You get the SPF of the first product that you put on your skin.

Here are a couple of links to a dermatologist answering the OPs original question:

Why you should always apply your sunscreen first and the different types of sunscreens (traditional vs chem free):

Does makeup with SPF really protect you from the sun?

How to apply chem free sunscreens (you need less than traditional sunscreens):

There's a wealth of other info on sunscreens, how to apply them properly, etc. on the site. So far as sunscreen vs sunblock, I think that sunscreen can refer to any sunscreen (traditional or chem free) but that sunblock is often used when referring to the chem free sunscreens.

For those of you like Gevans7 (and myself) who are concerned about the chemicals in sunscreen, here is a "recipe" for an all natural, nonchemical-based sunscreen. I personally haven't tried it, but plan to get the ingredients to make it. It is important to find a high-quality zince oxide that is specifically for cosmetic applications - make sure it is uncoated and not micronized or classified as a nano-particle.

Homemade Coconut Oil Sunscreen Recipe

1/4 cup coconut oil
1/4 cup shea butter
1/8 cup sesame or jojoba oil
2 tbsp. beeswax granules
1-2 tbsp. zinc oxide powder (optional)
1 tsp. red raspberry seed oil
20-30 drops carrot seed essential oil
Essential oils of your choice (lavender, rosemary, vanilla, and/or peppermint are nice)

1. Using a double boiler (or a small pan over very low heat), melt your coconut oil, sesame or jojoba oil, beeswax, and shea butter together. The beeswax will be the last to melt.
2. When the beeswax is melted, remove the mixture from the heat and let cool to room temperature. If youíre using zinc oxide, whisk it in at this point, being careful not to create a lot of dust. If there are some lumps, thatís OK. They will break up when you whip the body butter in step 4.
3. Move the mixture to the fridge for 15-30 minutes. You want it to start to set up, but still be soft enough to whip.
4. Take the mixture out of the fridge and using a stand mixer or hand mixer, start to whip it. Drizzle in the red raspberry seed oil, the carrot seed oil, and any essential oils of your choice, and continue whipping until the mixture is light and fluffy.
6. Use as you would any regular sunscreen. Application rates will depend on your activity and exposure to water. Store in a glass container in the fridge between uses.

"Nor my pores blocked." Choose products labeled non-comedogenic.

Sunblock and sunscreen mean the same thing.

Sunscreen is important because even if you don't burn, leaving your skin (no matter what the tone) exposed to UVA/UVB rays still increases your risk of skin cancer by a ton. Sun exposure is also a cause of premature aging of the skin cells. There are plenty of products that don't contain Vitamin A and won't clog your pores. I like the Neutrogena Broad Spectrum products since they don't have a sticky feel, protect against the full spectrum, and doesn't aggravate my acne.

I'm impressed. Lec and Anarie both sound educated on the subject. I live in S. Florida, travel south (Caribbean/Mexico/South America) am olive toned and NEVER wear sunscreen. I don't want the toxins on my body nor my pores blocked.. I also never burn. My blonde son does and I do want him to wear sunscreen. I used to use a sport screen on my face in my 30's but as I got older, the sweat issues became extreme and I couldn't stand the sunscreen.

Now, can you tell me the difference between sunblock and sunscreen??
P.S. - my doctor still wants me to use sunscreen.

Thanks - that makes sense.

Like I said, I do not pay for my stuff, so it's not like I am running out buying higher spf products, right now I have 3: 15, 20, and 25 that I rotate, today I will be spending a lot of time in the sun - so I think the question was, really...does putting on make up with an SPF matter if you are already putting on a sunscreen?

I guess not, lol.

Probably closer to 20 SPF combined. The amount of moisturizer/makeup you have to use to get the full SPF is not realistic compared to how 90% of women put on makeup.

As it is, you get ridiculously diminishing returns after about SPF 35. That protects from 95% of UVA/UVB rays, SPF 40 protects 98%, etc. For that reason, my base layer is SPF 40 sunscreen that has moisturizer in it. Sunscreen has a higher concentration of the SPF acting compounds than other products so that's why it's important to use actual sunscreen. I've been known to burn on a cloudy day in the middle of winter so I am *always* sunscreened up.

Thanks but that doesn't quite answer the question.

So, let's say it's not a full 25 for the first - I know it rubs off, sweats off, etc. How much am I putting on - hypothetically the numbers are correct 25 +15.

Am I putting on 40...or just 25 in, the first layer is the one that counts?

I do not pay for my I don't pay extra or less. lol...I do not pay a dime for them. Sometimes I am given spf 20, 15, 30, 25 - it does not matter to me...I was just curious about the total number. Thanks.

No, it's not additive. It's also not really 25. The SPF ratings are based on theoretical lab tests, not on real-life conditions. In reality, you sweat and rub some off, so you get about 10x protections regardless of what the label says. I used to pay extra for 45, but after I heard that it's really mostly marketing, I focus on the type of product rather than the number-- I use a spray when I'm going to be active outside, and a moisturizer for everyday use. The spray stays on better when you perspire.

And when I thought about it, paying for SPF 45 was kind of silly even if it did work. The number supposedly refers to how many times more you can stay out without getting burned. Well, even in bright desert or on the water, I can stay out 15 minutes without a burn. Multiply 15x45 and you get over 11 hours. I'm not going to be outside for 11 hours without re-applying!

Something I was wondering, if anyone knows....

So, my moisturizer is SPF 25, and my makeup is SPF 15. Am I putting on a total of SPF 40? Or only the first layer of 25 applies, and the 15 does not matter?

Just curious as I was putting on my makeup today...
