Vitamin C is a potent antioxidant well-known for its brightening, anti-aging, and collagen-boosting properties. When it comes to selecting the best form of Vitamin C for skincare, the terms L-Ascorbic Acid and Ascorbic Acid are frequently used. This blog covers the distinctions between these two forms and will help you better understand which matches your skin.
Understanding the Basics: L-Ascorbic Acid and Ascorbic Acid
L-ascorbic acid is the most active and effective form of Vitamin C for skincare, delivering faster and more visible benefits than other forms of Ascorbic Acid. But it's unstable and could irritate skin that is already sensitive. Knowing the distinctions between these varieties enables you to select the ideal Vitamin C product for your unique skincare requirements and concerns.
What is L-Ascorbic Acid?
Ascorbic Acid is a generic word for Vitamin C in its natural form, which includes both L-Ascorbic Acid and its many molecular configurations. In skincare, ascorbic acid refers to Vitamin C and its derivatives. While L-Ascorbic Acid is the most effective and widely used form of vitamin C, other stable derivatives (such as Sodium Ascorbyl Phosphate) are classified as "Ascorbic Acid." These molecules are gentler and more stable, although they may not provide benefits as quickly as L-Ascorbic Acid.
What is Ascorbic Acid?
Ascorbic acid, or vitamin C, is a potent antioxidant required for many human activities. It is an essential vitamin that must be included in the diet. Fresh fruits and vegetables, particularly citrus fruits, are excellent sources. Vitamin C is required for normal bodily development and function and contributes significantly to immunological function. Most doctors recommend acquiring vitamin C from diet rather than pills. Fresh oranges and freshly squeezed orange juice are excellent sources.
Key Differences Between L-Ascorbic Acid and Ascorbic Acid
-
The purest and most potent form of vitamin C is L-ascorbic acid. The letter "L" refers to the specific molecular orientation needed to do its job in biological systems, including the skin. Ascorbic acid, on the other hand, includes all isomers of vitamin C, both active and inactive. There may be synthetic versions that are not as potent as L-ascorbic acid.
-
The most effective form of vitamin C for topical treatments is L-ascorbic acid because of its high bioavailability and quick skin absorption. It instantly affects the skin's natural functions. However, depending on the kind, ascorbic acid may not absorb as quickly or be as potent as L-ascorbic acid. The efficacy of different combinations varies greatly.
-
L-ascorbic acid is well-known for its exceptional skincare performance; it offers powerful antioxidant protection, stimulates collagen formation, and substantially brightens the skin. It is quite good at reducing pigmentation and improving overall skin texture. On the other side, while it is useful, it is frequently less efficient than L-Ascorbic Acid unless specially prepared for stability and absorption. It produces less pronounced results than L-ascorbic acid.
-
L-ascorbic acid is exceedingly unstable and prone to oxidation when exposed to light, air, and heat, resulting in a loss of efficacy. Proper formulation and packaging (such as dark glass bottles and sealed pumps) are essential. Ascorbic acid, on the other hand, is often more stable, particularly when converted into derivatives such as magnesium ascorbyl phosphate or sodium ascorbyl phosphate; however, these compounds frequently require conversion by the skin into the active form, lowering immediate potency.
-
To be stable and effective, L-ascorbic acid needs a pH of 2.5 to 3.5, which can irritate delicate skin, especially at higher dosages. However, depending on the formulation, ascorbic acid can exist in a range of pH settings, which makes it less irritating but possibly less effective.
-
L-ascorbic acid has a low pH and a high potency, which can produce stinging, redness, or irritation, especially in sensitive skin types or at high doses. Ascorbic acid, on the other hand, is less likely to irritate, particularly in its more stable derivative forms, making it better suited to delicate skin, but some efficacy may be lost.
The Science Behind Vitamin C: Benefits and Functions
One of the most impressive properties of vitamin C is its antioxidant activity, which protects the skin from a variety of damage. This is a closer look at how vitamin C's antioxidant properties protect your skin, including neutralizing free radicals, protecting against UV-induced damage, boosting the skin's natural defence mechanisms, reducing inflammation, slowing photoaging, enhancing skin repair and healing, preventing degradation, and improving skin barrier function.
Antioxidant Properties: Protecting Your Skin from Damage
The antioxidant properties of vitamin C shield the skin from many sorts of damage, making it one of the most significant benefits of this vitamin. Here's a closer look at how vitamin C's antioxidant qualities shield your skin from UV rays, neutralize free radicals, strengthen the skin's defences against damage, and redness, delay photoaging, improve skin repair and healing, stop degradation, and enhance skin barrier function.
Collagen Production: Enhancing Skin Strength and Elasticity
-
Role of Collagen: The most common protein in the skin is collagen, which makes up around 70% of its dry weight. It establishes a network of support that preserves the elasticity, hardness, and structure of the skin.
-
Collagen Synthesis: It functions as a cofactor for the enzymes prolyl hydroxylase and lysyl hydroxylase, vitamin C is essential for the production of collagen. These enzymes give collagen its strength by stabilizing the collagen molecule and enabling cross-linking.
-
Protecting collagen: Vitamin C's antioxidant properties protect existing collagen against free radical damage caused by UV radiation and environmental pollutants. This protection helps to preserve the collagen that currently exists in the skin.
-
Supporting Wound Healing: Collagen is essential for wound healing because it forms the structural basis for new tissue. Vitamin C speeds up the healing process by boosting collagen synthesis at the wound site.
-
Improving Skin Texture: Collagen is strengthened by vitamin C, giving skin more suppleness and the ability to return to its original position after stretching. Skin that is high in collagen seems plumper and smoother, with fewer pores and an uneven texture.
