It’s the UV that is the issue not the heat. Unless climate change shifts the tilt of Earths axis, your likelihood or receiving the rays will be more or less the same per season.

Most products are specifically packaged for a given market. Especially with more regulated products, it's may be legal to import the product itself, but not in the packaging that is legal in other places. Plus there are language barriers, supply network differences, differences in store shelf standard sizes so bottles fit on shelves, etc. It likely will take time to design and produce the packaging, push the product to each stage of intermediate warehouses, and finally get it to stores.

That said and individual could import their own, but you'll have to pay for the shipping yourself and deal with any market differences in pricing and costs of currency conversion if your credit card doesn't do it for free.

The article even states they aren’t expected to hit shelves until the end of the year.

This paper isn't free at the link but you can read the abstract, partially quoted below:

Toxicopathological Effects of the Sunscreen UV Filter, Oxybenzone (Benzophenone-3), on Coral Planulae and Cultured Primary Cells and Its Environmental Contamination in Hawaii and the U.S. Virgin Islands

"We examined the effects of oxybenzone on the larval form (planula) of the coral Stylophora pistillata, as well as its toxicity in vitro to coral cells from this and six other coral species. Oxybenzone is a photo-toxicant; adverse effects are exacerbated in the light. Whether in darkness or light, oxybenzone transformed planulae from a motile state to a deformed, sessile condition. Planulae exhibited an increasing rate of coral bleaching in response to increasing concentrations of oxybenzone. Oxybenzone is a genotoxicant to corals, exhibiting a positive relationship between DNA-AP lesions and increasing oxybenzone concentrations. Oxybenzone is a skeletal endocrine disruptor; it induced ossification of the planula, encasing the entire planula in its own skeleton."

Improved uv protection and longevity are the major points, so youll age more gently long term and you wont have to strictly reapply every 2 hours - since im mostly in doors minus a 20m daily walk, i only apply once in the morning

But also the new sunscreens rub in and blend in better and dont feel as greasy so it not gross to put on and wear everyday

I dont wear makeup, so if the sunscreen is super shiny or pilly my face looks wierd, i dont like how i look, not so with the new filters

With my current sunscreen, its just part of the routine and its barely a thought for me - dosent smell bad, dosent feel bad, dosent make me feel sticky or tacky or greasy or shiny, i just put on 3 pumps (or finger lengths) to appropriatly protect my face, ears, and neck and its easy, and i use a cheaper american sunscreen on my arms to keep cost down

Hard to describe, but i tried a bunch of fda-approved sunscreens once i understood how damaging the sun is and how it affects aging and skin cancer and never found one that i really liked, so i imported some from abroad at the suggestion of a friend and finally found my sunscreen, and now i feel naked without it, wheras it was a chore like eating boiled brussle sprouts before

It doesn't feel disgusting.
