Product Details

Physical Fusion UV Defense SPF 50 is a weightless fluid that combines 100% mineral filters with translucent color spheres for effective broad spectrum UVA/UVB protection and an even, radiant finish. This high protection zinc oxide sunscreen also contains artemia salina, a plankton extract known to increase skin’s resistance to UV- and heat-induced stress.

  • Sheer, tinted sunscreen adapts to most skin tones without a white cast
  • Water resistant for up to 40 minutes
  • Boosts radiance for a more even, luminous complexion
  • Helps boost skin’s natural defenses to environmental stress
  • Paraben-free and fragrance-free; non-comedogenic
  • Ideal for all skin types, even very sensitive skin

How To Use

Shake well before use. Apply sunscreen liberally to the face, neck, and chest 15 minutes before sun exposure and before applying makeup. Reapply sunscreen after 40 minutes of swimming, sweating, immediately after towel drying, and at least every two hours. For children under six months of age, consult a physician before use.

Sun Protection Measures: Spending time in the sun increases your risk of skin cancer and early skin aging. To decrease this risk, regularly use a sunscreen with a Broad-Spectrum SPF value of 15 or higher and other sun protection measures including:
- Limit time in the sun, from 10 am - 2 pm
- Wear long-sleeved shirts, pants, hats, and sunglasses
- For children under six months of age, consult a physician before use

  • Science & Proof

  • Science

    This breathable, tinted sunscreen is formulated with transparent titanium oxide and zinc oxide (Z-Cote®), the only mineral UV filter shown to protect against the full UVA/UVB spectrum along with translucent color spheres and artemia salina to impart powerful UV protection with a natural radiance. A “shake then apply” dispersal technology helps ensure even distribution of sunscreen ingredients.

Key Ingredients

  • 5% Zinc oxide (Z-Cote®)
  • 6% Titanium dioxide
  • Artemia salina
  • Translucent color spheres

This microfine zinc oxide is a mineral filter that reflects sun rays to provide broad spectrum protection against UVA and UVB rays. The particle size and distribution characteristics spread evenly and provide a non-whitening effect on skin.

Physician Insight

Physician image

I love Physical Fusion because it is so easy to apply and does not clog up the skin or feel and look too heavy. The tint also gives it a nice smoothing effect on the skin. It is so easy to apply, and so effective in protecting the skin from sun damage, that I also use it daily on my three children.

Rated 2 out of 5 by from Too runny While the product does provide sun protection and evens my skin tone as promised, I just hate the consistency. It's way too runny and application is a nightmare. It also feels 'sandy' as I spread it across my face, almost like a micro-exfoliator. Not sure what that's about. Love Skinceuticals, but I will not be buying this one again.

Rated 2 out of 5 by from Very Drying I bought this as a replacement for Ultimate UV defence and it's very disappointing. I need a daily dog moisturizer to wear with my C&E Ferulic serum and under make up. This is just awful. It flakes off, and settles into pores. Bring back Ultimate UV defence. Please let know how to return this product

Rated 2 out of 5 by from Super Watery I believe this product will protect my skin from the sun, but it comes out like water and is messy. You waste product trying not to spill it everywhere.

Rated 5 out of 5 by from I love this sunscreen This is a great sunscreen, and the fact that it’s tinted is an awesome addition in the summer or before going to the gym when I don’t want to wear heavy makeup. It has a thin texture and low viscosity so it’s easy to spread on and being from skinceuticals I feel confident that it’s protecting my skin. I use it in the morning after applying my skincare and then I use my Lumasol spray to reapply sunscreen throughout the day.

Rated 3 out of 5 by from Review of tinted sunscreen I purchased this about a month ago looking for a tinted sunscreen for the face that would also add a glow to my complexion. I do like this product however, it is more watery than I expected. I had used another product by Dermstore (now discontinued) that was thicker and creamier and I prefer that consistency. I would likely purchase this product again if I can not find something I like better.

