This formulation is a sunscreen product containing a blend of chemical UV filters and various other cosmetic ingredients.

Active Sunscreen Ingredients

The primary active ingredients for sun protection are:

• Homosalate (15.0%): Provides UVB protection.
• Octisalate (5.0%): Provides UVB protection and helps dissolve other UV filters like Avobenzone.

As noted by the staff, due to the high percentage of sunscreen actives, it is advisable to use skin-nourishing ingredients at lower concentrations to prevent the formula from becoming too sticky or heavy.
