) 10%
Bisoctrizole 8%
Hyaluronic Acid Base Gel 82%
Can this formula work? And if so, what is the SPF?
The team can help with advice (I want a sunscreen formula that doesn't contain oil).
