Skin Care Myths Explained
From old wife’s tales about stretch marks to urban legends, the myths and stories about skin care that some believe to be true have many an expert confounded.Five common skin care myths are explained below.
1. Prepare your skin for summer sun on a tanning bed. Tanning beds are dangerous because of the concentrated UVA rays they emit. These are the same rays you get from the sun that cause premature aging and skin cancer. Getting a light tan on the sun bed does not protect your skin from further damage, it just means you have already exposed it to harmful rays. Tanning does not produce more melanin in the skin, it just brings it to the surface.
2. Application of olive oil can prevent pregnancy stretch marks. Stretch marks are caused when the sub-surfaces of the dermis split, usually due to expansion of the skin beyond its elasticity ability. This can occur during pregnancy or because of excessive weight gain. There are no topical preparations that will prevent this scarring from occurring. A healthy diet, hydration and regular exercise are the best ways to ensure your dermis remains healthy and retains its elasticity.
3. You can stay in the sun longer if you use a higher SPF sunscreen. Believe it or not, an SPF of 15 will block about 93% of harmful UV rays. A 40 SPF only blocks 97% of rays – an increase of only 3%. A higher SPF does not last longer than a lower one, and should be re-applied as regularly as a lower SPF sunscreen. Make sure your sunscreen blocks both UVA and UVB rays, and put it on before you go into the sun.
4. You don’t need sunscreen if you have dark skin. A darker skin tone, whether a Mediterranean olive-toned complexion or the skin tone of a person of color, does not give the person extra protection from the sun. It only means that they have an increased level of melanin. Although this does decrease the risk of skin cancer from the harmful UVA and UVB rays of the sun, it is only a slight decrease, and people with darker skin tones must use sunscreen and take the same precautions as those with a fairer complexion.
5. Eating chocolate will give you acne. Acne is not caused by anything you eat. Acne occurs when the dead cells that your skin sheds stick together and block gland openings. This causes a back up of the oils that naturally occur in your skin. Bacteria on the skin react to this and make the condition worse. One type of food is not going to cause acne, but a healthy diet will promote a healthier skin and body.
