You make an effort every day to give your body only the best. High-quality foods, healthy drinks and maybe a nutrient or two on top.

But have you ever thought about the substances you put on your skin every day? They should not be underestimated, because the skin eats with you.

For example, a tattoo. The dyes do not remain completely in the skin. They are absorbed and transported through the lymphatic system. One third of the color quantity travels through the body and can settle in lymph nodes or in the liver.

The body can absorb substances very effectively through the skin. On the one hand, this is used in medicine. Medical ointments (e.g. cortisone ointment) or patches (e.g. testosterone patches) have a targeted effect via the high absorption capacity of the skin. However, undesirable substances are also absorbed – such as tattoo ink or hundreds of different ingredients of cosmetic products.

Every day cream, every shower gel, every deodorant and every hair shampoo provide numerous substances that come into contact with your skin every day and are absorbed. Through cosmetics, you can provide your skin with valuable nutrients, i.e. positive “food”. Or you can load them bit by bit with hormonally active substances, silicones, parabens and mineral oils.

The list of harmful substances is long. Too long for a bite of knowledge. That’s why we provide you with the best sources.

Tip: With the Toxfox app , you can scan the barcodes of cosmetics in the drugstore and have the ingredients displayed. In case of harmful ingredients, the app issues a warning.

Some natural cosmetic products are a good alternative – but there are big differences between different natural cosmetic products. I myself am currently looking for brands that are really good. In the U.S., Paleo bloggers praise the natural brand Beauty Counter , which is unfortunately not yet available in Germany. Own brands from the drugstores have not convinced me so far. What does your cosmetics closet look like? Have you already dealt with the issue and sorted it out? Might you want to replace some products soon? Or do you have a tip for really good natural cosmetics? I am happy to receive comments 🙂
