Experts say the best vitamin C serum should have a concentration of 10–20% . A person should choose a product that its ingredients are compatible with their skin type: Dry skin: Look for products containing hyaluronic acid, as it moisturizes the skin.
For a vitamin C serum to be effective, it should ideally have a concentration between eight and 20 percent. The higher the concentration, the more potent it is. Serums with vitamin C concentrations below eight percent are ineffective, while above 20 percent, their effectiveness tapers off.
From the safety point of view Vitamin C Serum is ideally safe, various products can be use along-with 10% or 20% Vitamin C Serum depending on the skin type. We can use vitamin C serum alongside other skin care products. However, people should be careful about combinations of vitamin C and: retinol.

Can You Use Hyaluronic Acid and Vitamin C Together?

Best overall vitamin-C serum
Four of our dermatologists recommend SkinCeuticals C E Ferulic, which they (and our editors) hail as the gold-standard vitamin-C serum and is suitable for all skin types.
L-Ascorbic Acid (L-AA)
This is vitamin C in its purest form - the gold standard of vitamin C. Ascorbic acid is the most biologically active of all the derivatives, making it the strongest and most effective in terms of antioxidant abilities, reducing pigmentation, and boosting collagen production.
The term to look for is ascorbic acid (also known as L-ascorbic acid), which is the most stable and effective form of vitamin C in skin care. That said, all three dermatologists agree that the best type of vitamin C skin-care product to use is serum, because "serums are more effective than creams or toners," says Dr.
The first thing to know is that when present in something like a serum, it should be colorless—and it should be stored in a dark place in a dark bottle. “When it's exposed to light, it becomes unstable,” she explains, which you can actually see take place because the product will turn yellow.

So, should I use vitamin C or retinol for wrinkles? Well, when it comes right down to it, the choice is really in what you're looking to do for your skin. While vitamin C is incredible for the skin because of its ability to help brighten and improve hyperpigmentation, the best active ingredient for wrinkles is retinol.
Salicylic acid and vitamin C are both effective products on their own but, when combined, they can be even more beneficial. Whether you're looking to brighten your skin, reduce the likelihood of blemishes or just help slow down the skin's natural aging process, these ingredients may be just what you're looking for.
It's best to apply Vitamin C before Retinol, as Vitamin C has a lower pH than Retinol. Once your skin absorbs the Vitamin C serum, your skin will return to its regular pH levels after 30 minutes or so. (You want your skin to return to its normal pH levels so vitamin C doesn't lower the pH of retinol.)
Good (Skin) Days C's The Day Serum
Vitamin C moisturizers are also becoming more common, Dr. Lamb says, and you'd want to use those at the end of your skin-care routine. And if you're wondering if you can use vitamin C every day, the answer is yes.
Obagi-C® Rx System - Normal to Dry

For those with sensitive, reactive skin, certain forms of vitamin C can be shockingly irritating, leading to dryness, peeling, and redness. But you shouldn't bin your vitamin C serums or moisturizers right after reading that.
If you are applying a Vitamin C serum and hyaluronic acid separately, it's suggested that you apply the Vitamin C first, and then add the hyaluronic acid afterward in order to help fortify the skin barrier and lock in the moisture.
A tell-tale sign of vitamin c over-use can be increased blackheads or a development of blackheads. General skin irritation and breakouts can also occur if you are using your vitamin c too much or too often. We recommend using your serum 1-2 times a day and 2-4 drops is all that is needed.
Many people also take supplements to ensure they're getting enough of it. This has raised concerns over the likelihood of an accidental overdose. Too much vitamin C can cause undesirable effects. However, a severe overdose is rare and unlikely.