Rated 3 out of 5 by from This sunscreen feels good on and absorbs well into your skin unlike a lot of sunscreens for your face which leave a white chalky look. This has a slight tint which the company claims will work on any skin color - I’m not sure about that but it works well with my fair skin. You can even use it under foundation. The only problem I have with this product is it tends to run into my eyes when it’s hot out. I think I’ll probably use it more in the Spring and Fall and stick with Dermalogica in the summer.

Rated 5 out of 5 by from Zinc oxide mineral sun screen I just started using the physical defense 50 sunscreen. I have sensitive skin, and I need a recommendation as to what to use to remove the sunscreen. My Dermatologist tells me to wash my face with cephaphil .......I wash a few times ...still some on. I have Roseaca so no you have a product you recommend?

Rated 5 out of 5 by from Incredible! I am a fair skinned redhead and constantly on the hunt for the best mineral sunscreen. I gave this a try after seeing a friend use it who is also fair and it is love!! It’s very lightweight and silky and blends very well. I was very concerned about the tint at first because many still show up on my skin or oxidize orange and no one wants to look like a Cheeto puff! I have tried nearly all high end and most drugstore mineral sunscreens and so far this beats them all.

Rated 5 out of 5 by from Perfect 2-in-1 sunscreen & skin tint I've been looking for my holy grail sunscreen for a very long time; I am a fan of physical sunscreens as they are better for the environment and my body but many of them can be chalky or unpleasant on the skin, especially for all-day wear. This sunscreen feels very nice on the skin and the tint provides nice everyday coverage for my light-medium skin. I hope they never discontinue this wonderful product!

Rated 5 out of 5 by from LOVE!! This was the first Skinceuticals product I bought and I'm so happy with my purchase! I'll definitely be trying out more of their products. I've been using the sunblock for a week now and there hasn't been a single breakout for me which is amazing as other sunblocks I've tried ended up in breakouts. It has a nice matte finish, doesn't make my skin feel greasy and feels lightweight on the skin.

Rated 5 out of 5 by from My favorite sunscreen ever After reading some rave reviews of this product, I decided to try it, and am I ever glad I did. It is so light and comfortable to wear, invisible, and a high SPF. I will never buy any other kind of sunscreen again. Oh, and I also love that it is ocean safe.

Rated 1 out of 5 by from Bring back ULTIMATE UV DEFENSE SPF 30 So sad...bought this on customer service recommendation to replace ULTIMATE UV DEFENSE 30 and it's not even close. It's a thinner formulation and after short time white rolls of product show up on skin....same thing happened to my husband. Not sure why skincueticals would get rid of a best seller? Please please please bring ULTIMATE UV DEFENSE 30 back!!

Rated 3 out of 5 by from Love product, problem with service & expiration Bought this product online- have used it several years. However- the bottle that I received expires in 4 months. I expected to receive a product that had at least a year of use. I called and the rep said there was nothing Skinceuticals could do. Disappointed with customer service. I have been a loyal client for 7-8 years. I buy product online and from my esthetician. Never have I had this issue.

Rated 5 out of 5 by from My Fave! I have been using this lightweight, nongreasy, easy-to-apply, matte finish, and delicately tinted sunscreen for years and I won't use anything else. In the past, I suffered from rosacea and I continue to have skin sensitivity issues but this sunscreen works without causing any issues. My husband has started to borrow it as well. It even lasts all day during mountain biking, boating and other outdoorsy activities (although I'm sure the published recommendations require you to re-apply). I am never that organized but neither do I burn so it's a winner with me. LOVE IT!!!

Rated 1 out of 5 by from gritty structure, not smooth I bought this and liked that it has color in it. I do have rosacea on my cheeks and need to use sunscreen all the time and I thought tinted color would also help me not to use a lot of foundation. I am using this for more than 3 weeks and I ended up having more redness on my cheeks I think due to sandy structure. It is very fluid by the way, so it is difficult to manage the amount I use each time.The bottle tip is very narrow, so it is difficult to put the excess amount back.

