Sunscreens--Skin cancer/photoaging(girls listen closely)
Posted: Tue Sep 06, 2016 2:27 am
For 5 years guarding myself against the sun has been of utmost importance. For those concerned about wrinkling,sagging,cancer, melasma, hyperpigmentation, this is it. It will blow your mind
80% of photoaging is due to the sun.
Now what can we do about it? Recently a man made antioxidant(Tiron) was developed that actually stops the electrons from becoming excited during ROX oxidation redox processes that take place when UV rays are in contact with the skin. How effective? They say roughly near 100%. The damage takes place at the mitochondria where the rays penetrate the cellular walls and excite a key component in Iron take takes place during the intra cellular transprot mechanism. In essence it screws with our ability to generate energy for our cells, the cell starves and undergoes apoptosis, and cells are only capable to dividing so much. (think telomeres and the hayflick limit)
This antioxidant wont arrive in the nearby markets anytime soon.
Now what can we do currently?
I hate to say it but OUR FDA mandated sunscreens are crap. I'll begin by saying that Japan,EU and australia have tougher formulations. and less restrictions as far as chemical ingredients go. BASF and international agency strives to develop the very best ingredients and does emphasize excellent UV filters and state of the art ray deflector chemicals that serve to stabilize oxybenzone,octocrylene and avobenzone which do a great job but being unstable breakdown under the suns rays .
Sunscreens fall under the following categories:
1. chemical --Tinosorb a2b, tinosorb S,tinosorb M,Uvinul A plus, Uvinul T150, ecamsul(mexoryl), homosalyte, octocrylene,avobenzone
2.Physical --zinc oxide, titanium oxide(this encompasses zcote and micronized family) -- theoretical drawbacks will be explained
Physical sunscreens in theory are better, they are 100% broadspectrum and technically do the job right. The main drawback is they are incredibly difficult to formulate right and dont do well under the influence of moisture. Sweat will easily wipe them off and on top of that The reason they are hard to formulate is because despite being micronized, no matter how hard you try they still allow a significant uv rays to filter through. This is because these metals are porous. You would think making them smaller would serve to deter this issue but there are are great concerns that making them nano sized will become absorbed through the skin. The danger comes into full motion when the rays excite these nano particles and cause electrons to spin. Yes that right, even more free radicals than without use of any sunscreen.
Chemical sunscreens have a degree of toxicity and free radical damage provided only when chemical bonds break down and molecules becomes unstable.
They are incredibly good at reflecting , absorbing and filtering UV rays, some dont even have that awlful white cast you get when using zinc oxide.
Heres the down side. FDA regulations are incredibly outdated. Recently in the United States. Only a selective few outlets are permitted to use loreals mexoryl (ecamsule) photostabalizer and UVA filter. That was in 2013. This molecule has been in full use in european nations since 1991.
Today BASF's latest line are the Uvinuls and tinosorbs. They are incredbly impressive. Not only do they lengthen the half life of Avobenzone and other UVA 1 components but they are impressive against sweat and moisture. Have an even greater critical wavelength against the sun higher than 380nm.(close to blue light or HEV light.
And filter out UVA / UVB rays extremely well. --some european sunscreens even filter out infrared A rays
Imortant to know spf only guard against UVB rays, it indicates nothing about UVA.
A spf of 30 filters out UVB rays 95-96% efficiently.
A spf of 50 96-97% efficently
spf 60 97-98%
spf 70 98.1% etc....(you get where im going with this)
Going higher up the spf is meaningless. Check the formulations at the back of product. AIM for those newer ingredients. Ecamsule is good
Buying european formulated sunscreens with uvinul and tinosorb family are way way better
And wear sunguard UPF 50 + clothing.That also includes a wide brim hat like those military camo hats There are are pants and long sleeve shirts meant to guard against the sun. Again UPF 50+
wear blue blockers or raybans and dont be afraid to put sunscreen near eyes. Theyre are some good foreign brands such as heliocare and daylong(swiss) that are great for this. (Yay against crows feet.)
APPLY SUNSCREEN EVERY 2 HOURS MINIMUM (or when it starts rubbing off)
UVA and UVB rays pass through clouds and during winter its worse because they reflect off of snow(yikes!!!!!!!!!!)
You cant feel UVA rays, UVB rays cause the reddening and burning
I get ridiculed for being allergic to the sun. I'm a vampire.
I bestow this knowledge to all of you so you guys and gals are able to defend against the sun
NB = forgot to mention Japan uses the Pa++++ system and europe uses either the 5 star or PPf system for seal of approval against UVA 1 and UVA 2 wavelengths
Also get congress to update those formulations. Its so sad to see you guys in USA behind. Get with the times!!!!!!!!!
