Using Oral Supplements/Vitamins in Cosmetics

Subject: Using oral vitamins/supplements in cosmetics

It is generally not recommended to use vitamins or supplements intended for oral consumption, such as collagen or hyaluronic acid tablets/capsules, by dissolving them in water for use in cosmetics. This is because oral supplements often contain fillers, binders, or other excipients (like starch or binding powders) that are added to adjust the dosage or form the tablet/capsule. These impurities are not suitable for cosmetic formulations, which typically require ingredients of high purity to ensure efficacy, stability, and safety when applied to the skin. Using impure substances could potentially lead to unexpected reactions or poor product performance.
