About
3rd Rock Essentials offers chemical-free skincare and personal care products made with earth-derived, food-grade ingredients. The company focuses on safe, non-toxic alternatives that support skin health without endocrine disruptors or other harmful substances. Their lineup includes sunblock, silver-based ointments, liver cleanse supplements, and chelated silver sprays, all designed for daily use.
Founded by Dr. Guerry Grune, a chemical engineer and surfer, the company started with a sunscreen developed to provide full UVA and UVB protection while nourishing the skin. Products emphasize purity: all ingredients are edible-grade, sourced carefully, and formulated to avoid common contaminants. This measured approach aims to integrate natural science into personal care for sustained skin resilience.
The philosophy centers on a simple question: if you would not put it in your mouth, why put it on your skin? This guides their precise, toxin-free formulations that prioritize health optimization through everyday essentials.
