The novel sunscreen know-how goals to deal with client wants for prime UV safety in sizzling and humid climates whereas sustaining a light-weight, non-greasy really feel, and shine management.
This new method was detailed in a publication within the February 2025 situation of Beauty Science and introduced by means of a press assertion on March 10.
The core of the innovation lies in the usage of Polyionic Complicated Gel Particles (PGP) that are shaped by binding polymers with many constructive prices in an aqueous resolution that’s negatively charged.
These PGP kind the bottom of the sunscreen formulation, an oil-in-water (O/W) emulsion, and has been proven to carry out higher than O/W formulation with out PGP.
“It has been discovered that this formulation reveals greater UV absorption capability in comparison with current water-in-oil emulsion formulations that don’t use PGP with the identical quantity of UV filters. That is regarded as as a result of the powder is uniformly dispersed inside the three-dimensional construction of the PGP, permitting it to totally exert its impact,” mentioned the researchers.
Regardless of containing a major quantity of oil, the formulation claims to have a lightweight and refreshing texture.
In line with the agency it was well-received in consumer trials with 245 Asian girls aged 20 to 40.
The event of this know-how was pushed by the precise calls for of shoppers dwelling in Asia.
“Within the sizzling and humid areas of Asia, merchandise with a light-weight, non-sticky really feel, shine management results, and resistance to sweat and sebum are extremely desired. Whereas sustaining excessive UV safety, a sunscreen formulation that meets these client calls for was developed utilizing the brand new PGP know-how, created by R&I Japan.”
Self-repairing UV
In line with the analysis staff, the movie created by the PGP-based sunscreen exhibited self-repairing capabilities, making it resistant to break, comparable to friction.
This could give the formulation enhanced sturdiness and probably longer-lasting safety.
The identical movie was additionally discovered to have inherent micro-irregularities that scatter mild, resulting in a shine-prevention impact.
Apparently, researchers identified that this impact is enhanced upon contact with sweat and sebum.
“Moreover, the movie shaped by this formulation spontaneously creates high quality irregularities and displays a wonderful shine-preventing impact by scattering mild. When it comes into contact with sweat or sebum, this construction is emphasised, so we are able to anticipate the impact to be enhanced and sustained.”
Coming quickly
The PGP know-how will debut in Lancôme UV Professional Xtreem Protect SPF 50+ in April.
This week, Lancôme began to tease the launch on its social media channels.
This product has been billed because the model’s “first ever self-regenerating UV safety” and its “the largest UV safety innovation in a decade”.
The model claims that the product is waterproof, sweat-proof, rubbing-proof, and friction-proof, formulation that’s six-times extra resistant than typical UV formulation.
Moreover, the solar care formulation was examined on 49 Asian girls and 71% noticed an enchancment in spot color density in 12 weeks.
