Frequently Asked Questions

Why is Vitamin C so important?
Vitamin C is a crucial component of skincare due to its numerous benefits for skin health. As a potent antioxidant, it helps protect the skin from harmful free radicals generated by factors like UV radiation and pollution. These radicals can cause premature aging, collagen breakdown, and dullness. Vitamin C also plays a crucial role in collagen synthesis, aiding in the maintenance of skin’s firmness and elasticity. Additionally, it can help fade hyperpigmentation and dark spots, promoting a more even skin tone. Including Vitamin C in your skincare routine can contribute to a brighter, youthful complexion and overall skin vitality. Read more about Vitamin C at Rejuvent Medical Spa.

Which form of Vitamin C is in this product?
Alastin C-Radical Defense Antioxidant Serum contains Sodium Ascorbate, a stable form of Vitamin C. Sodium Ascorbate is an antioxidant that helps defend the skin against free radicals, which are unstable molecules that can damage skin cells and accelerate the aging process. By neutralizing these free radicals, sodium ascorbate helps prevent oxidative stress and maintains skin health. Sodium Ascorbate is essential for collagen production, a protein that provides structure, firmness, and elasticity to the skin. Collagen production tends to decrease with age, leading to sagging and wrinkles. By promoting collagen synthesis, sodium ascorbate contributes to maintaining a more youthful appearance. This makes it beneficial for those with sensitive or inflamed skin conditions. and oxygen. Sodium Ascorbate can help reduce the appearance of hyperpigmentation, dark spots, and uneven skin tone. It inhibits the production of melanin, the pigment responsible for dark spots, leading to a more radiant and uniform complexion. Sodium Ascorbate has anti-inflammatory properties that can help soothe irritated skin and reduce redness.
