Smooth Mineral Defense Fluid Sunscreen System

Smooth Mineral Defense Fluid Sunscreen System

Your Complete Sheer Sun Defense System

Tull MD's Smooth Mineral Defense Fluid Sunscreen System is a complete, layered sun protection system designed for all-day defense — from morning application to midday touch-ups. This dermatologist-curated trio combines three medical-grade mineral sunscreens, each engineered for a specific role in your daily UV protection routine.

Smooth Mineral Defense Fluid SPF 50: A sheer, lightweight mineral sun serum powered by 25% Micronized Zinc Oxide and a potent antioxidant complex. Provides broad-spectrum UVA/UVB protection while visibly brightening and hydrating skin. The perfect AM base — wear alone or under makeup.

Antioxidant Sunscreen SPF 40: A fast-absorbing, water-resistant SPF 40 with vitamins A, C, E, and green tea to neutralize free radicals and shield against sun damage. No white cast, 80-minute water resistance — ideal for active days.

Brush-On Mineral Powder Sunscreen SPF 30: A 100% mineral powder SPF in a portable brush applicator. Enriched with ceramides, hyaluronic acid, and antioxidants — perfect for seamless midday reapplication over makeup, on the go.

Together, this trio delivers a complete morning-to-evening sun defense protocol — broad-spectrum protection, antioxidant support, and effortless reapplication in one curated bundle.

Brilliant! The perfect addition to my ring bag.

Absolutely love this brush on powder sunscreen! It’s the perfect addition to my ring bag. It's lightweight, easy to apply, and ideal for touch-ups between classes. It’s going to be a lifesaver in the Florida sun!

Convenient and effective!

I bought this product for my daughter to keep in her trunk at horse competitions. It has been convenient and effective -- especially on hot sweaty days! Thank you!

Thank you, Erin! We're so glad you're both pleased, and we're incredibly appreciative of your support! Hope to see you again soon.

It is very hard to apply the powder. I won’t buy again.

Hi, Aleksandra. We're so sorry you're having issues applying the powder. Simply turn the bottom clockwise one click to open the powder chamber, then tap upside down to allow the powder to enter the brush. Remove the cap, slide the brush shield down and apply. If you'd like to hop on a video call, we're happy to show you live how easy and convenient our Brush-On Mineral Powder Sunscreen can be, especially for day-time touch-ups.

Best in Class

I used the Peter Thomas Roth product for years until they discontinued it, and I’ve been looking for a replacement since. I’ve tried 3 or 4 different brands and none came close to matching the original. I recently bought the Tull Brush on Mineral Powder and found it to be even better than the Peter Thomas Roth product.
It brushes on effortlessly and the powder is light enough not to look caked on. It’s slightly tinted which is a big plus as you don’t want a powdery look on your face.
I even received a hand written note, very impressed by that btw, thanking me. Also included was a free sampling of 4 facial products. This is truly a great buy.

Michael, thank you so much for your amazing review and for choosing our ProSport Brush-On Mineral Powder Sunscreen. We are thrilled to hear that it exceeded your expectations and even surpassed your previous favorite product. We take pride in providing a high-quality, effortless, and natural-looking sunscreen for our customers. We are also happy that you appreciated our hand-written note and free samples. Your satisfaction is our top priority and we appreciate your support. Thank you again, and we hope to continue providing you with great products and excellent customer service.
