Bars from Mars is a project that integrates self-love and environmental awareness. I was in the end of my PhD in biotechnology engineering when the world stopped because of the pandemic in 2020, and I realized that we should rethink our actions and be more aware of the influence of our consumption choices in the planet. I decided to start a project that could have a social impact using my academic knowledge. It was when Bars from Mars was conceived.Conventional cosmetics in bottles are made of 80-90% water. The idea is to use less water and create highly concentrated products in bars. Just by choosing products in bars instead of bottles, we are reducing water use and single-use plastic consumption. For being highly concentrated, cosmetics in bars last longer than their liquid counterparts. Therefore, one shampoo bar for example can replace until 2 bottles of shampoos, meaning 2 less plastic bottles in the world. Bars from Mars products are vegan, palm-oil free, natural, plastic-free and cruelty-free. Every ingredient is carefully chosen based on their benefits and source material. This project shows that it is possible to have beauty products with minimum impact on the environment, without compromising quality.
