History

Vitamin C is often used in the form of ascorbic acid topically. This potent antioxidant plays a crucial role in collagen production and synthesis. It also protects skin against environmental damage caused by free radicals, and you can find this widely in pair with other trending ingredients.

Early Recognition

The benefit of vitamin C on the skin was not recognized until the early 20th century. Its unstable nature to air or light posed a significant challenge for its use in skincare formulations.

Stabilization Breakthroughs

The 1980s and 1990s marked a significant advancement in vitamin C. Researchers began to develop multiple forms of vitamin C such as L-ascorbic acid, magnesium ascorbyl phosphate, and scorbyl palmitate. The focus was often on improving the stability of skincare products.

Innovations and Formulations

The 2000s saw a surge in the innovation of vitamin C formulas. Serums, creams, and other skincare products with various concentrations of vitamin C aimed to maximize its benefits that work across all skin types, and concerns.

Recent Developments

Today, we continue to witness the evolution of skincare incorporating vitamin C, with the advancements in encapsulation techniques, the combination of vitamin C with other antioxidants, and topical ingredients such as vitamin E and ferulic acid.

Molecular Elements

Topical vitamin C, primarily known for its pure form as L-ascorbic acid, is a potent antioxidant that interacts with the skin at a molecular level to offer a range of benefits topically, and they are effective at anti-aging, skin brightening, and UV protection.

Antioxidant Protection

Vitamin C helps electrons to neutralize reactive oxygen species (ROS) that often come from UV radiation, pollution, and other environmental stressors, and there are some other benefits that this topical ingredient offers:

1. Antioxidant Activity: As mentioned, its antioxidant properties neutralize environmental stressors.
2. Collagen Synthesis: Vitamin C is a necessary cofactor for the enzymes prolyl and lysyl hydroxylase. These involve the synthesis of collagen.
3. Inhibition of Melanogenesis: This enzyme is involved in creating melanin, and pigment on the skin, contributing to changing the skin color. As a result, vitamin C can help lighten hyperpigmentation, fade dark spots, and even out skin tone.
4. Enhancing Skin Barrier: Vitamin C can be beneficial to the skin barrier function by promoting the production of barrier lipids, decreasing water loss, and improving skin hydration. This effect helps maintain healthy, resilient skin capable of protecting itself against environmental aggressors.
5. Photoprotection: While not a substitute for sunscreen, vitamin C provides a layer of protection against UV damage by neutralizing free radicals, and reducing inflammation. As a result, it prevents aging and reduces the risk of sunburn and skin cancer.
6. Synergistic Effects: When combined with other antioxidants like vitamin E and ferulic acid, vitamin C stability and efficacy significantly improve. This synergy boosts its antioxidant power and increases its sun-protective properties.

Effects

Antioxidant Protection

Vitamin C is a powerful antioxidant that neutralizes free radicals. This action helps the skin from oxidative stresses and contributes to preventing premature aging, or skin damage.

Brightening and Even Skin Tone

It inhibits melanin production in the skin, which can help fade hyperpigmentation, dark spots, and melasma, leading to a more even skin tone and brighter complexion.

It inhibits melanin production in the skin. Hyperpigmentation can be preventable with vitamin C. If you have dark spots or melasma often caused by hyperpigmentation, vitamin C can help even skin tones, and enhance the overall look of your skin.

Collagen Production

Vitamin C is essential for collagen production. It contributes to the skin’s firmness, and elasticity. Collagen can reduce the appearance of fine lines, and wrinkles, promoting a youthful skin appearance, and much more.

Reduces Under-Eye Circles

Its skin-brightening properties can help lighten under-eye circles, often characterized by shaded, and dark areas.

Hydrates the Skin

Vitamin C can decrease skin water loss, allowing your skin to retain much moisture. This is beneficial for improving your skin tone and maintaining overall skin hydration.

Reduces Redness and Inflammation

Its anti-inflammatory properties can help reduce redness and inflammation. This is especially beneficial for acne-prone, or oily skin with acne, or rosacea.

Enhances Sun Protection

While vitamin C doesn’t replace sunscreen, it can complement SPF effects with its antioxidant action. As an additional layer of defense, it protects against UV rays, and environmental stressors, preventing sun damage.

Improves Skin Texture

The collagen function dimishes as we age. However, vitamin C can help improve the overall texture of the skin by promoting collagen production on the skin.

Side Effects

Skin Irritation

The most common side effect of topical vitamin C is skin irritation. This can show up as redness, itching, or a stinging sensation upon application. This is more likely to happen with higher concentrations of vitamin C. If you have sensitive skin, start gradually with a low concentration.

Dryness and Flaking

Some people may experience dryness or flaking. It often subsides with a lower concentration of vitamin C. Using it less frequently can also help.

