Happy Vitamin C Day!

As skincare professionals, we cannot emphasize enough the importance of this day dedicated to raising awareness about the wonders of Vitamin C for our skin.

Today, we’ll introduce you to two powerful forms of Vitamin C: L-ascorbic Acid and THD Ascorbate, which can significantly impact your skincare routine.

Let’s celebrate Vitamin C Day together by investing in our skin’s health and pampering it with the powerful effects of L-ascorbic acid and THD Ascorbate!

Vitamin C: The Skin’s Best Friend

Before we delve into the wonders of L-ascorbic Acid and THD Ascorbate, it’s essential to understand the incredible benefits of Vitamin C for our skin.

Collagen Synthesis

Vitamin C is fundamental in synthesizing collagen, the structural protein responsible for maintaining the strength and elasticity of our skin.

It helps to counteract the natural decline in collagen levels as we age, thereby preserving our skin’s youthful appearance.

Antioxidant Properties for Skin Protection

As a potent antioxidant, vitamin C helps neutralize harmful free radicals produced by environmental stressors such as UV rays and pollution.

It protects our skin from oxidative stress and damage, keeping it healthy, vibrant, and protected.

Brightening Effect

Vitamin C is widely known for its skin-brightening properties. It inhibits the production of melanin. This pigment is responsible for dark spots and uneven skin tone.

It also effectively lightens hyperpigmentation and evens the complexion, resulting in a more radiant and youthful appearance.

Encouraging Skin’s Natural Regeneration Process

Vitamin C not only protects our skin but also encourages its natural regeneration process. By stimulating cell turnover and promoting the shedding of dead skin cells, it reveals a fresh, healthy layer of skin underneath. This rejuvenating effect produces a smoother, clearer, and more luminous complexion.

L-Ascorbic Acid

L-ascorbic Acid is the purest and most biologically active form of Vitamin C, making it highly effective in delivering its skin-loving benefits. Its potent nature allows it to deliver visible results, ensuring you experience Vitamin C’s full potential in your skincare routine.

One of the reasons L-ascorbic Acid is so effective is its ability to be easily absorbed by the skin. Its low molecular weight allows it to penetrate the skin’s outer layer, reaching the deeper layers where collagen synthesis and other vital processes occur. This easy absorption translates to better efficacy and more noticeable results.


  • Stimulates collagen production: L-ascorbic Acid is known for boosting collagen production, helping maintain skin firmness and elasticity.
  • Reduces wrinkles and fine lines: By promoting collagen synthesis, L-ascorbic Acid minimizes the appearance of wrinkles and fine lines, giving your skin a smoother and more youthful appearance.
  • Protects skin from free radical damage: L-ascorbic Acid’s potent antioxidant properties neutralize free radicals and protect your skin from the harmful effects of environmental stressors, reducing oxidative damage from free radicals, UVA, UVB, ozone exposure and diesel exhaust by 41%.
  • Evens skin tone: L-ascorbic Acid inhibits melanin synthesis, brightening dark spots and hyperpigmentation for a more even and radiant complexion.

Proper Usage

Typically, 10-20% L-ascorbic acid concentration is recommended for optimal results. Start with a lower concentration and gradually increase it as your skin becomes accustomed to the ingredient.

Apply L-ascorbic acid serum on clean, dry skin in the morning before moisturizer and sunscreen to ensure maximum absorption and protection throughout the day.

THD Ascorbate

THD Ascorbate is a stable and oil-soluble form of Vitamin C, making it an excellent option for those concerned about the stability issues often associated with Vitamin C products. Its oil-soluble nature allows it to blend seamlessly with other oil-based skincare products, ensuring a smooth application and better absorption.

Unlike L-ascorbic Acid, which is water-soluble, THD Ascorbate‘s oil-soluble property enables it to penetrate the skin’s lipid barrier more effectively. This deep penetration allows it to reach the lower layers of the skin, where collagen synthesis and other vital processes take place, resulting in more significant benefits.


