Hello, I use sunscreen a few Year, but, generally sunscreen that offer a strong protection for Uva ray ( ppd 20-30) are whitening , or very very shining.
Just Anthelios w gel spf 40 PPD 19 are invisible to first application, but second application is white.
Do you Know a very very light sunscreen invisible with PPD 20 minimum?
I tried every line of : BIoderma, Anthelios, Avenè, Roc, Galenic, Ducray, Klorane, Uriage, some vichy.
Usa sunscreen : Elta Md, Paula Begoun, Skinmedica.
Japan sunscreen : Shiseido Annessa, Fancl, dr:c:Labo, Sofina.
For shining effect I haven't problem I use OC eight gel for mat effect or a Blot powder MAC, that are compatible with all chemical filter.
Thank You.
Well, the good enough sunscreens with good enough UVA protection tend to be white.
The reason is either they contain TiO2 for UVB and UVA II protection (L' Oreal group) or higher amount of Tinosorb M (UVA II and I protection; it is very white; Avene, Roc, Galenic, Ducray). American sunscreens tend to contain ZnO (which again is whitening, though not as much s Tio2).
The shine comes from waterproofing agents and / or being able to disperse the sunscreen agents evenly in the product and later on the skin (Film formers). And from the oiliness of the chemical sunscreens.
Oiliness and shine can be counteracted but whiteness not so much.
The general rule is the whiter the finish the better UVA protection you have.
I have found a very good sunscreen: matter, not so whitening and has very good sunscreen agents: Avene Emulsion SPF50+ (new for 2009). Though I always put a sunscreen on the top which contains 28% ZnO and 10,6% TiO2 just to be on the safe side
