It is greasy like isopropyl mainly because it is.

Irrelevant. SPF 50+ with 4 star UVA is exceptionally high UVA protection. The stars are not a direct UVA protection rating, it is simply telling you how to calculate the percentage of the SPF rating that also applies to UVA. 4 stars means 90% of the SPF rating for UVB is also achieved for UVA, which means somewhere around 40-50 for UVA (actual calculation is impossible as it uses a ridiculous logarithmic scale and is technically the abosorbtion ratio...).

To further complicate it, the stars don't properly measure UVA. Only UVA2 really. The best sun cream right now is La Roche-Posay Uvmune 400, which has no stars listed on the bottle of almost all of them except one that shows 4. Yet it is vastly better for UVA protection than every other product as it uses a new Uvmune 400 filter which fully covers the UVA1 spectrum which 98% of sun creams don't do.

P20 Kids uses Triasorb M which also covers 380-400mm however not quite as well as Uvmune, still better than almost every other option.

Finally Avene uses TriAsorB which too blocks 400mm, however the actual quantity of normal UVA2 protection (the "SPF") is not known as they have refused to say and therefore I wouldn't trust them simply because it might cover the full range but ultimately not actually have a very high traditional UVA rating, which is still important.

The reason why it is known that La Roche-Posay Uvmune 400 has high traditional UVA rating even though they don't list any stars is because they have publicly released their PPD values, which would be between 3-5 stars SPF50+ depending on the product for traditional UVA protection so with the UVA1 protection from the Uvmune 400 filter, it means it is easily the strongest of the lot as Uvmune 400 is better than Triasorb M in P20 Kids.

All of this is going to be simplified into an updated UVA protection rating standard at some point but right now, you have to do your research or alternatively just do what I said here. Uvmune 400 also doesn't sting eyes like others do. (edited)

All suntan lotions need frequent application. Theres no such thing as all day lotion.

This is 4 star rating. You will barely find an spf50 without 4 the trick is if its not on the front and its spf 50 its 4 star if less than spf50 its likely 3 star (which is below NHS recommendations). All 5 star products have it on the front. If not on the front then I usually avoid with the earth getting hotter and more rays getting through than ever.

This is an alcohol based liquid. If you want full protection, get P20 Kids or La Roche-Posay Uvmune 400. (edited)

Totally different. UV water was discontinued.
