How to apply the right amount of sunscreen?

I bought Neutrogena UltraSheer Dry-Touch Sunblock SPF 55 for my face. It says to apply generously, but how much is generous enough? For example, a dime size amount should cover how many square inches of my skin?How to apply the right amount of sunscreen?
Actually, you chose the right sunscreen! Neutrogena's Ultra Sheer Dry-Touch SPF 30 and SPF 45 aren't that great. They only protect against UVB rays (causes burning) and not UVA rays (causes tanning and alters skin's DNA -%26gt; premature wrinkles, damaged collagen and elastin, etc.).





Reason --%26gt; SPF 55 has Helioplex (so does SPF 70). SPF 30 and 45 do not. Helioplex stabilizes the ingredient Avobenzone, which protects againts UVA. Thus, Neutrogena's SPF 55 and 70 offer true Broad-Spectrum Protection (UVA and UVB).





Anyway, it's recommended that for the face only, a teaspoon of sunscreen/sunblock should be used. Half a teaspoon for the neck area. It's also recommended that you apply sunscreen/sunblock, let absorb and dry for 20-30 minutes and apply a little more again all over the areas you previously applied sunscreen/sunblock to. This ensures effectiveness. The amount of sunscreen/sunblock for your second application depends entirely on you. You don't need another teaspoon of it on your face (you could if you want but you could do less). Reapply every two-three hours.








^ I know its a lot. I'm generally really bad at reapplying sunscreen. Anyway, hope that helps! :)How to apply the right amount of sunscreen?

Okay ...but


I don't think it really matters that the SPF is 55. SPF (Sun Protection Factor) only measures protection against burning (UVB rays). UVA rays causes premature aging and in my opinion, UVA can be equally, if not more damaging to the skin...

esp. when you're using sun-sensitizing products (such as the GA cream you use). I think that with Neutrogena's SPF 55, what's really important is that it protects against both UVA and UVB. The number doesn't matter.

If anything, you could try searching for L'Oreal's La Roche Posay SPF 15 moisturizer. It contains Mexoryl (a really good UVA filter). Low SPF and great protection! (and it's a moisturizer to add). ...

But this product is fairly new so you may have trouble finding it (oh, and drawback is it's kind of expensive -%26gt;$30 and up). I live in California and it's only available at CVS pharmacies. ...

If you want lower SPF, you could also check out Aveeno's new line of SPF products. They offer some good, stable products too. Anyway, hopefully everything works out for you! :)
