Hey Ya'll,
Well, I was perusing the skincare section at my local friendly Walgreen's today, looking for a new sunscreen (my current one, generic Olay, smells rancid, trash). I read the post in the FAQ concerning sunscreens and was looking for one that was 1)budget-friendly 2)appropriate for use when using retin-a 3)won't break down when used with the wrong makeup or another product containing SPF. I ended up with an Aveeno travel pack, a zippered bag containing travel sizes of 6 products, 3 of which contained SPFs. There's the Daily Moisturizing Lotion spf 15, the Positively Radiant Daily Moisturizer spf 30, and Continuous Protection Sunblock Lotion spf 50. Can I not use the spf 50 SB with either of the moisturizers with spf 15 or 30? I know that layering different SPFs does not add up (spf 50 + spf 15 does not = spf 65) but is there another math formula at work here, like an average (50 + 15 = 65 / 2 = SPF 32.5)? The spf50 SB is such a small sample at .5 oz, I'd like to use that, but am I so limited on moisturizers that I can't use the other products in the bag? Should I return the bag and get a larger size of the SB and a moisturizer with no spf?
I don't use foundation makeup, it just settles into the lines and pores and draws attention, and I don't have a lot to cover anyway, as I'm lucky enough to not have acne scars or pigment problems. Just a dusting of powder, my current one is mineral. Now, I can abandon the mineral powder if I can't use it over the Aveeno, which is chemical sunscreen. The abovementioned post described using plain old cornstarch as a powder. Has anyone here done this? Am I safe to assume that I'll not look like I just put flour on my face? I'm naturally light-complected, a red-head Scot.
I'm sooooo confused....

I don't know much about sunscreen, but I have used the Aveeno with great success (Positively Radiant Daily Moisturizer spf 30), and I use Taz, AND I'm outside much of the day (horses). (and although I don't have the red hair, plenty of people in my family do...I got the dark hair, green eyes...I've got that Scots-Irish skin too)
If you want to be sure you're getting good sun protection, find a zinc/titanium sun block instead of the chemicals. (ie Clinique City sunblock?)
I think layering does help, and definitely adds up...yeah, I've read the thing about 50+15 doesn't equal 65 either. It does in my experience. Another thing I've noticed is that women who DO wear foundation normally have less pigmentation issues and better skin than people like me who normally don't. All that titanmium derived pigment in those products.
Another thing I do every year because I'm in the sun SO much in the summer is I quit my Taz use. All I need is to get sun damage on a Retin-A exfoliated skin. I feel that NO sunblock is that good. I pick up use again in the fall, and I think the break actually helps my skin. I've read research where the on/off use of Retin-A is a good process to use anyway. Works better when you give your skin an extended break.
One of my favorite websites about Retin-A use is Audrey Kunin's site, DERMADoctor.com.

Best to you in your Retin-A use! You've don the right thing! PS. That Scottish skin is very sensitive to the tretinoins. Please start slow and if you get red or irritated, take it down a notch. |

vanbergc,
I like your idea of stopping Retin-A in the summer and that's what I plan to do. I'm a fairskinned redhead, too, and work outside a lot in my yard in the summer. I have a couple of questions for you:
What do you use instead to maintain the benefits you get from Retin-A?
When you go back to Retin-A, does it take as long for your skin to adjust as it did the first time?
Thanks. |

bluugrass, you might want to also check over on make-up alley regarding the layering of sunscreens, as well as using a mineral powder on top of a chemical sunscreen. I cannot remember what is ok to mix and what is not, but I know they discuss this stuff at make-up alley. I know there was 1 ingredient in a chemical sunscreen that shouldn't be mixed with a mineral but can't for the life of me remember!
Here is something I found interesting regarding the photosensitivity and Retin A.
"The other side effect associated with retinoid therapy is photosensitization, which normally occurs at the beginning of the therapy. Patients on retinoid therapy are advised to avoid excessive sun exposure and take precautionary measures (like use of sunscreens) for sun protection. However, after few months of therapy, the skin’s response to UV radiation returns to normal. In certain cases, irritant conjunctivitis has also been reported when the retinoid is applied close to the eye (Torras 1996)." (My bold emphasis.) |

That's great to know, Riley, because it's the opposite of everything I've heard. Now, I worried about irritant conjunctivitis, whatever that is, because one of my eyes has red patches around it that won't go away. |

Yep, opposite of everything I have read, as well. I do use Retin A in the summer and I live in FL. I just make sure to use a good sunscreen that I know works for my skin!
Skippie, the conjunctivitis would be in your eye (think pink eye), but the patches around your eye on your skin, that is probably just irritation from the RA. I would back off and not use it around your eyes for a while and see if the red patches go away. Try putting some Aquaphor on the spots. |

Hey Skippie...
I might step up my use of glycolics just a bit, but mostly I just let my skin be in the summer. It's that few months of "benign neglect," and it seems to work for me. I really pour on the sunscreen however. I don't notice any backsliding in the quality of my skin.
I do have to re-adjust my skin every fall, but I just take it slow and then I'm good.
I'm going to look for that research about pulsing your retin-A use. I'll post it if I find it. |

Thanks, Riley - I'll get some Aquaphor today.
I'd love to see the research if you find it, vanbergc. |

Rileygirl, I did see that in makeup alley, that's why I mentioned it in my post, and I believe it didn't single out any ingredient, I think it just said that the mineral makeup degrades the sunscreen, or to that effect. Now, I did find, at Walmart, a Neutrogena spf 30 PHYSICAL SS, I believe it's not formulated for the face but for body, which brings me to another question: does this really matter? Are we supposed to only use one that's designed for the face, because I don't think I've ever seen that addressed on the forum. And the issue of the physical SS's not degrading, and good with the burning rays but not so much with the aging rays, leads me to think that I now have to order sunscreen from Japan. Is it really all this complicated? Can't I just get a SPF 30 or 50 moisturizer, go back to my Cornsilk powder and be done with it. Does the SS have to be SUNBLOCK and not moisturizer with sunscreen because no one ever uses enough moisturizer to get full benefits of the sunscreen it contains?
Who can paint a reeeeally simple picture for me? I'm not dumb...just have ADD. Too many facts confuse me sometimes and I have to run get my Adderall. (Wait a minute, I know...I'll answer that in 30 minutes, just let me swallow this here capsule first...) |

bluugrass, I personally don't think the sunscreen issue has to be that complicated! The problem is finding a sunscreen that a) you like and feels good on your skin, and b) protects Your skin. Unfortunately, it will be trial and error. There are a lot of people who use drugstore sunscreens and are very happy with them. I say go ahead and try your Aveeno spf 30 and/or 50 with your Cornsilk powder and see if that works for you! |

To answer one of your questions, I do remember reading in Dr. Denese's book that if you mixed two SPF's you got the average of the two i.e. 30 + 60 would give you an average of 45.
I would think that you could find yourself a nice moisturizer with SPF (one I use is Neurtogena moisturizer with the 45 SPF, but that Aveeno does sound nice), let it sink in a little and then put your powder over top. It will be up to you to use enough, but because the powder sits on top, I don't think that it should disrupt or lower the SPF of the moisturizer. Let us know how your choice works out for you. |
