BHT is primarily an antioxidant for the formula itself.
It slows oxidation of oils, fragrances and other oxidation-sensitive ingredients, helping prevent rancidity, odor change and loss of formula quality. Its main job is protecting the product, not acting as a treatment antioxidant for skin.
Information approach
Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
