Recommended Posts

I know it protects the skin, but does it help/protect the red marks...will they not get darker...or lighter...

and does it prevent a tan too...how long do you need to be in the sun to tan/ and hurt ur red marks.

If I'm outside for more than 5 minutes I wear mineral sunblock.

Chemical sunscreens suck because they break down easily, get something with zinc and titanium dioxide if you can....it IS white colored and if you're dark skinned it might look bad....if that's the case and you need clear chemical suncreen,be sure to reapply as often as the bottle says.

I usually only have to reapply my mineral suncreen once, it stays on the surface of my skin well.

I'm freakishly white and the instances I was forced to be stuck outside all day in the Arizona heat didn't affect my skin color AT ALL because I was wearing my mineral sunblock.So yes, it really does prevent tanning lol.

I've heard that sun exposure DOES make red marks darker,so it's important to wear some. Even if the sun won't affect YOUR red marks that way,sunscreen keeps your skin healthier.(imo)

it protects against UVA and UVB rays which is the number one contributor to wrinkles and cell damage. If you have acne scars or discoloration of the skin, it will worsen with sun exposure. To lighten these area you have to wear sunscreen.
