Anti-Aging: A new reason why you need more than just UV protection

Fact: UV isn’t the only cause of skin aging from the sun… You need protection from IR, too.

That’s right: Just when you thought you had it the whole anti-aging thing down, science is showing we have more than UV radiation to worry about: infrared radiation (IR or IRA)

What is infrared?

IR makes up more than half of the solar spectrum. IR penetrates deeper into the skin than UV rays. -This is a scary thought, because  well, deeper in the skin means more damage to the skin. img_3319

“Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than (the) visible … the primary source of infrared radiation is heat or thermal radiation… The higher the temperature, the more the atoms and molecules move and the more infrared radiation they produce.”

…According to California Institute of Technology’s CoolCosmos.com Read the whole article here 

IR manifests itself as heat on the skin, so when you’re outside and you’re feeling the heat, IR is doing it’s evil work on your subcutaneous layers.

So, what does this mean for your skin??

Basically, THIS: (see pic)

IR Radiation: basically baking your skin

 

IR causes free-radical production deep in the skin, essentially cooking the skin, causing free radicals to form, creating damage, hyperpigmentation, and of course: wrinkles. See my post on Free Radicals here.

What can you do?

It takes anti-oxidants to neutralize damage, along with broad-spectrum sunscreen to protect. A couple of my fave go-to “superscreens” combine the two for you:

SkinMedica’s Total Defense + Repair line features cosmetically-elegant superscreens in both tinted and not-tinted versions. I love this one.


Another newer and fabulous superscreen is Obagi’s Sun Shield TINT SPF 50, providing a matte finish and two shades to choose from: Cool and Light.

These easy-to use IR-defense products are making it easy to protect from UV and IR on a daily basis.

Check them out, give them a try this summer, and until next time: stay fabulous, my friends!

These Villains are the Cause of Skin Damage, Part 3

If we want to look at our anti-aging practices from an informed and discerning perspective, it’s good to know what’s going on in there that causes wrinkles (and other not-so-fun manifestations of skin aging). So far, we know about three main things that happen in the skin when damage is caused. Click HERE for the 1st Villain I wrote about, Click HERE for the 2nd in the series. Read on for the 3rd biochemical phenomenon in my series:


Advanced Glycation End-products (AGEs)

AGE is a a conveniently-coincidental acronym for Advanced Glycation End-products, which are the evil little products of a reaction between glucose (sugar) and proteins… Specifically collagen and elastin in this case (glycation).
Yes, it tastes good, but excess sugar in your diet screws up more than just your waistline.
How does it cause aging? 
Glucose is good, of course, in the way of providing energy. But when there’s extra glucose, it rumbles with our collagen and elastin. This process produces AGEs, which make these fibers crispy and easily breakable. This reaction contributes to inflammation, slowed/inhibited growth of cells, and wrinkles (oh my!).
To simplify, think of it as turning your normal, elastic rubber band-like fibers into an old, dried out and crumbly rubber band. When AGE’s wreak havoc, your rubber bands are in an accelerated aging state, causing that loss of elasticity, sagging, and wrinkles.
You know all those old, crumbly rubber bands in the back of your desk drawer? That's your elastin after AGE's.

You know all those old, crumbly rubber bands in the back of your desk drawer? That’s your elastin after AGE’s. Yikes!

In an article for Prevention, dermatologist Dr Frederic Brandt (well-known for his research in AGE’s) breaks it down further: “Besides damaging collagen, a high-sugar diet also affects what type of collagen you have—another factor in how resistant skin is to wrinkling… The most abundant collagens in the skin are types I, II, and III, with type III being the most stable and longest lasting. Glycation transforms type III collagen into type I, which is more fragile.
The article goes on to describe that “AGEs deactivate your body’s natural antioxidant enzymes, leaving you more vulnerable to sun damage—still the main cause of skin aging.”

yikes! What Now?
1) It’s time to build some new Collagen. If you’re not already, start using a Retinol or Retinoid.
My favorites for sensitive or dry types:
My favorites for resistant or oily skin types:
Rx Tretinoin .05 or Tretinoin .1 creams

2) Diet:
Cut down on simple sugars in your diet. From a dietary perspective, refined sugar seems to impact glycation about 10 times more than glucose.
Yup, just another reason… Sorry.
Judgmental cat seems judgmental, but he really just cares about your complexion.

3) Use topical antioxidants.
These guys are ONCE AGAIN a great way to cut down on all the domino effects of damage. . Click HERE to read more about them. 

4) Try a Targeted Treatment Cream: One of my fave go-to’s is Skinceuticals AGE Interrupter. Give it a Go if you’re in the market for a rich, cosmetically-elegant treatment cream.

And Until Next time, Stay Fabulous My Friends!
