Pick the Best Vitamin C Serum
There are four main key to choose vitamin C serum
If you’ve want to know why you should invest in a vitamin C serum, take it from Manhattan Beach–based, board-certified dermatologist Ashley Magovern. “The good thing of the topical application of vitamin C on the skin are well-studied and quite strong. IF you ask me about my opinion, everyone should be applying vitamin C to the skin as part of a daily regimen,” she says. “A good topical treatment is highly underrated; it can make a incredible difference in the skin over time. My patients are often astounded by the difference they see in their skin with just adding a vitamin C serum.”
The Benefits of a Vitamin C Serum
Vitamin C is effective for many cellular and skin functions, in compliance with Dr. Magovern, including collagen synthesis, maintaining skin strength and integrity, wound healing and UV protection and free radical. “Vitamin C is a potent antioxidant that is naturally and normally found in the skin in high concentrate,” she explains. “As an antioxidant, it oxidizes (neutralizes) free radicals in the skin. Free radicals, which are formed from things like the sun, pollution, stress and smoking, damage the DNA of the cell, which can lead to premature aging and skin cancer. Vitamin C also reverses cell damage and boosts collagen production, which helps keep the skin firmer and younger, and even helps fade and prevent brown spots and pigmentation.”
How to Choose the Best Vitamin C Serum
Essential, indispensable vitamin C is to your skin care diet, not all vitamin C serums are created equal. There are four main factors your need to consider when looking for a vitamin C serum According by Dr. Magovern,
Form of Vitamin C.
Vitamin C comes in different forms—L-ascorbic acid, tetrahexyldecyl ascorbate, ascorbyl palmitate and sodium ascorbyl phosphate, among others—but not all of them are equal in terms of stability and absorption rate. “As with all active ingredients in skin care and critical with vitamin C, it is essential that it is well formulated and has good penetration and bioavailability,” note Dr. Magovern. “that is to say, it is able to get to where it needs to go and do what it’s supposed to do. According to the market place most of serums contain vitamin C in the form of L-ascorbic acid, but some experts prefer the ester form, called tetrahexyldecyl ascorbate, which they believe can be more effective.”
Concentration.Concentration is basically the strength of the acid, explains Dr. Magovern. “At least concentration with10% L-ascorbic acid is recommended; at the same time, you will find some products on the market that offer 15 or 20%. The concentration is key point, but the best vitamin C serums combine other antioxidants and boosters like vitamin E and ferulic acid, which probably adds more value than just increasing the concentration alone.”
As long as vitamin C alone has proven benefits, studies show that combining it with equally potent ingredients can heighten its efficacy. Dr. Magovern implies: “There is a good deal of evidence showing that combining vitamin C with vitamin E and ferulic acid makes for lot better potent antioxidant with added benefits. Vitamin E itself acts as an antioxidant and also improves the function of vitamin C. It also helps to maintain the skin obstacle. Ferulic acid improves both vitamin C and vitamin E. Also glutathione is another antioxidant that works synergistically with vitamin C and is one to keep your eye on.”
“A great formulation can be costly to make to ensure proper stability and bioavailability, two of the essential factors when creating a vitamin C product,” says Dr. Magovern. Addition, she also notes that the price of a product isn’t always an indication of quality. “Expensive doesn’t always mean better. Some of the most expensive products on the market may actually have an inferior formulation or may not have as much research to support the product. In conclusion, I would stick with good advice from dermatologists and other skin care experts when choosing products.”
How to Use a Vitamin C Serum for Best Results
There are different ideas and theories way that how and when to use a vitamin C serum. Some connoisseurs believe that vitamin C should be applied at night in order to help skin repair itself while other sleep-restorative functions are taking place. Some believe that it should be applied during the day in order to help fight off free-radical damage as it accumulates through the day. For Dr. Magovern, the key is not witch time of day you apply it; main thing is that you remember to use it.
Amount of times? Dr. Magovern reveals that you may not need to use it every day. “The receptors for vitamin C get saturated and it may not need to be applied every day,” she says. “You may not get added benefit from daily application. I would recommend application at least every 48 to 72 hours.”
Something else of importance to note is how you store your bottles to ensure potency. “Vitamin C bottles should keeping in a cool, dark place is best. You’ll notice that formulas containing L-ascorbic acid will (and should) come in a brown or amber bottle, which is important to maintain stability,” she explains. “If your serum starts to turn brown, it’s probably time to get a new one, and it should probably be replaced at least every six months. On the other hand, if you are using it properly and being compliant with your skin care regimen, your bottle shouldn’t last long.”
Precautions to Note
If you have sensitive skin and typically break out when trying a new product, you’d be happy to know that vitamin C is relatively safe for even the most sensitive skin, but that doesn’t mean you shouldn’t patch test your vitamin C just as you would any new product. “I am not aware of any harmful side effects to topical vitamin C, other than the occasional acne breakout or irritation that may come from a formulation that may not agree with your skin,” says Dr. Magovern. “If this happens, you could try another brand or formulation.”
