A weightless daily sunscreen that protects, defends against aging, 
and disappears into every skin tone no white cast, no greasy 
finish. The one I tell every client they can't skip.

If you've ever avoided sunscreen because it felt heavy, greasy, or 
left a chalky cast  this is the one that changes your mind. Circadia 
Light Day is a lightweight, fast-absorbing broad-spectrum SPF 37 that 
protects against both UVA and UVB rays while going on completely 
clear on every skin tone.

What sets it apart is what's inside beyond the sun protection: 
award-winning Solastay® S1 keeps the formula stable and reduces the 
sensitivity some sunscreens cause, while advanced antioxidants 
(Lipochroman™ and Preventhelia™) and grape stem cell extract defend 
your skin against environmental damage and premature aging at the 
cellular level. It's gentle enough to use even after peels, waxing, 
and other treatments.

WHAT IT DOES:
- Broad-spectrum SPF 37 UVA/UVB protection
- Goes on clear — no white cast on any skin tone
- Lightweight, fast-absorbing, non-greasy finish
- Antioxidant defense against environmental aging
- Helps protect against blue light / HEV stress
- Gentle enough for after peels, microdermabrasion, and waxing

WHO IT'S FOR:
Every skin type, every day. Especially great if you've struggled to 
find a sunscreen that doesn't feel heavy or leave a cast — and 
essential if you're using acids, retinoate, or treating acne marks.

HOW TO USE:
Apply liberally to face, neck, and ears 15 minutes before sun 
exposure, as the last step of your morning routine. Reapply 
throughout the day with prolonged sun exposure. A nickel-sized amount 
(about 1/3 teaspoon) for the face is the right amount for full 
protection.

ESTHETICIAN TIP:
Daily SPF is the single most effective anti-aging step there is — and 
it's non-negotiable if you're using exfoliating acids or treating 
dark spots, since those make your skin more sun-sensitive. The reason 
I love this one is simple: it's light enough that you'll actually 
wear it every day. The best sunscreen is the one you don't skip.
