The novel sunscreen know-how goals to deal with shopper 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 subject of Beauty Science and introduced by way of a press assertion on March 10.
The core of the innovation lies in the usage of Polyionic Complicated Gel Particles (PGP) that are fashioned by binding polymers with many optimistic prices in an aqueous answer 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 exhibits 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 considered 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.
Based on the agency it was well-received in consumer trials with 245 Asian ladies aged 20 to 40.

“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 shopper calls for was developed utilizing the brand new PGP know-how, created by R&I Japan.”
Self-repairing UV
Based on the analysis workforce, the movie created by the PGP-based sunscreen exhibited self-repairing capabilities, making it resistant to wreck, corresponding to friction.
This might give the system enhanced sturdiness and doubtlessly longer-lasting safety.
The identical movie was additionally discovered to have inherent micro-irregularities that scatter gentle, resulting in a shine-prevention impact.
Apparently, researchers identified that this impact is enhanced upon contact with sweat and sebum.
“Moreover, the movie fashioned by this formulation spontaneously creates tremendous irregularities and reveals a wonderful shine-preventing impact by scattering gentle. When it comes into contact with sweat or sebum, this construction is emphasised, so we are able to count on the impact to be enhanced and sustained.”
