WHAT ARE THE BENEFITS OF SULISOBENZONE?

Sulisobenzone provides protection from ultraviolet-A2 and ultraviolet-B light. However, it is rarely used in products without oxybenzone since it is superior when in combination with oxybenzone.

WHAT IS SULISOBENZONE?

Sulisobenzone (i.e., benzophenone-4) is an FDA-approved organic ultraviolet-A2 (UV-A2) and ultraviolet-B (UV-B) light filter.

IS SULISOBENZONE SAFE FOR ALL SKIN TYPES AND TONES?

In vivo studies have shown that sulisobenzone is not associated with irritation. However, there are other studies that report its allergenic or irritation potential.

CONTRAINDICATIONS

There are no absolute contraindications for using products with sulisobenzone, but those with benzophenone allergies or reactions should avoid using products containing sulisobenzone. Sulisobenzone is thought to have immunosuppressive action, so it should be used with caution in patients who may be immunocompromised.
