Know Your Ingredients: L-Ascorbic Acid (Vitamin C)

Posted By Vien
L-ascorbic acid, also known as Vitamin C, is a type of water-soluble vitamin that plays an essential role in the growth and repair of tissues. It's found in fruits and vegetables (as well as other sources), but it can also be produced synthetically to be used in skin care products like serums and moisturizers because of its proven anti-aging benefits.

What is it?
L-ascorbic acid is a vitamin C form that has anti-aging and anti-inflammatory properties. It's also a powerful antioxidant that can help neutralize free radicals, preventing them from damaging skin cells and causing signs of aging, such as wrinkles and age spots.

While it's possible to get your daily dose of vitamin C from food sources like citrus fruits and leafy greens, L-ascorbic acid offers the most effective way to reap its benefits when applied directly to your skin.

How does it work?

As a powerful antioxidant, L-ascorbic acid works to reduce the appearance of fine lines and wrinkles. It also helps to improve skin elasticity and tone, hydration levels, and radiance. This is all thanks to it reducing oxidative stress on the skin by neutralizing free radicals, which can damage cells and lead them to age faster than they should.

Where does it come from?

L-ascorbic acid is a naturally occurring substance found in many fruits and vegetables. It can be synthesized in the lab, and it's used in food, cosmetics, and medicine.

How to Use the Products with L-Ascorbic Acid?

To get the most out of your L-ascorbic acid product, we recommend the following steps:

1. Cleanse your face with a gentle cleanser.
2. Pat your face dry with a clean towel and wait until it is completely dry before applying any serums or moisturizers.
3. Apply a small amount of serum to your fingertips and gently pat it on your skin in circular motions until fully absorbed.

Pros and Cons of L-Ascorbic Acid
L-ascorbic acid is a powerful antioxidant that can help protect against free radical damage. Ascorbic acid is also the most effective form of vitamin C for fighting acne, as it has been shown to reduce sebum production and inflammation by inhibiting the secretion of arachidonic acid. But before you run out and buy some L-Ascorbic Acid, there are a few things you need to know:

  • Remember that L-ascorbic acid isn't always better than other forms of vitamin C—it depends on your skin type! There's a reason why people with oily skin should be wary about using this ingredient: It's oil soluble, which means it gets easily absorbed into your pores and can cause breakouts if you're not careful with how much product you apply or how often you use it (more on this later). If this is an issue for you, look for an alternative form like magnesium ascorbyl phosphate instead.
  • Avoid high concentrations at all costs unless absolutely necessary. Remember that high concentrations may leave an unpleasant residue when used in conjunction with other products containing AHAs or BHAs--and remember how important consistency is when trying new skincare products! If you have sensitive skin, pay attention to the pH level of your AHA or BHA products. The pH scale goes from 1-14; with 1 being highly acidic and 14 being highly alkaline. Ideally, you want something between 4.7-5.75—anything higher than this can cause irritation or even burns!
  • As we've already seen, too much L-ascorbic acid can cause redness and irritation—but did you know that lower pH levels will also increase absorption? This means products with higher concentrations might make your face flakier than usual; if so try switching brands until one works well enough without causing irritation.
  • It's not always easy to tell when a product is too strong for your skin type—so if you're unsure about whether or not something will work well with your personal needs, ask a dermatologist!

Also, certain medications (like antibiotics) tend to make the skin more sensitive. So does a reaction to an allergen such as dust mites or pet dander. These reactions can cause dryness and irritation in people with normal or oily skin types alike; however, the reaction tends to be worse in those with dry or sensitive complexions since they are already prone to having issues with their complexion anyway.

Once you've determined what causes your skin sensitivity and its severity ( mild, moderate, or severe ), then take steps to avoid those triggers as much as possible.

If you're doing everything right but still struggling with symptoms like redness or flaking, then consider using products without potential irritants.


In conclusion, L-ascorbic acid is a great ingredient that can help you keep your skin looking young and healthy. It can also protect you against sun damage and other environmental factors that can cause wrinkles. However, it’s important to remember that this ingredient only works when it’s used in combination with other antioxidants like vitamin E or ferulic acid—so make sure that anything you buy has plenty of these added!
