  1. I won’t take the chance on Homosalate and how studies suggest it could be an endocrine disrupter. I need all the help I can get in that failing department. My favorites for the face are Elta MD clear and Beauty of Joesen (Korean) ❤️❤️🎉

  2. This was so legally blonde 👗lol Just FYI, she needs to get up-to-date with the science behind mineral sunscreen being purely a deflector vs chemical sunscreen. 😬

  3. The best sunscreen is one that you will wear and reapply! And don’t rely on sunscreen alone. Sunscreen is great but it’s not meant to be used in isolation. Sunscreen is just ONE part of sun protection. UPF clothing, hats, shade, umbrellas, and sunglasses are helpful too!

    The biggest thing is pick something that’s spf 30 or above because people tend to under-apply spf. You need a surprisingly thick layer to reach the SPF on the label. (So a higher spf helps you out. Even if you only apply 2/3 of what you need, you’ll still be at spf 20. )

    Don’t get too hung up on mineral vs chemical!

    Avobenzone gets a bad rap for being unstable + breaking down but it’s actually a really really good filter for UVA protection. It just needs to be stabilized with a couple of other filters. Regina demonstrated the Tha helioplex stabilized avobenzone was still providing 70% UVA protection even after five hours. (Obviously you should be reapplying if you’re outdoors but hey, sh*t happens sometimes. So it’s good to know.)

    (There are also some amazing UVA chemical filters outside of the US including Uvinil and Tinosorb. Amazon, yesstyle and French pharmacy websites are great places to order)

    Also
    We hear this “reflecting vs absorbing” thing a ton, but it’s more complex than that! Mineral sunscreens primarily absorb UV radiation just like chemical filters. (They do reflect 5-10% but they really do absorb the UV a lot like the chemical filters.)

    Mineral can be good for sensitive skin and it’s less likely to irritate your eyes. If you prefer mineral formulas, which is fine, be aware that they do have shortcomings. As good as some formulations are, zinc and titanium dioxide are still likely to leave a cast on darker skin. Tinted sunscreens are your friend if you have a lot of melanin and you want a mineral sunscreen. And the tinting ingredient (iron oxides) provides additional protection against visible light wavelengths that can exacerbate hyperpigmentation. But you may want to look up reviews of people with deep skin tones testing out tinted sunscreen, because some tinted sunscreens aren’t tinted enough and can leave you looking a weird beige color instead of actually blending seamlessly into your skin.

    If you’re a sunscreen nerd, enjoy vids by Lab Muffin Beauty, Dr. Dray, and Dr. Idriss.

    Oh, and to take off your sunscreen at the end of the day, you might try “double cleansing.” Step one: use a cleansing balm, oil, or micellar water to break up the sunscreen. Step two: wash it away with your regular cleanser.

    Enjoy the outdoors! Get some fresh air! Get some vitamin D and endorphins! Just protect your skin too!

    (And know that UV is present year round, even through clouds and car windows. So don’t think that sunscreen is just a summertime beach thing!)

  4. It's a myth that mineral sunscreen "is like a shield". It works mostly the same as chemical sunscreens by absorbing UV rays. The amount of UV rays that mineral sunscreen reflects is small.

    The other thing that people don't know is U.S. sunscreens are actually terrible at protecting against UVA rays. The FDA won't approve any of the new filters that are available now in other countries.

    The U.S. has zinc oxide and avobenzone for UVA protection. For zinc oxide, the UVA protection is usually pretty low (less than 20 UVA-PF), unless you apply it so thick that it's visible. For avobenzone, you have to make sure it is in high enough concentration and has stabilizing ingredients like octycrylene, or it breaks down and stops working.

    The U.S. doesn't have any standards to make sure that UVA protection is high. In the EU and Australia, the UVA protection has to be at least 30% of the SPF.

    If you have to buy U.S. sunscreen, Neutrogena and La Roche-Posay are most likely to have good UVA protection, because they are front runners in sunscreen science.

  5. Sunscreen is the truth!! I didn't know about the lip balm, cool!! I might have to check that out!! Thank You All for this Coverage!! May God Continue to Bless You All and Your Love Ones Abundantly With His Love In The Name Of JESUS CHRIST!! 🙏🏾🙌🏾✝️🌞🌱✌🏾🕊️
