Overview


The 40mm F1.4 DG HSM Art is Sigma’s first lens developed originally to live up to the sought-after angle of view and performance standard for a benchmark cine lens. This lens effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration. Designed for exceptional sharpness at maximum aperture, this lens excels at available light photography. With less than 1% distortion and near non-existent sagittal coma flare, this lens demonstrates consistent optical results featuring both 8K-compatible resolution and a beautiful bokeh. The Sigma 40mm F1.4 DG HSM Art is available for Sigma, Nikon, Canon and Sony E mount camera systems.

Leaves white cast, works okay under makeup.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
First time using this sunscreen. I have very sensitive skin and thought since my skin tolerates their cleansers and moisturizers surely it should tolerate the sunscreen. So far so good. It’s very calming on my skin (maybe because of the zinc), but it leaves a noticeable white cast especially if you have dark skin. I wear mine under makeup and have a separate sunscreen from another brand on days where I don’t want to wear makeup. The white cast actually acts as a blank base and helps my foundation to lay well. A tip I learned from makeup artists years ago. Sunscreens that leave a white cast cancels out your natural color and acts as a corrector, concealer and foundation to lay better and look more like skin. Think of it like painting on a blank canvas. The texture is not lotion like and is actually quite thick. make sure to moisturize well before apply this sunscreen. I’ll write an update if I notice any negative issues, but so far I’m content with it because of the purpose I'm using it for.

Safe for very sensitive skin
Style: SPF 50, Size: 3 Fl Oz (Pack of 1), Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
It is an excellent choice, especially if you have sensitive skin or want to avoid chemical filters. Minerals such as zinc oxide and titanium dioxide act by forming a barrier that reflects UV rays instead of absorbing them.

Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.

Great choice
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.

My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.
