On using finished products in your formulations/modifying store-bought products

Please don’t use store-bought cosmetic products as ingredients in your formulations; aloe vera gel is probably the most common ingredient I’m asked about doing this with. This is quite an expensive way of getting ingredients, and these finished products are not designed to be used as ingredients in a secondary formulation. They may contain ingredients that could conflict with the rest of your formulation, resulting in failure.

Similarly, please do not try to modify store bought cosmetic products you’ve purchased; you risk compromising the preservative system and the entire formulation.
