- Many cancer-causing agents such as Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are part of a large group of lab-made chemicals known as perfluoroalkyl and poly-fluoroalkyl substances (PFAS). They do not break down easily and stay in the environment and human body for long, thus getting their name as “forever chemicals”. Trace levels of PFAS are added to cosmetics to condition and smooth the skin or for product consistency and texture.

- The most commonly parabens used in cosmetics are methylparaben, propylparaben, butylparaben, and ethylparaben.

- Sunscreen is an armour against cancer-causing UV rays. It even has to be reapplied every 2 hours for maximum protection. Bad sunscreen ingredients can cause severe effects as it is more frequently used among the skincare products.
- Oxybenzone is a common chemical sunscreen ingredient linked to allergies, hormonal disruptions and potential ecological damage.
- Oxybenzone (BP-3) and octinoxate (OMC) are two common dangerous ingredients in sunscreen that are also known to have endocrine-disrupting potential and can penetrate through the skin and enter the systemic circulation.
- Use mineral or physical sunscreens which contain titanium dioxide or zinc oxide that protect you by deflecting the sunlight instead of using toxic sunscreen ingredients.