-
Complementary Nutrients: It works in tandem with vitamin C to preserve the skin and increase collagen formation by stabilizing cell membranes. These are collagen's building components, and they are required for new collagen to form. Zinc promotes collagen synthesis and skin healing by stabilizing collagen and elastin fibres. Copper helps to cross-link collagen and elastin, which improves skin strength and suppleness.
-
Lifestyle Factors: UV light is the major cause of collagen degradation. Daily sunscreen treatment protects collagen fibres from breakdown. A diet rich in antioxidants, amino acids, and healthy fats improves skin health and collagen formation. Smoking increases oxidative stress and reduces collagen production, hastening skin aging. Water is necessary for collagen formation, thus, well-hydrated skin is stronger.
-
Topical Treatments: One of the most efficient ways to increase collagen in the skin is to apply vitamin C serums topically. Look for serums that include 10–20% L-ascorbic acid and other antioxidants like ferulic acid. These vitamin A compounds stimulate collagen production and improve skin texture by increasing cell turnover. Peptides cause the skin to produce more collagen, boosting firmness and elasticity.
-
Long-Term Benefits: Fine lines and wrinkles become less evident when collagen levels rise, resulting in a smoother complexion. Collagen helps keep skin firm, preventing drooping around the jawline, cheeks, and eyes. Increased collagen production leads to healthier, more resilient skin that appears youthful and beautiful.
Hyperpigmentation: Lightening Dark Spots and Uneven Skin Tone
Hyperpigmentation is a common skin condition characterized by dark spots and patches caused by an overproduction of melanin, the pigment responsible for skin color. Vitamin C is a highly effective substance for reducing hyperpigmentation and attaining a more even skin tone. Here's a complete information on how vitamin C and other therapies help with hyperpigmentation:
-
Understanding Hyperpigmentation: Sun exposure, hormonal fluctuations, inflammation, and aging are all potential causes of hyperpigmentation. Excess melanin is created in reaction to these triggers, resulting in uneven skin tone, black spots, and darker regions than your natural skin color. Tyrosinase is an enzyme that is essential for the synthesis of melanin, and vitamin C suppresses its action. Vitamin C lessens the production of melanin by inhibiting this enzyme, which lightens dark spots and stops new ones from developing. Vitamin C, being an antioxidant, guards against more UV damage to the skin, which exacerbates hyperpigmentation. It counteracts free radicals, which cause an excess of melanin to be produced.
-
Benefits: Improves overall skin radiance and brightness, giving a luminous, healthy appearance. It helps to lighten sunspots, pre-existing dark spots, and post-inflammatory hyperpigmentation, resulting in a more even complexion. By protecting the skin from environmental damage and lowering melanin production, vitamin C helps to prevent the formation of new dark spots.
-
Complementary Components: By preventing melanin from being transferred to skin cells, niacinamide improves skin brightness without causing discomfort and lessens existing pigmentation. Retinoids increase cell turnover by pushing pigmented cells to the surface, where they are lost, thus promoting skin regeneration. Exfoliate the skin to remove the top layer of dead, pigmented cells and improve absorption of brightening substances such as vitamin C. Kojic acid is a natural lightening agent that inhibits tyrosinase and works well in conjunction with vitamin C to provide a synergistic brightening effect. Liquorice Extract inhibits melanin production and soothes the skin, reducing the irritation caused by standard lightening treatments. Azelaic acid is an anti-inflammatory and tyrosinase inhibitor that lowers dark spots but is gentle on sensitive skin.
-
Best Practices: Over time, significant improvements in hyperpigmentation can be achieved with regular usage of vitamin C serums in the morning. Use sunscreen with at least SPF 30 every day to avoid new dark spots and boost sun protection as UV exposure can worsen hyperpigmentation. Vitamin C also helps. Use in combination with other medications, such as retinoids, AHAs, or niacinamide, for quicker and more pronounced effects. Use following cleansing and toning, and then follow with sunscreen and moisturizer. Start with lower dosages for sensitive skin and progressively improve tolerance.
Choosing the Right Vitamin C: Formulations and Stability
It is the most well-known. It is also the most potent and effective form of the vitamin. L-ascorbic acid, a bioactive form of vitamin C, can penetrate your skin's barrier. It is also the most stable configuration.
Stability Concerns: Ensuring Effective Vitamin C in Skincare
-
Degradation: When exposed to air, light, or heat, vitamin C, particularly L-ascorbic acid, oxidizes. As it oxidizes, it loses efficacy and transforms into dehydroascorbic acid, which provides little to no skin benefits and may even cause discomfort.
-
Color change: An oxidized vitamin C product frequently changes color, usually becoming yellow, orange, or brown. This discoloration suggests that the product has degraded and is less effective.
-
Loss of benefits: Vitamin C loses its antioxidant properties when it becomes unstable, which reduces its effectiveness in promoting the production of collagen, lightening the skin, and shielding it from the elements.
-
Exposure to air: When exposed to oxygen, vitamin C rapidly degrades. This is especially problematic for poorly packed commodities, such as frequently opened bottles or jars.
-
Exposure to light: UV radiation accelerates the deterioration of vitamin C, decreasing its effectiveness. Goods stored in transparent or clear packaging are especially susceptible.
-
Temperature: Vitamin C can decay more quickly at hot temperatures because it can become unstable there. Items that are stored in warm, muggy environments may not last as long.
-
pH Levels: For L-ascorbic acid to remain stable and effective, the formulation must have a low pH (below 3.5). However, such acidic environments can sometimes irritate, especially for sensitive skin types.
Selecting the Best Vitamin C Products for Your Skin
L-ascorbic acid is the most powerful and potentially useful form of vitamin C for oily or normal skin. Magnesium ascorbyl phosphate, a water-soluble vitamin C, reduces inflammation.
