Sodium Ascorbyl Phosphate: what you need to know

Sodium ascorbyl phosphate or SAP is an extremely safe, stable and water-soluble form of vitamin C that functions on the skin as a potent antioxidant in brightening uneven and tired skin-tone and keeping the skin glowy and clean. 

Relatively small amounts of sodium ascorbyl phosphate (at least 5%) are sufficient for regulating acne-prone skin and skin prone to sebum hyper-production. In that sense, products based on this vitamin C derivative prevent the development of new acne on a microbiological level and at the same time treat the remnants of once-present acne.

Besides that, SAP has been proven to reduce oxidative stress of the skin caused by environmental factors such as UV radiation and environmental pollution, leading to microscopic damage to the skin which accumulates over time. This accumulated skin damage, as well as reduced collagen production, we notice as signs of aging. As an antioxidant, SAP acts precisely against this oxidative stress and it is estimated that in this role it is effective even in very low concentrations (0.2% to 2%). In addition to being an antioxidant, SAP also acts as a melanin-inhibitor making it a very important skincare component targeted against hormonally induced hyperpigmentation and post-inflammatory pigmentation, while for a lightening effect an adequate concentration in a product is above 3%. 

It is important to point out that SAP is gentle enough even for very sensitive skin. Further, vitamin C is even recommended for skin with impaired capillary function.

Skintegra Superba C serum

Superba C serum contains 10% sodium ascorbyl phosphate, which makes it extremely effective on all skin types faced with first signs of aging (fine lines and wrinkles), skin texture problems, pigmentation marks, uneven and tired-looking skin tone and acne. 

Due to its stability in a pH 6 to 6.5 medium, our potent SAP-containing serum can be combined with other active components such as niacinamide and bakuchiol. Due to its stability, SAP doesn’t make this skin sensitive to sun, so it is recommended to use Superba C in the morning, before your usual sunscreen. This serum boosts the photo-protective effect of a sunscreen, making this combination of products ideal for uneven skin tones, but also for preventing early signs of skin aging.
