Analysis of the Newsletter from MUTHA

1. Contents of the Newsletter

The newsletter from MUTHA reveals an interesting revelation about the founder's allergy to L-Ascorbic Acid, a common form of Vitamin C in skincare products. The founder shares their journey of developing the No.1 Serum with an MIT chemist, where they discovered their severe allergy to L-Ascorbic Acid during the testing phase. After multiple failed attempts and skin reactions, they identified the culprit and switched to THD (Tetrahexyldecyl Ascorbate), a stabilized and oil-soluble form of Vitamin C. The newsletter emphasizes the importance of using stable and effective forms of Vitamin C in skincare products.

2. Products

The main product highlighted in the newsletter is the No.1 Serum by MUTHA, which features THD (Tetrahexyldecyl Ascorbate) as the hero ingredient in place of L-Ascorbic Acid. This serum is designed to provide brighter-looking skin, improve dark spots and uneven tone, offer antioxidant support, and enhance long-term radiance. The newsletter underscores the quality and stability of THD over L-Ascorbic Acid for effective skincare benefits.

3. MUTHA Store