  • Enhances collagen synthesis: THD Ascorbate’s ability to reach deeper layers of the skin boosts collagen production, improving skin firmness and elasticity.
  • Improves skin elasticity: By stimulating collagen synthesis, THD Ascorbate helps to enhance skin elasticity, making it more resistant to sagging and wrinkles.
  • Reduces the appearance of age spots: THD Ascorbate effectively targets age spots and hyperpigmentation, promoting a more even and radiant complexion.
  • Boosts skin’s barrier function: Because it reaches the deeper layers of the skin, THD Ascorbate helps to strengthen the skin’s barrier function, enhancing its ability to retain moisture and resist external stressors.

Revision C+ Correcting Complex 30%, a THD Ascorbate Vitamin C, with a synergistic blend of powerful antioxidants, is a top choice for adding vitamin c into your skincare routine.

Proper Usage

THD Ascorbate is a gentler alternative to L-ascorbic Acid, making it an ideal choice for sensitive skin or those new to Vitamin C.

To incorporate THD Ascorbate into your skincare routine, apply a serum or cream containing the ingredient in the morning, followed by a moisturizer and sunscreen.

As with L-ascorbic Acid, start with a lower concentration and increase gradually as your skin becomes accustomed to the ingredient.

Vitamin C: The Perfect Pairings

When maximizing the benefits of Vitamin C, sometimes two (or more) are better than one!

By thoughtfully pairing Vitamin C with complementary ingredients, you can create a synergistic effect that amplifies the overall benefits for your skin. These combinations boost the efficacy of Vitamin C and offer additional advantages for a more comprehensive skincare approach.

Vitamin E: A Powerful Duo for Skin Protection

Vitamin E is a natural antioxidant that creates a formidable defense against environmental damage when combined with Vitamin C.

This dynamic duo works together to neutralize free radicals, reduce inflammation, and protect the skin from UV-induced damage. Vitamin E also helps stabilize Vitamin C, prolonging its shelf life and effectiveness.

Ferulic Acid: Enhancing Stability and Efficacy

Ferulic Acid is a plant-derived antioxidant that can significantly boost the stability and potency of Vitamin C.

When combined with Vitamin C, Ferulic Acid helps to enhance its antioxidant effects, providing an even greater level of protection against environmental stressors.

You’ll find this incredible combination with L-Ascorbic Acid in SkinCeutical CE Ferulic, another top choice for incorporating vitamin c into to your skincare routine.

Vitamin C in Your Daily Skincare Routine

Incorporating Vitamin C into your daily skin regimen can significantly affect your skin’s health and appearance. In this section, we’ll guide you through finding the right Vitamin C product for your skin type, when to apply it in your skincare routine, and tips for maximizing its benefits.

Finding the Right Vitamin C Product for Your Skin Type

With numerous Vitamin C products available on the market, choosing the one that best suits your skin type and needs is crucial.

A lightweight serum with L-ascorbic Acid may be ideal for oily or acne-prone skin.

For sensitive or dry skin, a gentler THD Ascorbate formulation may be more suitable.

Take the time to research products and read reviews to ensure you’re selecting a high-quality Vitamin C product.

When to Apply Vitamin C in Your Skincare Routine

For optimal results, applying Vitamin C at the right time in your skincare routine is essential.

Generally, it’s best to apply Vitamin C products in the morning after cleansing and toning but before moisturizing and applying sunscreen.

This process allows the Vitamin C to be absorbed effectively and provides protection against environmental stressors throughout the day.

Tips for Maximizing the Benefits of Vitamin C

To make the most of your Vitamin C products, keep these tips in mind:

  1. Store Vitamin C products in a cool, dark place to prevent oxidation and maintain potency.
  2. Use the appropriate concentration for your skin type and needs, starting with a lower concentration and gradually increasing as your skin adjusts.
  3. Be consistent with your Vitamin C application, as daily use will yield the best results.
  4. Always follow up with a broad-spectrum sunscreen to protect your skin from UV damage.

Remember the SPF!

Sun protection is a vital component of any skincare routine. Use a broad-spectrum sunscreen of 30 SPF or higher to guard against damaging UVA & UVB radiation and support the antioxidant benefits of Vitamin C.
