What Excess Sun Exposure Can Do To Your Skin
- Exacerbated aging
- Melasma (dark patches)
- Hyperpigmentation (sun spots)
- Breakdown of collagen (fibrous foundation of skin structure)
- Breakdown of elastin (skin's elasticity)
- Enlarged pores
- Loss of tone/sagging
- Pre-cancerous (actinic keratosis) and cancerous (basal cell carcinoma, squamous cell carcinoma and melanoma) skin lesions
- Telangiectasias -- broken capillaries/the dilation of small blood vessels under the skin
- Mottling and sallow skin color
- Rough texture
In addition, researchers have found that significant amounts of these chemicals are excreted into the urine. In other words, this stuff is definitely penetrating the skin and getting absorbed systemically. Even worse, some animal studies show that it does not protect in many cases the key UV-damage pathways.
The most popular sunscreen (active) ingredient in the U.S. at this time is avobenzone (also known by Parsol, butyl methoxydibenzoylmethane, Eusolex, etc.). Maybe a little more safe than oxybenzone, but still is a free radical generator and excreted in the urine. More specifically, the problem with avobenzone is that after it has been on the skin for a period of time, it could actually lead to increased ROS (reactive oxygen species - free radical damage) from what has penetrated a little deeper into the skin.
Another popular chemical is 4-MBC (4-Methylbenzylidene camphor). This endocrine disruptor is a xenoestrogen and possible thyroid disruptor. It also has some UVA blocking capabilites so some manufacturers add it to the other soup of chemicals. Most of the popular sunscreens (in the U.S.) have a combination of these likely toxic ingredients (avebenzone, oxybenzone, or 4-MBC).
When sun hits a chemical sunscreen, it neutralizes the UV rays, but it is now depleted leaving a vulnerable, unprotected area until you reapply another layer of chemicals. Sun hits it... Poof! No coverage in that area. Like poking holes in a sheet of paper... It lets the sun in to wreak its damage.
Chemical sunscreens ...
- Free-radical creators
- Xenoextrogens - false hormones, hormone disruptors
- Bioaccumulative: they accumulate in your body
- May cause cancer
- Can get into your organs and body systems
- Dangerous for pregnant, lactating women
- May alter hormone levels in developing fetuses
- May disrupt thyroid hormones
- Not desirable for use on infants and children
A better alternative in sunscreens ... Mineral Sunscreens
Simply put, you apply them to the surface of the skin, and they act like little mirrors by reflecting the sun off the skin.
TiZo is a great creamy, lotion-type of sunscreen. Great for Normal - Dry skin types. 40 SPF. Water-resistant. Sensitive-skin formula.
