Blog with Dr. IrwinTag >> Sunscreen Can running make facial sagging worse?Posted in Sunscreen, Sun Protection, 2011 on Dec 31, 2011 | Permalink I began running in recent years, but have heard that it can actually make your facial skin sag because of the pounding force. I know exercise in general is good for skin because of helping with circulation, but is running a no-no?? Thank you!
There is no data on this but ...... I've treated runners for many years, have many friends and family who run (including marathoners) and run myself 2-3 times a week. As long as runners... more
What would provide a good sunscreen with a matte finish for oily skin?Posted in Sunscreen, Sun Protection, Skin Care Products, Skin Care, 2011 on Jul 29, 2011 | Permalink Dr Irwin,
I'd love to own a quality sunscreen for face with matte finish. I've tried some that promise so but shine shows up anyway. Could you please suggest? Would you trust quality of sunscreens made by make up - or even clothes' - makers such as Clarins and Chanel? Thanks.
Have you tried the mineral powder makeups with sunscreens that are SPF 15 or above? What about the Jane Iredale SPF 20 powder compact - that might be perfect for you - or look at Bare... more
Why did my brown spots come back after IPL treatments when I wore sunscreen?Posted in Sunscreen, IPL, Brown Spots, 2011 on Apr 04, 2011 | Permalink Hi Dr. Irwin,
I had a two IPL treatments for brown spots/previous sun damage. I was very please with my resuls. I went to Costa Rica a month after my ipl treatment and my spots are back!!! I wore Neutragena SPF 100, a hat and wasn't basking out in the sun. I was very good with reapplying the sunscreen. I am perplexed! What do you recommend? I would get another IPL treatment, but is it really worth the cost? I was so disappointed that after two days in the sun, with heavy sunscreen on, they came back. Is there a better sunscreen then Neutragena 100? Any over the counter creams do you recommend or should I try another IPL? Thanks so much!
Okay - this is good - because there are some important points here. Remember that for brown spots the SPF doesn't matter much as long as it's at least an SPF 30. You want an SPF 30... more Do I need a moisturizer with a sunscreen?Posted in Sunscreens, Sunscreen, Sun Protection, Oily skin, 2011 on Mar 20, 2011 | Permalink Hi Dr. Irwin. My question is about Sunscreens. They all feel like moisturizers but most skin care programs suggest using a moisturizer before a sunscreen. I am 50 and have oily skin but with the use of the skin Medica retinol I do tend to be surface-dry right after washing. Do I need to use a moisturizer or is a sunscreen like Ti Silc spf 60 or SkinMedica SPF 30 enough?
You really don't need an extra moisturizer with the sunscreen if you're oily. Here are 3 options. One, just use the sunscreen alone. Two, use the moisturizer you like and put a... more

How much sunscreen is enough on the face?Posted in Sunscreen, Sun Protection, Sun Damage, Skin Care Products, Skin Care, 2010 on Oct 17, 2010 | Permalink How much sunscreen do I need to apply to my face to get the full SPF?
I read that you need 1/2 teaspoon. I measured it and tried to put it on but it was difficult to put that much on my face. Is this the correct amount and if I don't put that much on am I not getting that much protection? Does it differ with chemical versus physical sunscreen?
I know what you mean - it's a lot. But I think common sense can apply here and these are guidelines really. If I were outdoors, midday in Hawaii and surfing, I would apply all that and... more Is it okay to use tretinoin/Retin A, etc if I live in a sunny climate and am driving a lot?Posted in Sunscreen, Sun Protection, Sun Damage, Skin Care Products, Skin Care, RenovaRetinoids, Renova Retinoids and Vitamin A Creams, 2010 on Sep 06, 2010 | Permalink Hi Dr Irwin,You are a very kind person to answer questions on your blog because I'm sure you are a very busy person. I can't personally visit your country to make an appointment with you but I do buy products through your links so I hope that helps. My question is regarding tretenion. I live in a very hot dry climate and I am exposed to the sunlight many days that shines into my vehicle as my job involves driving. I want to use tretenion but I read that you don't use it in summer. Could I be doing more damage to my skin by using it considering my climate with my particular job. I am very diligent with sunscreen and I reapply every few hours.
Thank you! Sorry it took me so long to get to your question since it's a good one. Car window glass does not block all UV rays as you pointed out. Window glass usually blocks UVB but... more Is the zinc content more important than the SPF in a sunscreen?Posted in Sunscreens, Sunscreen, 2010 on Aug 17, 2010 | Permalink I have melasma and noticed that you recommended a couple of sunscreens with high zinc in them. Is this more important that a high spf? Thanks...Jennifer
Glad you asked to clarify this! The short answer is yes! As long as the sunscreen has at least an SPF 30 and is appropriate for the situation - i.e. water resistent when you're in... more
Do I need to reapply my sunscreen at the end of the day at my office?Posted in Sunscreen, Sun Protection, 2010 on Jun 25, 2010 | Permalink Love your site, I’ve learned so much – Thanks!! I have a question on sunscreen. My morning routine includes using a separate sunscreen, currently the Skinceuticals Sheer Physical UV Defense 50. Throughout the day I blot my face w/ tissue to control oil. When I leave work around 5, is my skin still protected or does the sunscreen lose potency by sitting in an office all day?
Thanks!
You're welcome!! Sunscreens do degrade on the skin over time slowly with exposure to light, blotting or wiping the skin, exposure to our natural skin oils, etc. I've never seen a study... more
Is Heliocare helpful for added sun protection?Posted in Sunscreens, Sunscreen, Sunburn, Sun Protection, Sun Damage, 2010 on Jun 25, 2010 | Permalink Several dermatologists have recommended Heliocare for added sun protection. What is your opinion on Heliocare? Thanks for all you do! Bonnie
This is a tough one because since Heliocare is sold as a supplement, it is not regulated by the FDA. That means that side effects from it's use may go undetected for some time. I cannot... more Is sunscreen in makeup enough?Posted in Sunscreen, Sun Protection, Sun Damage on Apr 06, 2010 | Permalink
Dr. Irwin,
My makeup (bobbi brown) and moisturizer (purpose) contain spf in them. Is it necessary to use an additional sunscreen for everyday exposure? I live in Northern California where it is often sunny. Also, my husband wears a moisturizer with spf in it. Is that enough coverage for everyday exposure? Will the amount of spf found in moisturizers and make-up prevent wrinkles and sunspots? We are both very fair and burn easily.
Thanks,

I am a 31 year old woman who lives in Seattle. I wear sunscreen every day, the Replenix brand with antioxidants. If I use this product, do I still need to use an anti-oxidant serum too?
