Harken Derm has a concentrated formula and a small amount is enough to provide excellent protection. It has a consistency that will prevent running or dropping on surfaces to leave them or your hands slippery and oily.

Rub one or two pea-sized drops in between your fingers then transfer the sunscreen to exposed areas on your face and neck. Use circular movements to distribute it evenly making sure that no areas are skipped, and no streaks left behind.

Once it dries, Harken Derm will not run and will stay on your skin in the toughest conditions. Because mineral filters do not break down and reflect, scatter and absorb UV rays as long as they are on the surface of your skin, Harken Derm will protect you unless it is removed from your skin. It may appear somewhat opaque during application (which helps you to see which areas your skipped) or under the water but will blend with your skin again once it dries. It can be used under make-up due its primer-like hydrating properties. Reapply, if you spend a lot of time under the water or towel your skin frequently during the day.

FDA recommends reapplication of sunscreens every two hours. Harken Derm may leave a white residue on your darker clothes or diving goggles, which can be easily removed with gentle soap and water. It will not stain your clothes or fibreglass surfaces yellow like most chemical UV filters do.

Due to it’s quick-drying, non-oily feature, it will allow a perfect seal with your swimming or diving goggles. Because of its special film-forming long lasting formula, you may need to need to rub your face more rigorously to remove Harken Derm at the end of your day.

Apply Harken Derm Daily Skin Repair Lotion right after to hydrate and soothe your skin and help overnight repair and recovery. Carefully curated botanical ingredients safe to use in sunscreens and release their power gently.

Dr.Melanie Clark


As a dermatologist who specailzes in the treatment of skin cancer, I am picky about sunscreens. I prefer mineral-based physical blockers, but often find them to be thick, sticky, and difficult to apply. Harken Derm is the first sunscreen I have found that has all of the sun-protective benefits of a mineral sunscreen but goes on smoothly and easily. Not only does it feel wonderful on the skin, but it lasts hours and sweat and water exposure. I highly recommend Harken Derm to my family and my patients.

Brett Everson

I wear this product when I'm working outside and on the golf course, just a little bit goes a long way and continues working through the sweat. Doesn't have an oily or greasy feeling like most sunscreens, highly recommended.

Laura Nowlin

Great for the kids, too! This is the best mineral sunscreen I’ve used on me and my 4-and 8 year old. Goes on smooth and lasts forever. Forget the drug store stuff...this is the best!

Derek Doudna

The best sunscreen I’ve used to date. Great coverage and protection and lasts all day, giving top notch performance. Created by professionals with a proven track record.
