Sunny days ahead…. sunscreen a
must!
A search for patents using the
single search word “sunscreen” returned a whopping 4922 patents, a number commensurate
with all the warnings about the damaging effects of UV rays on skin and hair.
US8652449 titled Sunscreen compositions having synergistic combination of UV filters is a l’Oréal
patented sunscreen. The invention consists in reducing the overall amount of UV
filters while retaining high UV filtering capacity. This is achieved in the
discovery of a combination of UV filters that function synergistically to
filter UV rays. And, the main advantages
of having several different UV filtering agents that work synergistically is
that it enables to reduce the overall amount of UV filtering agents, which are usually
sticky and thick, while still maintaining a high Sun Protection Factor (SPF). So
L’Oréal’s new and advanced sunscreens are both lighter and more effective (with
a higher SFP).
Below you will find the abstract
for US8652449 titled Sunscreen compositions having synergistic combination of UV filters and an image of L’OREAL’s advanced sunscreen.

Abstract US8652449: The disclosure relates to sunscreen compositions having a synergistic combination of ultraviolet light (UV) filtering agents that provide a high sun protection factor (SPF). Compositions according to the disclosure have high SPF values without requiring high overall amounts of UV filtering agents. Furthermore, the disclosure relates to methods of using the described compositions for protecting keratinous substances such as skin and hair from UV radiation.
Now, enjoy the warmth of the sun
and stay protected!
