hello
If I use Phenylethyl Resorcinol , which should include a UV protectant such as ActiveProtec™ UV or BEMT ( Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) but with a penetration enhancer such as DMI, will those sunscreens penetrate the skin more easily? Is it dangerous?
or if put in an opaque bottle No UV protection is required.
thank you
