Derm-Level Age Defense Protocol
Derm-Level Age Defense Protocol
Defend by Day. Renew by Night.
Tull MD's Derm-Level Age Defense Protocol is a clinical-strength vitamin C + retinoid system engineered for visible, lasting age defense. This dermatologist-curated duo works in sync — protecting and brightening by day, renewing and resurfacing by night — to deliver smoother, more radiant, younger-looking skin.
C-E-FA™ Anti-Aging Serum (AM): A potent antioxidant serum powered by stabilized Vitamin C, Vitamin E, and Ferulic Acid. Shields skin from environmental aggressors, neutralizes free radicals, brightens uneven tone, and supports collagen synthesis for firmer-looking skin.
Revinoin™ Overnight Repair Serum 0.5% (PM): A medical-grade retinoid serum that accelerates cellular turnover overnight. Visibly reduces fine lines, wrinkles, and discoloration while refining skin texture and tone for a smoother, more even complexion by morning.
Together, this protocol delivers a complete 24-hour defense and renewal system — the clinical standard for comprehensive anti-aging care.

Powered by clinically advanced formulations
Medical-grade skincare is formulated with clinically proven ingredients at concentrations designed to deliver real, visible results. Unlike cosmetic products that work mainly on the surface, these formulations are engineered to penetrate deeper, target the root causes of skin concerns, and perform consistently. Every Tull MD product is developed with physician oversight and held to rigorous standards—because your skin deserves results, not promises.
Let customers speak for us
This has become an easy daily staple for me. The tint blends in naturally and does a great job evening out my complexion without looking like makeup or leaving that typical mineral sunscreen cast. I especially love the matte finish. It keeps shine under control throughout the day, but doesn’t make my skin feel tight, chalky, or overly dry.
It layers beautifully under makeup, although I often wear it alone for a polished, “my skin but better” look. The SPF 50 mineral protection gives me peace of mind for everyday sun exposure, and the formula feels comfortable enough that I actually look forward to applying it every morning. A great option for anyone who wants high-level sun protection with a flattering, non-greasy finish.
I really enjoy shopping with Tull MD. The products are excellent, the service is always personal, and I love knowing that my purchase also supports their work in skin cancer research, education, and prevention. It feels good to support a business that is doing something meaningful.
Really happy with this sunscreen. The tint blends in easily, it doesn’t feel heavy or greasy, and I love the matte finish. I’ve been reaching for it every day.
The selection of skincare and sunscreen products is perfect for my active lifestyle. My orders almost always ship the same day, and the handwritten note is such a thoughtful touch. That kind of personal service is hard to find anymore!
This cleanser leaves my skin feeling clean and refreshed without making it feel tight or dry. It’s gentle enough to use twice every day and does a great job removing sunscreen and makeup. I’ll definitely keep buying it!
My skin feels smoother, plumper, and much more hydrated since I started using this. It absorbs quickly, isn’t sticky, and layers perfectly under my makeup and sunscreen. Took care of my fine lines! Definitely a five-star product!
Shopping with Tull MD has been an exceptional experience from the very beginning. It started with a complimentary personalized consultation with Dr. Tull, who took the time to understand my skin, my concerns, and what I was hoping to achieve. That level of medical expertise and personal attention immediately set Tull MD apart.
I’ve since shopped with them both in person at some of the country’s most prestigious horse shows and online, and the service is consistently outstanding. Whether I’m ringside looking for the right sunscreen for a long day outdoors or ordering skincare from home, the recommendations always feel thoughtful, personal, and specific to my needs.
The products themselves are equally impressive. Tull MD has the most comprehensive collection of physician-dispensed, medical-grade skincare I’ve found, with formulas that address everything from daily sun protection and hydration to acne, aging, recovery, and overall skin health. You can tell there is real medical thought behind the collection rather than simply a group of products being sold together.
What I appreciate most is that Tull MD combines the expertise you would expect from a dermatologist with the personalized service of a luxury boutique. For anyone in the equestrian world who spends long days outdoors and wants to take better care of their skin, I can’t recommend Tull MD highly enough.
I’ve been using GF-RX consistently and can genuinely see a difference in my skin. The growth factor formula seems to give my skin a smoother, firmer, more refined appearance, especially around the areas where I was starting to notice fine lines and uneven texture. My skin looks plumper, more hydrated, and noticeably more luminous, and overall it just looks healthier and more youthful. I also love that it feels rich and restorative without being heavy or greasy. This is one of those products where I actually look in the mirror and notice that my skin looks better. GF-RX has absolutely earned a permanent place in my routine.
I love this cleanser. It is incredibly gentle on my skin, leaves it feeling thoroughly refreshed, and has a beautiful, light citrus scent. A little goes a long way. This has officially become a permanent staple in my daily skincare routine. I highly recommend it!
Once again, Tull dermatology products for the win! This serum smooths the skin, kills the acne and builds confidence.
Living an indoor/outdoor life, I don't have time to constantly apply sunscreen every time I'm in/out of the house or barn. Starting my day with Tull Tinted Matte Defense Mineral Sunscreen SPF 50 is a great base to my skincare routine and lasts all day. *A win!
Love the feeling of putting on this eye serum. It’s so cooling and relaxing. Doesn’t leave any residue and my eyes look well rested and refreshed!
After long days in the sun and elements, my skin really needed something restorative at night, and Revinoin serum has exceeded my expectations. My skin feels smoother, looks brighter, and has a more renewed, healthy glow by morning. It feels luxurious, absorbs beautifully, and has become an essential part of my evening routine.
Lovely, sheer coverage and wonderful sunscreen! What more can you ask for? I have sensitive skin and this was perfect. Can be used under foundation or as a light foundation on its own. Highly recommend!
It is a wonderful product. Can see the difference immediately in contour and less puffiness under the eyes! Highly recommended.
