Sodium Ascorbyl Phosphate (Ingredient Explained + Products)

Vitamin C brightens dull skin, fades dark spots, and boosts collagen production to reduce fine lines.

Antioxidants inhibit oxidation, or a chemical reaction that leads to cell-damage and are found to correct signs of aging, brighten skin tone, and some antioxidants help stimulate collagen.

Some ingredients are used to help combat dullness by promoting smoother, more radiant skin.

Pores are tiny openings in the skin that release sweat and oil. Everyone has them, and it's completely normal for them to be visible. While factors like excess oil, acne, sun damage, and even genetics can make pores appear larger, these ingredients may help minimize their appearance. Just keep in mind: you can't erase pores entirely, and that's okay!

Some ingredients are commonly used to help calm visible redness and soothe irritated skin. While they can be effective for many people, results can vary depending on the cause of redness and individual skin sensitivity. If redness persists or worsens, it's best to check with a dermatologist.

Good for Scar Healing

Some ingredients are commonly used to support the skin's natural healing process and improve the appearance of scars over time. While results can vary, they may help with texture, discoloration, and overall skin recovery.

The most common cause of textured skin is a build up of dead skin cells. The easiest way to get rid of textured skin is to exfoliate and give your skin the proper nutrients.

Sodium Ascorbyl Phosphate (SAP) is a water-soluble form of Vitamin C. It is the salt of ascorbic acid.

This ingredient is commonly used in skincare because it's more formulation-stable while still offering the same benefits as pure ascorbic acid. Ascorbic acid is notorious for breaking down when exposed to sunlight and oxygen whereas SAP has been shown to be more stable.

Studies show SAP has anti-acne and antioxidant benefits. One study found 5% of SAP lotion to be an effective ingredient for treating acne vulgaris. This is because research shows that SAP may help control acne by reducing acne-causing bacteria and slowing the oxidation of skin oils caused by UV exposure.

In addition to acne, vitamin C is important for skin structure. Lab studies suggest SAP may support collagen production in skin cells, making it a great ingredient in anti-aging routines.

Vitamin C has many benefits: it helps reduce redness, improve skin texture, fade the appearance of dark spots, and brighten the skin.
