Made with safe, and effective preservatives, ARCONA products are made to order in small batches to keep them fresh and assure the potency of active ingredients. Small batches guarantee that products are delivered to the marketplace immediately and used while they are most effective. We also offer some formulations that are preservative-free (self-preserving). ARCONA products are not homogenized, and apparent irregularities in the color or texture of products signify the living nature of our ingredients. We also cold-process many of our ingredients so that they are not destroyed by heat. Only those ingredients required to achieve the best results go into our products.
