Unlocking the Radiance: The Marvels of Vitamin C Serum for Your Skin

Vitamin C serum in it’s most potent and stable form is a rare sight. Any vitamin C serum these days passes of just anything as vitamin C by bombarding you with pictures of oranges or lemons. They often miss out on the percentage of vitamin C, the skin type it needs to be used on or it’s actual functionality for the skin. However, after you receive clarity on what an intelligently crafted vitamin c20 facial serum can do, there’s no going back.

Ingredients Present in Vitamin C 20 Facial Serum

Before you prepare yourself for a long list of ingredients, let us burst your bubble. A lot of brands for vitamin C serum online or face cleanser online, face exfoliator or any other face serum online have been fooling you with their long list of ingredients that are somehow Ayurvedic or organic and chemical-based too. This is a major reason why even after following 1000s of skincare steps, the results are almost null and void.

In reality, a sensibly crafted vitamin C 20 facial serum hardly requires any scent or a long list of ingredients. Next time you’re out shopping for 20 vitamin C serum, check for 2 things: the accuracy of the vitamin C percentage and if it has EAA" or 3-O-Ethyl Ascorbic Acid. The presence of this ingredient in your vitamin C serum indicates that the face serum online that you ordered is of the most pure, stable and potent form. It is a water and oil soluble derivative vitamin C that further accentuates its primary benefits: skin brightening, dark spot and pigmentation reduction, reduction in inflammation, prevention of wrinkles and fine lines and skin hydration with moisture retention. The 20% pure vitamin C in the 20 vitamin C serum ensures that your skin receives the most accurate and adequate amount.

  • Not storing it in a cool dark place. Exposure to sun or heat can oxidise the vitamin C Serum.

A: You will know if your vitamin C serum for dry skin is working from the visible improvement in your skin tone, skin brightening, and the appearance of a soft glow. There will be a reduction in blemishes, dark spots, and signs of ageing.
