Beauty Tips For Body Care
As much as I love the science and chemistry behind skincare, I know that I still have plenty to learn.I use Klair's spf daily and love it, no whitecast, no irritation, and it's slightly moisturizing too.I know that The Beet Shield is pretty much on par with it, but they give you less in the tube and I didn't think there was enough of a difference between the two to decide to try out the beet shield instead, knowing that klair's already works fantastically for me. And they have the same SPF ratings.However I did come across this comment on makeupalley:EDIT: Had to remove 2 lippies because this sunscreen does not protect against UVA1 rays. It protects against UVA2 and UVB rays (Ethylhexyl Triazone (blocks UVB) and Uvinul A Plus) only.The only actives that protect against UVA1 are Zinc Oxide, Tinosorb S and Tinosorb M.Krave Beauty's Beet Shield is a better option for a broad spectrum sunscreen that doesn't have white cast and isn't irritating.Can anyone confirm or deny this? Can't find any articles comparing the two specifically, and I'm not sure if this was made when Klair's was using an old formulation or something (comment was made 2 years ago according to the website).Does the beet shield actually offer more protection? Their ingredient list doesn't contain zinc oxide, tinosorb s, or tinosorb m either, so I don't understand what the commenter is saying.Any help would be appreciated!edit: I found an article that I can't find the link to anymore (closed the tab on private browsing :( ) but it was describing how chemical sunscreens don't actually block UVA that well. I'm actually seriously considering switching to a 20%+ zinc oxide mineral sunscreen now.edit 2: found the article. it reads,The filters (chemical and physical) that are useful against the penetration of UVA1 are avobenzone, Tinosorb (S and M), Mexoryl (SX), Uvinul A Plus, and zinc oxide...Zinc oxide differs from the rest in that its a physical sunblock. Physical sunblocks are advantageous in some ways in that they do not cause photoallergic reactions; they provide stronger coverage that may be harder to wash off, yet cuts down the need for constant re-application every few hours; and they block UV absorbance immediately, unlike chemical sunscreens that are not effective until 15–20 minutes after contact with the skin. Zinc oxide does not really have a peak absorbance value as it is a uniform UV protectant, protecting against wavelengths from the UVB spectrum to the UVA spectrum. At crucial high wavelengths (385–400 nm) — those that induce significant collaganese (i.e., collagen breakdown) induction — zinc oxide offers greater protection than organic filter Mexoryl SX. (7)edit 3:Zinc oxide is a safe and effective ingredient in photoprotective products. It is photostable, nonphotoreactive,[19] and nonphotocatalytic.[12] It has little potential for irritation or sensitization. Smaller, micronized zinc oxide is considered as a broad-spectrum UV protectant. Although not as efficient in the UVB range as titanium dioxide, this inorganic UV filter covers predominately the UVA spectra, with protection into UVA1. Zinc oxide is also considered inferior as a UV filter to the organic sunscreens.[12]from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482794/edit 4, from the klair's website itself:It is impossible with current technology to perfectly block all UV wavelengths with just sun cream alone. And Klairs Soft Airy UV Essence is not a completely perfect product. But with an SPF50+ PA++++ rating, Klairs Soft Airy UV Essence has proven broad spectrum UV blocking abilities, including UVA1But it doesn't say how much uva1 rays it blocks? so confusededit 5: so I did some more research and read that Uvinul A Plus (one of the two UV filters that Klairs uses) does cover uva1 protection, and "is clearly similar to avobenzone in terms of absorptive capabilities, but due to superior photostability, it is known to be its successor." But then I did find a reddit post of someone asking klairs/wishtrend directly if it covered uva1 and they said it didn't? But then there's a labmuffin article that says it does? So much conflicting information here.
