If you like science backing your skincare routine, look no farther than Adsorb. Yes, you're reading correctly: ADsorb. The key ingredient in Adsorb's products are ostrich egg yolks, which contain a high percentage of antibodies, giving the animal the strongest immune system of any other species. The yolks are extracted without harming the Ostrich and put into the products to help serve as a defense mechanism for the skin. It's the first brand to utilize this research, which most commonly was used in expensive medical treatments.
