What makes Pure Vitamin C so special?

Properties: Antioxidant, Anti-agIng, Brightening, Fights dark spots
Vitamin C is a powerful antioxidant used in cosmetics and dermatology to smooth, brighten and even the skin tone. L-ascorbic acid is the purest active form of Vitamin C. With a fast absorption profile that penetrates the skin to deliver its full benefits, L-Ascorbic Acid is the only biologically active form of Vitamin C with clinically proven effectiveness. For this reason, it’s the form most used and recommended by dermatologists.
Vitamin C derivatives, such as Sodium Ascorbyl Phosphate, Glyceryl Ascorbate and Tetrahexyldecyl Ascorbate, have a far more limited action.

Making sure your skin gets enough Pure Vitamin C

The body can’t produce its own Pure Vitamin C (L-Ascorbic Acid). Instead, we obtain it through supplements or diet – in foods like oranges, broccoli, leafy greens, grapefruit, and peppers. However, most of the Vitamin C we ingest never reaches the skin. Insufficient supplies mean that the skin can’t defend itself against external stressors such as UV rays, tobacco and pollution. As a result, dullness, hyperpigmentation and dark spots (caused by sun exposure, age and acne marks), open pores, lines and wrinkles may appear. This is called early or premature aging. Dermatologists therefore recommend applying Pure Vitamin C topically every day.

Why is Pure Vitamin C so beneficial for the skin?

As a powerful antioxidant, Pure Vitamin C (L-Ascorbic Acid) neutralises free radicals responsible for premature skin aging and hyperpigmentation (caused by sun exposure, age & acne marks). It inhibits the synthesis of excess melanin pigments by melanocytes cells in the epidermis. This helps even your skin tone and prevent or reduce dark spots. Pure Vitamin C (L-Ascorbic Acid) also stimulates the production of collagen and elastin in the dermis for firmer, smoother, younger-looking skin with less visible pores.

How stable is Pure Vitamin C?

Pure Vitamin C is known to be an unstable molecule. It reacts to light, oxygen and pH changes, making it notoriously difficult to formulate.
L’Oréal Paris laboratories have achieved the prowess of stabilising Pure Vitamin C to make Revitalift Clinical Pure Vitamin C Serum potent from the first to last drop.
  • 1
    The formulation has a balanced pH similar to the skin’s own pH, to keep the Pure Vitamin C stable and favour good tolerance.
  • 2
    Optimised industrial processes provide a temperature-controlled environment to preserve the integrity of the Pure Vitamin C.
  • 3
    Protective packaging – including inert glass, opaque materials, anti-UV lacquering and a rubber airtight pipette – keeps out oxygen and sunlight.

What other active ingredients work in synergy with the Pure Vitamin C in the serum?

• Antioxidant Vitamin E helps boost and recycle Pure Vitamin C’s antioxidant power.
• Refining Salicylic Acid enhances Vitamin C ‘s anti-inflammatory and antibacterial properties, which are beneficial for combination skin. It resurfaces, clears pores and refines the skin texture.
• The brightening, smoothing action of the Vitamin C is also enhanced by anti-aging and hydration boosters: Adenosine + Dipeptide (anti-wrinkle), 2 types of Hyaluronic Acid (plump and hydrate) and Glycerin (moisturise).

FAQ

Evething you need to know about Melasyl

1. What causes uneven skin tone and pigmentation?
Uneven skin tone and pigmentation are usually caused by melanin imbalance, which can be triggered by sun exposure, post‑acne marks, ageing and environmental stressors like pollution. In darker or melanin‑rich skin, pigmentation issues can also occur after inflammation or breakouts. Incorporating a potent antioxidant like Vitamin C helps target excess melanin production and supports a more balanced complexion by neutralising oxidative stress and encouraging cellular renewal.
2. How does Vitamin C help with dark spots and pigmentation?
The active form of Vitamin C, L‑Ascorbic Acid, is scientifically proven to inhibit melanin synthesis by reducing tyrosinase activity, the enzyme responsible for melanin creation. This helps fade dark marks, improve visible discolouration and support a more even skin tone over time. At the same time, its antioxidant properties protect skin from environmental damage that can worsen pigmentation.
3. Can Vitamin C make my skin look brighter and more radiant?
Yes. Because Vitamin C neutralises free radicals, it helps skin appear brighter and more luminous by reducing dullness and supporting a more uniform tone. This not only addresses pigmentation but also enhances natural radiance, giving skin a healthier-looking glow with regular use.
4. How long does it take to see results with Vitamin C?
Most individuals begin noticing enhanced brightness and gradual fading of dark spots within 4–8 weeks with consistent use, although deeper pigmentation may take longer to improve. Regular application paired with daily SPF maximises protection and results.
5. When should I apply a Vitamin C serum in my routine?
A Vitamin C serum should ideally be applied after cleansing and before moisturiser. Many experts recommend morning application to protect skin from daily environmental stressors, but it can also be used in the evening if your routine suits that better.
6. Is Vitamin C safe for all skin types, including sensitive skin?
Most L’Oréal Paris Vitamin C formulas are formulated to be well‑tolerated by a wide range of skin types. If you have sensitive skin, start with a lower concentration or use every second day initially. Patch testing is recommended for those with reactive skin to ensure comfort and avoid irritation.
7. Can I use Vitamin C with other skincare actives like niacinamide or sunscreen?
Yes. Vitamin C works well alongside niacinamide, which enhances barrier support and further improves tone and texture. It is essential to pair Vitamin C with a broad‑spectrum sunscreen daily, as sun exposure can counteract its benefits and worsen pigmentation.
8. Will Vitamin C remove acne scars and post‑inflammatory marks?
Vitamin C does not erase scars instantly, but by aiding melanin regulation and supporting collagen synthesis, it can help diminish the appearance of post‑acne marks and smooth tone over time when used consistently as part of a complete skincare regimen.
9. Can Vitamin C prevent uneven tone from happening?
Yes. Regular use of Vitamin C helps defend against oxidative damage from UV rays and pollutants, both of which contribute to uneven tone. By protecting skin at the cellular level, it supports preventative care that keeps complexion more even and resilient.
10. Why is Vitamin C by L’Oréal Paris a trusted choice for pigmentation concerns?
L’Oréal Paris formulates Vitamin C products with scientifically validated concentrations of pure Vitamin C and complementary actives to maximise penetration and antioxidant defence. These serums are tested for efficacy on uneven tone, dark spots and radiance, ensuring noticeable improvements when used as directed in your daily routine.
