In The Spotlight: L-Ascorbic Acid - En Route Beauty

In The Spotlight: L-Ascorbic Acid

aka Vitamin C

It might be too soon to call it, but as far as the weather goes, autumn is upon us. While you ruminate on a wardrobe rotation from autumn dresses to juggling the idea of a leather jacket, when the weather drops, it’s the dry and dull skin for me.

If you’re suffering from newly formed sun spots, hyperpigmentation or a dull complexion but haven’t included Vitamin C into your skincare routine yet, now maybe just the time.

L-Ascorbic Acid also known as Vitamin C may not be for everyone—it wasn’t for me. To find out if it’s right for you and how you can incorporate it into your routine, please read on.

What is L-Ascorbic Acid?

 

In short, Vitamin C

Dermatologist, Dr. Shyamalar Gunatheesan explains “It is the biologically active form of Vitamin C.”

Jodie King, Skin Specialist and Founder of Skin Clinic Blyss adds, “L-Ascorbic Acid is a potent antioxidant to protect the skin from free radicals.”

How Does It Work?

 

L-Ascorbic Acid protects our skin from free radicals, prevents pigmentation, the breakdown of collagen and improves skin hydration.

  • Its high antioxidant properties neutralises free radicals and protects against photo-aging
  • Inhibits tyrosinase which is the enzyme that causes pigment production, resulting in brighter and even skin tone
  • Diminishes sun-spots and pigmentation
  • Accelerates the production of Hyaluronic Acid and Ceramides for skin hydration
  • Prevents enzymes from breaking down collagen and elastin for anti-ageing
  • It is the key factor in “The synthesis of Collagen 1 and 3,” tells Dr. Gunatheesan

What Skin Type Is It Best Suited To?

 

“All skin types tolerate the ester forms of L-Ascorbic Acid. Avoid using it on broken or sensitised skin,” explains Dr. Gunatheesan.

 L-Ascorbic Acid derivatives with higher PH and lower irritation:

  • Ascorbyl Tetraisopalmitate
  • Ascorbyl Glucoside

If you have sensitive skin or eczema, you may benefit from “Other forms of Vitamin C such as Tetrahexyldecyl Ascorbate,” however, if you suffer from rosacea and acne, you may flare up from using L-Ascorbic Acid, explains Jodie King.

When Do We Use It?

 

For best results, L-Ascorbic Acid should be used in the AM to fight against free radicals and to prevent photo-ageing.

If you’re new to Vitamin C, start with alternate days. If you have sensitive skin like me, I started out by using it 2-3 times a week and gradually increased from there.

How Do We Use It?

 

Do’s

  • Use in the AM
  • Use as a serum form “The most efficient at delivering the various L ascorbic acid esters into the dermis of the skin for collagen production,” says Dr. Gunatheesan

Don’ts

  • Use with Benzoyl Peroxide
  • Use with Retinol at the same time, use Retinol in the PM

L-Ascorbic Acid when in serums can be quick to oxidise and breakdown in the presence of heat, air and light. Hence the availability of pure crystal forms of Vitamin C which are activated by adding water. “This way the ingredient is always active for maximum activity on the target cells,” says Terri Vinson, Cosmetic Chemist and Founder of Synergie Skin.
