Dermatologist Developed
Medical-grade SPF, developed by a dermatologist.
"Medical grade" gets thrown around a lot in skincare. Here's what it means to us: sunscreen formulated by a board-certified dermatologist, built on medical-grade ingredients at clinically meaningful concentrations — not a marketing label bolted onto a basic formula. JACKET is the SPF Dr. Thomas Balshi developed for his own patients, his family, and himself.
What makes an SPF "medical grade"?
Developed under medical expertise
JACKET wasn't licensed from a contract catalog. Every formula was developed by Dr. Thomas Balshi, a dermatologist and cosmetic surgeon practicing in South Florida for more than 25 years — where sun exposure is a daily, year-round reality for his patients.
Medical-grade ingredients
Zinc oxide for true broad-spectrum UVA/UVB defense, paired with select super antioxidants and premium medical-grade ingredients chosen to support skin while it's protected — hydrating, repairing the look of existing damage, and defending against environmental stressors.
Performance you can measure
SPF 50+ broad spectrum. Water and sweat resistant (80 minutes). Reef safe. Blue-light conscious. And formulated to feel like skincare, not sunscreen — because the best SPF is the one you'll actually wear every day.
The medical-grade lineup.

Medical-grade SPF, answered.
What is medical-grade sunscreen?
Medical-grade sunscreen generally refers to SPF products developed with clinical oversight and formulated with higher-quality, tested ingredients at effective concentrations — the kind of products historically sold through dermatology practices rather than drugstore shelves.
Is JACKET a medical-grade SPF?
JACKET was developed by Dr. Thomas Balshi, a dermatologist and cosmetic surgeon with 25+ years in practice, using zinc oxide, super antioxidants, and premium medical-grade ingredients. It's the sunscreen he developed for his own patients — and wears every day.
Do I need a prescription for medical-grade SPF?
No. Sunscreens are regulated as over-the-counter products in the US. "Medical grade" refers to how a formula is developed and what goes into it — not to prescription status.
Is mineral or chemical sunscreen better?
Mineral filters like zinc oxide sit on the skin and physically deflect UV, offer immediate broad-spectrum protection, and are generally gentler on sensitive skin — which is why JACKET's formulas are built around zinc oxide plus skin-supporting antioxidants.
What SPF level do dermatologists recommend?
Most dermatologists recommend broad-spectrum SPF 30 or higher for daily wear, and SPF 50+ for extended time outdoors. JACKET's hero formula is SPF 50+, water resistant for 80 minutes, and comfortable enough to reapply the way you're actually supposed to.
