Reviews
Carla, Many medications can be and are applied topically by prescription. With that in mind, realize that this particular ingredient is wonderful but understand that this is indeed one of those that may create sensitivity with those already using topical hormones or just use sparingly and see how you respond. Sorry for the very late response..... ...»

Buy Sodium Ascorbyl Phosphate (SAP) For Skin Care

Vitamin C, or ascorbic acid, is one of nature’s most powerful antioxidants.As the natural aging process and environmental hazards increase the amount of free radicals in the skin, ascorbic acid and its derivatives can effectively neutralize these damaging agents and prevent further damage.Ascorbic acid has been shown to increase the synthesis of collagen in the skin to reduce the appearance of wrinkles and to block the melanin synthesis pathway, reducing age spots and lightening skin.Unfortunately, ascorbic acid is not stable in aqueous solutions and is quickly degraded.The hydrophilic ascorbic acid derivative sodium ascorbyl phosphate is significantly more shelf-stable in solutions and, as it is converted to ascorbic acid in skin, retains all of the skin-benefitting aspects of vitamin C.Therefore sodium ascorbyl phosphate is the ideal choice for anti-aging emulsion creams.

Key benefits of Sodium Ascorbyl Phosphate in skin care:

  • Anti-acne [7]  [8]
  • Antioxidant [3] [4] [6] [9] [10]
  • Increase skin elasticity [1] [4]
  • Reduce fine lines and wrinkles [1] [4]
  • Stimulate collagen production [1] [4]
  • Sun damage protection [9] [10]
  • Sun damage repair [9] [10]
  • Lightening and brightening [12]
  • Treat hyperpigmentation [12]

Sodium Ascorbyl Phosphate (SAP)

About Sodium Ascorbyl Phosphate (SAP) in DIY Skin Care

Ascorbic acid, or vitamin C, is a water-soluble vitamin and a naturally occurring powerful antioxidant.Ascorbic acid is typically obtained primarily from the diet and is necessary for multiple enzymatic reactions, including collagen synthesis [1].Aging and environmental hazards, such as smoking or sunlight, reduce collagen content in skin while increasing levels of damaging free radicals.Topical application of ascorbic acid has been demonstrated to reverse these signs of aging and to improve the elasticity and appearance of the skin [1-4].Further, ascorbic acid can reduce the appearance of hyperpigmentation, or age spots, due to its antioxidant effects [5,6].Other benefits of ascorbic acid on the skin include antibacterial effects which successfully reduced the appearance of acne in several clinical trials [7,8] and use as a sunscreen to prevent damage from free radicals formed by UV light [9,10].For a complete description of the benefits of ascorbic acid, please refer to the literature review on our site here: https://www.bulkactives.com/vitamins/vitamin-c-and-its-derivatives

A major issue with using ascorbic acid is that in its natural form in aqueous solutions it is quickly ionized and prone to oxidative degradation.To circumvent this drawback much research has recently focused on derivatives of ascorbic acid which are more shelf-stable in solution and can efficiently penetrate the skin while still retaining all of the skin-benefitting aspects of the parent compound.One such derivative is sodium ascorbyl phosphate, a hydrophilic compound which can be incorporated into a microemulsion and is converted to ascorbic acid after permeation into the skin.A study investigating optimal formulations of sodium ascorbyl phosphate for topical application determined that for water/oil microemulsions 4.00% [m/m) colloidal silica yielded the ideal gel-like consistency whereas 0.50% [m/m) xanthan gum was ideal for oil/water microemulsions.Incorporation of the sodium ascorbyl phosphate during the internal aqueous phase demonstrated sustained release profiles, indicating that the benefits conferred by this compound may increase over time [11].Indeed, when sodium ascorbyl phosphate microemulsions were applied to skin in a porcine model of dermal application the amount of free radicals was significantly reduced in both a concentration- and time-dependent manner [9].

Multiple studies on the effects of topical application of sodium ascorbyl phosphate have determined that the dermal effects of sodium ascorbyl phosphate are as or more efficacious than the parent compound.In a cell culture model of sunburn, pretreatment with sodium ascorbyl phosphate prevented the condensation or loss of nuclei typically associated with UV-irradiation, marking sodium ascorbyl phosphate as a promising agent for use in sunscreens.Not only does this decrease the physical assault [burn) associated with sun exposure but also attenuates the mutagenicity of UV irradiation [10].In a model in which sodium ascorbyl phosphate was applied to human excised skin for 48 hours increases in collagen type I and III as well as cytokeratin were significant, underscoring the potential for sodium ascorbyl phosphate in anti-aging formulations [4].Due to increased penetration into the skin compared to the parent compound sodium ascorbyl phosphate also can better neutralize products of the melanin synthesis pathway to significantly reduce the appearance of age spots and lighten and brighten skin [12].Finally, several clinical studies have demonstrated that sodium ascorbyl phosphate is a potent antibacterial agent, improving acne vulgaris [7,8]. In one clinical study testing topical application of sodium ascorbyl phosphate over twelve weeks earned a qualitative score of “excellent” in improvement of acne as reported by 76.9% of trial participants, outperforming a leading acne treatment by a wide margin [7].

  • Sodium Ascorbyl Phosphate (SAP) may discolor in formulations with a pH below 6, so is best used in products with a final formulation pH between 6.0 - 7.0.
  • If you're having trouble dissolving Sodium Ascorbyl Phosphate (SAP) in water, warming the solution to about 40°C (104°F) will help.
  • It is essential that you do NOT add the powders to the water at once, sticky lumps WILL form. It is best to sprinkle tiny amounts at a time, mix that, and then add more.

Sodium Ascorbyl Phosphate is a crystalline solid that is sensitive to heat, moisture, low pH values and heavy metals.
In the production of cosmetic care products, it is recommended to add Sodium Ascorbyl Phosphate to formulations at a low temperature ( <40°C).
It can be exposed to higher temperatures up to 80°C, but only for a short time.
The product is most stable above pH 6.5. It is recommended to use a buffer system and to add a chelating agent.
Finished formulations should be stored at a temperature below 25°C.
