Stephanie says: Is it true that it is better for your skin to sleep on silk pillow cases?
The Left Brain believes:
There is some evidence, like this Pubmed article, that indicates special silk clothing can reduce atopic dermatitis in children who are prone to that condition. However, I have can’t find any evidence that sleeping on silk pillowcases is really better for your skin. Nonetheless, one brand, Silkskin Antiwrinkle Pillowcases, says they actually fight the signs of aging. Here are a few claims from their website followed by my comments:
1. Gives your skin the chance to breathe naturally
While your skin does perspire and while certain chemicals can clog your pores and cause acne, skin does not really “breathe” so silk doesn’t really make a difference in this regard.
2. Because moisture levels are being maintained throughout the night, deeper lines and wrinkles are not forming.
Moisture loss causes dry scaly skin, not wrinkles. A pillow case can not stop wrinkles from forming.
3. Different from run of the mill silk pillow case as it is made from organic silk which contains amino acids, the building blocks of your skin.
ALL silk is made of amino acids, so the fact that this silk is organic is completely irrelevant. And the amino acid profile of silk is different than keratin protein, which is what skin is made of. And, even if it were the same, it’s not like the amino acids leap off the pillowcase and attach to your skin.
4. Organic silk also has the same pH balance of your skin.
Measuring pH really only makes sense when you’re talking about a water solution. Yes, skin has a optimal pH balance, but the pH of fabric you’re sleeping on is really irrelevant.
5. When sleeping on this pillowcase, your night cream is fully absorbed by the skin and won’t rub off like it usually does, therefore allowing the cream to work to maximum effect.
I’m curious if Silkskin has any actual data to back up this claim. I suppose it’s possible that silk is less absorbent than cotton, which means it could absorb less oils and moisture from the surface of your skin. But even if silk is less absorbent, just the friction of your skin against the fabric as you move around in your sleep is still enough to wipe some of the lotion off your face. Without some kind of test data to show Silkskin has a beneficial effect, I’m skeptical on this claim.
6. Silk stops you getting the dreaded ‘bedhead’ as your hair will simply glide over the pillowcase.
Bed head isn’t just caused by rubbing your hair across the fabric of the pillow. It’s also caused by the warmth and moisture of your perspiring scalp saturating your hair and reforming the hydrogen bonds (also known as salt bonds) in your hair, which results in the bizarre hair configuration you wake up with. Since silk doesn’t stop you from perspiring, it probably has little effect on bed head. But once again, if there’s test data to the contrary I’ll gladly reconsider my position.
7. Dust mites cannot live on silk so the pillowcase is excellent for allergy sufferers.
This is the most intriguing of all Silkskin’s claims. While I found references to very tightly woven pillowcases being used to prevent dust mites from penetrating into pillows, I could not find any legitimate scientific source that answered this question one way or the other.
The Beauty Brains bottom line:
There may be some legitimate benefits to sleeping on silk, but Silkskin makes a number of definitive claims without providing much information to back them up. Maybe it’s true that dust mites can’t live on silk, but I’d rather not take the word of the company trying to sell me the product as proof. A little independent confirmation would go a long way toward making me feel better about buying this product.
