Applications

SAP finds applications in the following aspects due to its versatile properties:

Skin Care Products: SAP is a prime ingredient in high-end skincare products, praised for its stability and efficacy as a Vitamin C derivative. It functions as a potent antioxidant, protecting cells from oxidative damage. Additionally, it promotes collagen synthesis, slowing the aging process and enhancing skin elasticity.
Whitening Agents: This compound plays a crucial role in inhibiting melanin production, thus preventing hyperpigmentation and ensuring a brighter, more even skin tone.
Anti-Aging Formulations: It is widely used in anti-wrinkle treatments and serums. Due to its ability to stimulate the growth of new collagen fibers, SAP helps diminish fine lines and wrinkles.
Sun Protection Products: Being an antioxidant, SAP is an excellent addition to sun protection formulas. It helps mitigate photoaging by neutralizing free radicals induced by UV exposure.

Recommended Usage Ranges

For optimal results, the concentration of SAP should vary according to the product type:

Whitening Products: ≥3%
Daily Skincare: 0.2-2%
Sunscreen Formulations: 0.2-1%

Packaging and Storage