Rated 5 out of 5 by from Fantastic Product I Started using this wonderful product about eight years ago and then my dermatologist office stopped selling it I was very upset they wanted me to use another brand name so I tried it and I wasn’t really happy with it this product I could go to the beach and hang out in my face would never get rid I’ve never felt dry it was the most wonderful product and I feel like I never had to wear a full foundation I’m glad I found this website and I’m following up with starting my regimen again with this outstanding product

Rated 5 out of 5 by from Amazing LOVE THIS I just started using this, my dermatologist recommended the product's I needed, I decided to call the company instead of buying these products from him. I read all the reviews, then called. I got VERY LUCKY, The lady I got to talk to was very knowledgeable about these products. She explained exactly how to use all of them. Is this somewhat as reviews say, running, Not really, do you want it thick as peanut butter? I'd rather it soak into my skin, which it does, very easily. Not sit on top. It's a beautiful UV Defense protection. It's not grainy at all. Shake it up like your suppose to. Follow your instructions. Easy peasy. Unless they make a better one, I'll use this from now on, every day to continue to protect my skin. I Love that it has no smell, overall IT'S A VERY BEAUTIFUL PRODUCT, I'D NEVER KNOW IT'S A DEFENSE UV SPF PROTECTIVE PRODUCT. FEELS LIKE SILK ON MY SKIN. I HIGHLY RECOMMEND YOU CALL AND DISCUSS ANY CONCERNS WITH THESE PROFESSIONALS BEFORE WRITING A BAD REVIEW, CHANCES ARE, YOU DIDN'T USE IT RIGHT. KEEPIN IT 100 THIS COMPANY SHOWS RESULTS IMMEDIATELY!!!!

Rated 5 out of 5 by from I have the MOST sensitive skin. Every sunscreen has either broken me out or given me an allergic reaction. This is the only sun care I can use! I have super sensitive, super dry skin, but would recommend to anyone!

Rated 1 out of 5 by from This sunscreen is incredibly disappointing. To be honest though, if it had been anything less than amazing with the price point for the bottle size I would have been disappointed. It’s incredibly liquidy and a bit hard to apply, plus I’m definitely on the pale side and it makes me look like I’m wearing the wrong color foundation. It’s very matte and it takes a solid minute to dry down correctly. Also not a fan of the smell
Date published: 2020-03-08
Rated 5 out of 5 by from This is my go-to daily SPF. I love that this is a mineral sunscreen that isn’t thick and doesn’t leave a heavy film on my skin. The skin tint (for pale skin tones) is great and prevents me from getting a white cast. I like that this is a more liquid product rather then a cream—this makes its easy to spread and blend into the skin. This sunscreen has one of the highest amounts of physical sunscreen I could find (I don’t use chemical sunscreens). It does leave a bit of a sheen/glow on the skin, but it’s nothing that feels heavy and oily—I don’t mind the sheen at all. Usually the sheen wears down after about 15 minutes. Overall, I love this sunscreen and will continue using it.

Rated 4 out of 5 by from Good It’s nice and something I fail to see grittiness as some reviews suggest would have loved a little pinkish tone
Date published: 2020-03-05
Rated 1 out of 5 by from Not for dry skin. Leaves visible film on face and picks up flakes, making them more visible. So, definitely don't use if you are using Retin-A. Even after using 10% glycolic the night before, it still has this flaky effect. Also, they say it's for all skin types. As a pale white person, I see flecks on my lips (which are a bit dark) if it so much as touches them. For this reason, I am seriously doubtful any person of color could use this at all.

Rated 5 out of 5 by from THE BEST! This is the only sunscreen that does not clog my pores. I started using it 3 years ago when my aesthetician recommended it. It is the best! I love the consistency. It smooths over the face so well. After seeing how great this product is, I gradually switched all my products to skinceuticals. I just went to the Caribbean a few weeks ago and my aesthetician was out of this product. So unfortunately I had to buy another high end sunscreen. I returned with my face completely broken out. Never again. I will make sure I have plenty of this product before I leave on my next trip.
