Vitamin C for Skin Health: Your Complete Guide

Are you concerned about premature ageing?

Do you look in the mirror and see uneven skin tone and dark spots?

Then, you could do much worse than introducing vitamin C into your routine.

A potent dullness-eliminating, wrinkle-preventing, collagen-boosting, brightening ingredient.

And if that’s enough, it’s an antioxidant powerhouse that can help prevent premature ageing.

Blimey, with such a laundry list of benefits, couldn’t we all do with some vitamin C love in our lives?

Then, join us to learn more about this holy grail ingredient.

The power of Vitamin C in skincare

Vitamin C is a naturally occurring compound in your skin that resides in the outer layer, with a smaller amount in the deeper dermal layers.

Its significance in skin biology is well-documented (1).

At its core, Vitamin C operates as a water-soluble antioxidant, a remarkable compound that has several benefits:

  • it has been shown to stimulate collagen synthesis
  • foster the formation of the skin’s protective barrier
  • expedite wound healing
  • improve hyperpigmentation, those stubborn dark spots
  • lighten and brighten, enhancing luminosity and skin tone

You’re likely familiar with oxidative stress, free radicals, and the adverse effects of photoaging.

These factors can cause your skin to age prematurely, but once again, vitamin C is a powerful antioxidant that stops these troublesome molecules in their tracks.

Astonishing benefits of ascorbic acid

In the realm of cosmetics, numerous Vitamin C derivatives exist, including ascorbyl palmitate, retinyl ascorbate, tetrahexyldecyl ascorbate, sodium ascorbyl phosphate, and magnesium ascorbyl phosphate, yet none quite match the prowess of L-ascorbic acid.

It is the purest and most biologically available. It has also been extensively researched, which is why it is featured in our C+ Vitamin Complex. Let’s look at some of the benefits of this potent ingredient:

#1 Found in the Epidermal Layer

L-ascorbic acid gracefully resides in every layer of your outer layer of skin (technically, there are five), where it plays a pivotal role in stimulating collagen synthesis and facilitating the creation of essential barrier lipids.

#2 Potent Antioxidant

It boasts formidable antioxidant properties, functioning as a vigilant guardian against the perilous assault of damaging free radicals, which can potentially hasten ageing in your skin.

#3 UV Radiation Shield

L-ascorbic acid is a formidable shield against the harmful effects of UV rays. When combined with sunscreens, it can enhance their efficacy by up to 30%.

#4 Collagen and Elastin Support

Vitamin C promotes the production of collagen and elastin fibres, giving your skin important structural support and snapback associated with youthful skin.

#6 Preservation of Collagen Density

L-ascorbic acid combats the enzymes responsible for collagen depletion, thereby preserving skin density and bolstering resilience—key factors in maintaining a youthful complexion.

#7 Melanin Control

It reduces melanin oxidation—the molecule accountable for dark spots. Furthermore, it moderates the production of tyrosinase, the enzyme that triggers melanin production. Thus making it the perfect ingredient to target dark spots.

#8 Enhanced Microcirculation

This remarkable acid elevates cutaneous microcirculation; in layperson’s terms, it transports essential nutrients to the outer layers of your skin, culminating in that coveted, radiant glow.

Important points to consider 

As mentioned above, it’s important to understand that not all Vitamin C products are cut from the same cloth in the skincare world.

The specific type of Vitamin C, its concentration, and the inclusion of complementary ingredients to stabilise it are all crucial factors that must be considered.

To maximise the benefits of Vitamin C on your skin, a minimum concentration of 10% or higher is recommended.

Maintaining a pH of approximately 3.5 ensures optimal penetration of Ascorbic Acid into your skin’s horny layer (yep, you read that right, there is such a layer!).

Its naturally low pH effectively “softens the glue” between skin cells, enabling deeper penetration into the layers below.

Nonetheless, it’s essential to acknowledge the delicate nature of L-ascorbic acid.

Especially when present in skincare products with water, it tends to lose its effectiveness swiftly.

To harness its potential effectively, several conditions must be met during formulation:

  • The product must maintain a slightly acidic pH, ideally around 3.5 or lower.
  • The concentration of ascorbic acids should range from at least 10% and can extend to 30% for optimal results.
  • Supplementary ingredients like vitamin E and ferulic acid aid in stabilising ascorbic acid, offering enhanced protection for your skin.
  • Choose packaging that shields against excessive light and air exposure, avoiding clear glass containers.
  • Lastly, ensure timely usage, as ascorbic acid loses its potency over time, even with stabilisation, and should be used within six months of opening.

When searching for a Vitamin C skincare product, we recommend considering all of these factors to ensure its freshness and unleash the full potential of this remarkable ingredient.

Our ascorbic acid products

  • C+ Ascorbic Acid skin shot: Our Vitamin C serum is fortified with the dynamic duo of ascorbic acid and ferulic acid, creating a formidable antioxidant powerhouse. Ascorbic acid works in synergy with ferulic acid to extend the duration of its shelf life and antioxidant potency. Additionally, we add vitamin E into the mix to boost the antioxidant synergy even further—a combination that has been scientifically proven to neutralise free radicals on the skin.
  • Glow (Coming Soon): Our speciality organic oil takes centre stage, featuring a vitamin C liposomal ingredient known as tetrahexyldecyl ascorbate. This is a stabilised, water-free serum where acid crystals have been meticulously micronised and encased within an oil ‘envelope. It is an innovative formula that shields tetrahexyldecyl ascorbate from oxidation, ensuring its potency remains intact.

A Gentle approach to application

Once you apply your ascorbic acid product, avoid other acid-based products, as they can trigger oxidation, especially when layered on top of ascorbic acid.

Remember, it works on your skin like a protective shield during the day, fortifying it against the onslaught of free radicals and enhancing the efficacy of your sunscreen.

Therefore, morning application is recommended to safeguard your skin from damaging environmental pollutants.

Incorporating Vitamin C into your evening routine can contribute to reversing the day’s toll on your skin, orchestrating a rejuvenating symphony while you slumber.

But if you use retinol or acid-based products, use those at night instead of at the opposite time of day from your vitamin C.

Finally, we urge you to scrutinise the quality of your chosen Vitamin C formula. It is water-soluble and prone to rapid oxidation in water-based formulations.

This process transforms it into dehydroascorbic acid, which produces an oxidised version, so ensure it does not have an orange or brown hue.

To conclude. The naked truth

In this article, we have discussed the holy grail vitamin C derivative, ascorbic acid, which has many benefits when it comes to your skin’s health.

It is a potent antioxidant that stimulates collagen synthesis, which is important in a world filled with oxidative stress and free radicals that can cause premature skin ageing.

Ascorbic acid also promotes skin barrier formation, expedites wound healing, and alleviates skin discolouration, effectively combating hyperpigmentation.

However, handling ascorbic acid with care is crucial, as it can lose its effectiveness very quickly, especially in water-based formulations, so choose products with supplementary ingredients, like vitamin E and ferulic acid.

These ingredients help preserve ascorbic acid while boosting its full potential as a remarkable antioxidant.

Your skin’s journey to radiance and resilience does begin with this holy grail vitamin.