Allergic Reactions

Although very rare, some skin may have an allergic reaction to vitamin C or other formulas that contain vitamin C. It may show up as itching, redness, swelling, or blistering. If you experience these side effects, consult a dermatologist as it may do more harm.

Breakouts

In some cases, topical vitamin C can cause or worsen acne breakouts. This is not common but may be related to the formula of the product rather than the vitamin C itself.

Staining of the Skin

The serum with a high concentration of vitamin C may leave a yellow tint on skin, which is usually temporary, and can be washed off easily. However, this may be a concern for some users, especially with lighter skin tones.

Sensitivity to Sunlight

Vitamin C can be an additional layer of protection against UV rays, but some formulas may make the skin more sensitive to sunlight. However, its UV-protecting properties are often not potent enough, It’s essential to use a broad-spectrum sunscreen during the day.

Synergy

1. Vitamin E: Vitamin E (Tocopherol) is another powerful antioxidant. Combining with vitamin C enhances its ability to neutralize free radicals, and provides superior protection against environmental damage.
2. Ferulic Acid: Ferulic acid is often derived from plants, and when combined with vitamin C, or vitamin E, they work concurrently. Ferulic acid helps to stabilize vitamin C, making it remain much longer on the skin and boosting its sun protection properties.
3. Hyaluronic Acid: HA (Hyaluronic acid) is not an antioxidant, but it works well with vitamin C by hydrating skin. Vitamin C helps with the skin’s regeneration process, while hyaluronic acid locks it in moisture.
4. Retinol: Using retinol with vitamin C in combination is not recommended as it often causes skin irritation. However, you may use vitamin C in the morning routine, and retinol at night.
5. SPF: While not a skincare ingredient per se, sunscreen is essential with vitamin C. Vitamin C’s antioxidant properties help fight free radical damage from UV rays, and using the right SPF further protects the skin. This enhances vitamin’s efficacy in preventing sun damage.

Optimal pH Levels

pH Range for Stability

The optimal pH range of topical vitamin C is between 2.5 to 3.5. Vitamin C(L-ascorbic acid) maintain its stability at the range, and is more likely to remain in its active form. This is essential for its antioxidant properties, collagen synthesis, and its ability to reduce hyperpigmentation.

Skin Absorption

The skin’s natural pH is slightly acidic, typically around 4.7 to 5.75. The vitamin C formula closer to its optimal range ensures better absorption as it aligns more closely with the skin’s natural environment.

Avoid With

Benzoyl Peroxide

This acne-fighting ingredient can oxidize vitamin C, which makes it less effective. It can also counteract, and lead to skin irritation. It’s best to use them during the different times of the day.

Retinol (Vitamin A):

While some studies suggest that modern formulas allow retinol and vitamin C can enhance its effectiveness, it’s been advised to use vitamin C in the morning and retinol at night as it can potentially irritate especially on sensitive skin. Moreover, this combination can potentially cause stability issues as the acidic pH of vitamin C can destabilize retinol.

AHAs and BHAs

Alpha hydroxy acids such as glycolic acid and beta hydroxy acids such as salicylic acid can alter the pH of vitamin C, potentially reducing its antioxidant properties. While some formulas are designed to work together efficiently, using them separately is mostly recommended to prevent any potential irritation, and ensure the effects of vitamin C.

Misconceptions

All Vitamin C Products Are the Same

The efficacy of vitamin C can vary greatly depending on the form of vitamin C, concentration, and the formula's pH levels. L-aascorbic acid is the most potent form, but it can be also stable to the point where it easily oxidize if formulated improepry. Derivatives like magnesium ascorbyl phosphate and ascorbyl rtetraisopalmitate are more stable but may be less potent.

Higher Concentrations Are More Effective

The higher, the better. This concept is not always true with topical ingredients, especially for vitamin C. Concentrations above 20% do not increase its biological signiifcnace, and can cause skin irritation. For most skin types, a concentration between 10-20% is effective and well-tolerated.

Vitamin C Products Immediately Lose Potency Once Opened

While Vitamin C (especially L-ascorbic acid) is prone to oxidation, many formulas are designed to maintain it stability, and potency for longer periouds. To presever its effacy, store vitamin C products away from light and air, preferably in airtight, opaque packaging.

Vitamin C Is Only for Anti-Aging

Beyond its anti-aging properties, vitamin C. also helps with uneven skin tones, hyperpigmentation, and skin hydration. It's beneficial for a wide range of skin concerns, and types.

Vitamin C Can't Be Used With Certain Ingredients

This miscnception was once true. It was widely considered that vitamin C should not be used along with retinoids or niacinamides. However, recnet research, and formulas often focus on its compatbility to be used or even in the same product without reducing efficacy.
