High performance sun protection that delivers more than SPF. Solar 50 is our broad spectrum SPF 50, made to protect, hydrate and visibly improve clarity and tone. It's lightweight, never greasy, leaves no white cast and works beautifully under makeup, which is exactly why it gets worn every single day, and daily wear is where the results live. Beyond the UVA and UVB defence, thermus thermophilus ferment, a marine derived antioxidant, helps protect against infrared and environmental stress. Panthenol hydrates and calms, glycolic acid supports clarity and smooth texture, and aloe vera with glycerin keeps skin comfortable all day. Apply liberally every morning as your final step, after Power AOX for extra antioxidant protection, and reapply every two hours in the sun. It's daytime only; at night choose Cream Repair, Cream Revive, Cream Drench or Cream Lift. Wear it for 60 days, and if your skin does not love it, every penny back.
