Choosing a Vitamin C Serum

Vitamin C is a key constituent of any skincare regimen. As an antioxidant normally found in the skin, constant exposure to pollutants and UV rays diminishes our reserve of its protective strength. With the growing importance of using a topical vitamin C, how do we choose the perfect vitamin C serum?  

Advantages of Vitamin C Serum

Vitamin C in its topical form confers exceptional benefits for your skin’s health, especially as a facial serum. Vitamin C is a powerful antioxidant that brightens skin after hyperpigmentation and assists in collagen production, resulting in smoother, younger-looking skin. Humans cannot synthesize the antioxidant alone and must acquire it through diet. Studies show that topical applications of vitamin C serum provide the skin with progressive protection that lasts 72 hours. This reservoir supplies the skin with lasting antioxidant protection that cannot be rubbed or washed off.

The Ideal Vitamin C Serum

The ideal vitamin C serum needs to be formulated correctly and packaged properly to prevent an ineffective product. Details such as vitamin C concentration and acidity should be taken into consideration, as well as your skin type or any sensitivities. An effective vitamin C serum helps skin maintain an even, more youthful complexion.

Concentration

The ideal concentration of vitamin C is between 10% and 20%. Concentrations higher than 20% correlated with lower absorption through the skin. New users of vitamin C serum should consider using a lower concentration as higher levels may cause irritation to the skin. Lower concentrations are also recommended for the delicate skin around the eyes.

pH Levels

A lower pH level means a more acidic serum. A pH of 3.5 is recommended because this helps the vitamin C absorb into the skin. Any other pH levels in a serum’s formulation would not optimize measurable absorptions. Those with sensitive skin should consult a physician before using a product.

Color

Vitamin C serums should be light and clear throughout. A dark-yellowish or brown serum has already begun to oxidize, lowering its efficacy and signifying a new bottle must be bought.

Packaging

Vitamin C serums should be sold in dark, airtight bottles to prevent oxidation. Oxidation is caused by exposure to light, oxygen, and water and darkens the color of the serum. After every use, ensure that you’ve screwed on the cap tightly and always store in a cool, dark place. Refrigerating your product is the best way to extend its shelf life.

How to Use a Vitamin C Serum

A vitamin C serum should be applied once daily for a period of over several weeks; most users see results within 1 to 3 months. Clinical trials have shown that 15% topical vitamin C helped improve: the appearance of fine lines and wrinkles, discoloration and dark spots, brightening of skin, photoaging, and skin moisturization. Just a few drops should be applied to the face, neck, and chest, where UV rays can damage skin. Because vitamin C is naturally acidic, a moisturizer should be applied as a follow-up. It is important not to layer a vitamin C product with niacin (niacinamide); the combination can form a byproduct known as nicotinic acid which causes flushing and skin irritation.
