There is typically quite a bit of confusion and misunderstanding between the difference of sunscreen products and treatments that are formulated as sunblocks.
Although it may seem obvious, sunscreen's function is to "screen" the sun while sunblock actually "blocks" the sun.
In anti-aging skin care it is critical to prevent the sun from damaging the skin.
The Difference Between Sunscreen and Sunblock:
Sunscreen is defined as:
". . .a screen to protect against sun or a preparation applied to the skin to prevent sunburn (as by chemically absorbing ultraviolet radiation)."
Sunblock is defined as:
". . .a preparation applied to the skin to prevent sunburn (as by physically blocking out ultraviolet radiation)."
In other words, sunscreens are formulated to protect against UVA rays, which promote skin damage while sunblock products are formulated to stop the damage caused by UVB rays, the kind that cause a sunburn.
The main difference in sunscreen and sunblock lies is the way they protect the skin from UV rays:
it is critically important that whichever sun care product you chose that it protects against both the sun's UV (ultraviolet) rays on both the UVB and UVA spectrum.
UVB exposure is associated with sunburn, while UVA is a deeper penetrating form of radiation. UVA exposure is suspected to be linked to skin cancers, including melanoma.
Anthelios is a long-lasting OTC sunscreen with a new ingredient to the USA market, ecamsule, that provides protection from both sun damage and cancer-causing UV rays.
News sources report that Anthelios SX will play a very important role in offering additional protection against skin cancer and aging skin care issues caused by sun damage as it is thought that Anthelios SX may more effectively block UVA than current sunscreening products available in the U.S.
Remember to use your sunscreen or sunblock each and every morning and reapply as needed throughout the day!
Consider sunscreen and sunblock your greatest ally against aging skin!
