Even though I’m a fan of physical sunscreens, I’mÂ nowÂ keen to tryÂ outÂ the chemical sunscreens under VichyÂ Capital Soleil and La Roche-Posay Anthelios because these featureÂ Mexoryl XL and Mexoryl SX which areÂ said to beÂ the most potentÂ photostable anti-aging sun filters for UVA and UVB rays.Â
HereÂ is a summary ofÂ information I have uncovered regarding these twoÂ potent sunscreen chemicals:
Offers complete protection against both UVB and UVA rays
It should be noted that most sunscreens available right now offer only partial protection because they only protect against UVB rays.Â Â But Mexoryl, whichÂ was developed by scientists at L’Oreal,Â is said to beÂ virtually impervious to sun exposure becauseÂ it is the only chemical thatÂ can block UVA rays which are responsible for our wrinkles, sun damage and certain skin cancers.Â In fact,Â it has been reported that when both Mexoryl XL and Mexoryl SX molecules are combined, they provide complete protection against both UVB and UVA rays.
ProvidesÂ optimum protection all day long
MexorylÂ is photostable andÂ this meansÂ you can wear it all day longÂ without the need to reapply and yet receiveÂ long lasting, effective protectionÂ asÂ it does not degrade in sunlight.Â
Works wellÂ with mineral makeup formula
The two Mexoryl molecules are able to work synergistically with each other and with other sunscreen filters including avobenzone (Parsol 1789), titanium oxide and zinc oxide to provide full spectrumÂ protection against both UVA and UVB rays.Â So unlike what I’ve discussed in my earlier entry regarding theÂ incompatibility of non-micronized mineral makeupÂ with an avobenzone containing chemical sunscreen, you should beÂ able toÂ wearÂ Mexoryl chemical sunscreen withÂ yourÂ mineral makeup, unless the formula comes with avobenzone as well.
Poses no health risks
Studies have shown thatÂ less than 0.1% of a Mexoryl application is absorbed by the body and this minimal absorption means that it is very safe to use.Â Â In addition, Mexoryl SX is water soluble, which meansÂ any that is absorbed is likely to be rinsed out quickly.Â Moreover, Mexoryl formulated sunscreens have passed various safety tests and have been approved for usageÂ inÂ Europe for over a decade now.
Provides water resistance
Mexoryl XL is oil soluble andÂ formulations containing Mexoryl XL are well suited for outdoor activeÂ usage on extended periods.Â Mexoryl SX on the other hand is water soluble and is recommended for daily wear.
Choices of Mexoryl sunscreens
Besides VichyÂ Capital Soleil and La Roche-Posay Anthelios, I understand that other sunscreens withÂ MexorylÂ include Lancome Sunblock UV Expert 20 with Mexoryl, Loreal Revitalift UV with Mexoryl SX and Kiehl’s UV Protective Suncare Sunscreen Cream For Face & Body.Â
I’ll probably like to try one or two of these for outdoor application first and see how they perform.Â If I like them enough, I may then start to use them on a more frequent basis.Â And hopefully, I’ll be able to post up some positive reviews too.
