How do I know what the spf is when making suntan lotion?

That depends on how much you add to your lotion. My understanding is that if you want an SPF of 20+, you need to use 25% of the weight of your initial amount of lotion. That is if you use 8 oz of lotion, you would need to add 2 oz of zinc oxide to get an SPF of 20 or so. That is my understanding. I mostly use this product for diaper cream. Oh, also zinc oxide shouldn't be ingested so when working with it, make sure not to inhale it.

This product has SPF4. Low SPF but I tan easily so works for my skin. If you burn easily, avoid prolonged exposure with this product only.

I apply it and leave it on after washing my face. My foundation has sunscreen (just 15 SPF, I think) in it. If I'm going to be spending time in the sun, I use a 30 SPF on my face--no particular brand.

The label on the hat indicated so, but not sure how to verify. I did wear a sun hat that wasn't labeled spf protected and can tell you this one is cooler on my headvand face.

The two tablespoons of zinc oxide per cup of cream will give you an SPF of 20. So one will give an SPF of 10. I got this info from various sunscreen recipe sites. An SPF of 15 to 20 is more than enough. If you usually burn in 15 minutes an SPF 15 will give you 3:45 of exposure (15 SPF * 15 min = 3:45). Anyway, I've learned that any cream with a high SPF is a waste of money because you usually reapply every several hours anyway. Also, the base cream that you add the zinc oxide to might also have an SPF. For example, coconut oil has an SPF of approximately 4. I hope that answers your question.

I believe the spf component is absorbed along with the firming moisturizer to help those of us who don't always remember to wear sunblock every day. Also consider that a lot of these proprietary ingredients are mixed together before they are added to any specific cream, night or otherwise.

Hi George, 1TBS + 4TBS of any lotion (home made or store-bought) will give you about 20 SPF, here is a great link that explains how that works: http://www.livestrong.com/article/88858-add-zinc-oxide-regular-lotion/ And this links gives a great recipe for DIY Waterproof Sunscreen (it's from one of our lovely customers): http://www.realfoodrn.com/diy-waterproof-sunscreen-thats-good-skin/ Hope this helps :)

It can be used in the sun or at the tanning booths.... It does not have any protection factor, if using outside by itself only about 15 mins depending on your skin type. You can wear it under suntan lotion which has some spf (sun protector factor) 2-4-6-8-15 etc. It accelerates to tanning.

I use the coconut as a night time moisturizer. Eminence has a couple day creams that have SPF in them

It doesnt specify if it is for indoor tanning or both. I would imagine you could use it outside as well. There is no listed SPF either. I have used it outside and was fine. I dont normally burn though in the sun.

Read the product description it should tell you if the sunscreen is tinted. It should say something like "universal tint" or "protective fluid to enchane natural skin tone. The daily Eltamd SPF 40 sunscreen is not tinted. Try Skinceauticals sunscreen products.

No, there is no spf. Additional to that, you should always use separate spf by itself. That is what my dermatologists have been recommending me. Also, use it everyday even during the winter ;)

I made some sunscreen for my daughter, using coconut oil...and 3 scoops of Zinc powder....and it wound up being SPF35 so yes. It's 10spf...maybe even a bit more...but not much

What kind of marks? I've noticed more sunspots on my face since using the product but I never put the two together. Is that what you mean?

I've been using the rapid tone repair (night). The one with SPF30 must be for daytime. I am on my second bottle and I usually use moisturizers once only. I've used so many moisturizers I couldn't count them. This doesn't work miracles (brown spots, etc.) but you can definitely see a difference within a week.

The bottle specifies spf30 which is pretty good sunscreen so according to the mfgr, yes
