Synthetic dyes have become widespread recently because they are easy to make and cost-effective. Nevertheless, natural shading has become increasingly popular again due to its safety and environmental properties.
2. How to keep the color on the skin
When you apply gums to your skin, the particles of the fine powder stick are due to the static electricity in the skin and natural oils. The moisture in the skin temporarily sticks the color and forms a gorgeous colored layer. These colors are easily removed with water and soap compared to permanent pigments applied in tattoos or makeup.
3. The function of the skin
The pH of the skin is slightly acidic, which will affect the appearance of the color. Natural dyes are sensitive to pH and vary according to the color of the skin’s pH. For example, turmeric may get a pale yellowish tone on oily skin because it reacts with skin sebum oil.

Some factors determine the long-term existence of color on your skin:
- Skin Type: More color is retained on oily skin due to oily content.
- Humidity: High humidity helps to have better color.
- Clothing: The clothes worn may affect the amount of color transferred to the skin.
5. Safety and environmental issues
Sprinkling red color is usually safe, but some synthetic dyes can irritate the skin or trigger an allergic reaction. It is best to use natural, environmentally friendly ditches to avoid risks. Correct handling of second-hand colors can also protect the environment.
Celebration of conscience
