I feel like tearing my hair out over this. I have been using physical sunscreens for about 11 years to protect my skin on a daily basis. Before this I used a chemical spf in a daily facial moisturiser. So far I think my skin has benefited from my use of sunscreen I don't really have any wrinkles or lines at all in my late 30's but I keep hearing all sorts of mixed messages about sunscreen, what is and isn't safe etc.
For example I prefer to use a physical sunscreen because I can use that over serums where as a chemical sunscreen should be applied to bare skin. Also I heard that chemical sunscreens can cause a reaction in the skin which causes oxidation and further skin damage but on the other hand I've also heard it said that chemical sunscreens protect better from ageing UVA light.
The sunscreens I use have zinc oxide and or titanium oxide. I thought they were safe but now I read that both these ingredients are potentially harmful to the skin especially if they are nano particals. The idea seems to be that the particals can enter cells where they can basically damage the cell from within. I am not 100% clear on this but I also think their is some suggestion that even the larger particles of zinc and titanium (that cause a white cast) may not be 100% safe.
Now to top all this off their is a new sunscreen (Ladival) that claims to protect against the most damaging rays of all Infrared A, I'd like to try it but it contains nano particles of Titanium oxide.
I just feel very confused, I just want a good, safe daily sunscreen that can block out the maximum amout of damaging rays that is possible but there seems no straight answer. I think my skin is better than my peers wrinkle wise at least in part because I shunned the sun and wore spf all these years so I do intend to use it and feel it helps but I am worried that I am storing up problems for myself in the future!
Arrgh, any thoughts on this? |

As long as the zinc is non-nano, don't fear anything. Zinc oxide will trump Titanium Dioxide cause zinc protects thru the full spectrum of UVA (aging) rays while Titanium Dioxide does not.
Many people, including myself, use and love Burnout sunscreen. They have several formulas.
There's a reason it's popular on the 2 most popular skin care forums on the net. This one and skincaretalk.

Amazon or ebay are great places to buy it.
There are other very good ones. Do a search on this site. |

Tinosorbs, and Mexoryls to a lesser extent,are chemical ingredients that are very photo-stable compared to what you typically can find in a US sunscreen. Usually found only in European sunscreens. Although you can order online European
sunscreens through certain sites. Just have to google search. |

L'Oreal has the patent on Mexoryl. It can be found in Canadian brands/stores as well as European.
L'Oreal brands = La Roche Posay, Biotherm, Vichy and Ombrelle (now Garnier) is very affordable.
Tinosorbs are in are (Canadian) Bioderma products.
Whatever product you go with be sure it is photostable and has UVA protection. |

Thank you for your replies the burnout looks really great but it seems difficult and expensive to get a hold of here in the UK.
If zinc oxide is safe then I would probably prefer to stick to a physical sunscreen as I like to be able to apply it on top. But I will look into the chemical sunscreens you both mention.
I am also very interested in the Infrared A issue as far as I can tell sunscreen doesn't really address this at all and that antioxidents internal and topical seem the best solution again I need to find more info on this.
Thank you again for your responses  |
