Vitamin C: A Skin Brightening Ingredient

Vitamin C is an essential nutrient commonly known as the ascorbic acid. It is a water-soluble vitamin a human body cannot synthesize or store. It flushes it out through urine, but a small amount is kept as a reserve. But as vitamin C is responsible for running vital bodily functions, so it must be ingested daily. You can ensure this by eating more fruits and vegetables.

Key characteristics of Vitamin C:

Vitamin C carries the following features:


Antioxidant: Vitamin C controls cell damage meted out by the free radicals in the body.

Collagen biosynthesis: Humans use collagen to make connective tissue, including skin, bones, cartilage, and blood vessels. It is needed in wound healing as well. Vitamin C helps in making collagen strands in the skin.

Iron absorption: Vitamin C plays a crucial role in iron absorption by the body.

Main Benefits of Using Vitamin C

Vitamin C has several advantages to its name, including but not limited to:

  • Reduces pigmentation: Vitamin C checks melanin production, a pigment that causes skin discoloration. Its regular use reduces hyperpigmentation, including dark spots, age spots, and melasma.
  • Even skin tone: Whether uneven skin tone is a result of sun exposure, hormonal changes, or some other factor, Vitamin C can address it efficiently. When pigmentation reduces, the skin looks more even.
  • Skin brightening: Vitamin C can overturn the dullness caused by environmental factors such as pollution and UV radiation. It does this by promoting healthy skin cell turnover for fresher and brighter skin.
  • Fading scars: Vitamin C helps produce collagen and repairs tissue, both of which help fade scars, including acne scars and post-inflammatory hyperpigmentation.

What to Consider When Buying a Vitamin C Serum?

As you head to purchase a Vitamin C serum, read the ingredients list to spot the following in it.

Active ingredient

Different Vitamin C serums have different active ingredients, such as:

  • L-ascorbic acid (LAA): LAA hydrates and makes the skin firm. It is known for controlling hyperpigmentation and suits almost all skin types. However, LAA is unstable and degrades when left in contact with light or heat.
  • Sodium ascorbyl phosphate (SAP): SAP is more stable than other active ingredients. Being less acidic, it suits sensitive skin perfectly. SAP is also found to be helpful against acne.
  • Magnesium ascorbyl phosphate (MAP): From dry skin to sensitive, MAP works well against all skin issues, especially hyperpigmentation.


Though ideally, your vitamin C serum should have 10-20% of the active ingredient, a slightly higher than 8% concentration is effective for all skin types. But beware, a higher percentage can irritate your skin.


Exposure to light and oxygen can make Vitamin C serum ineffective. To maintain its potency, it must be kept in a dark glass bottle. This helps the active ingredient retains its effectiveness for a long time.


Find a reputed company that produces high-quality skin care products. One way to ascertain this is through the reviews: read online or ask your friends or family for recommendations.

Dispensing design

A design that preserves the effectiveness of the vitamin is the best design. However, it should also be capable of releasing a precise amount only to prevent any wastage. Most importantly, it should be easy to use.

Chemical vs. natural

Both chemical and natural vitamin C serums are effective. However, they differ in many ways. Let’s understand:

Chemical-based Vitamin C serum: To prepare a synthetic vitamin C serum, the active ingredient is first derived from a natural source and then modified chemically. This is then used to prepare the product. However, it is unstable and requires other stabilizing agents whose concentration is one of the reasons for irritation on sensitive skin. The plus point is that it is cost-effective.

Natural vitamin C serums: Vitamin C is present in many plants. The composition to make serum is taken from the plant and does not require any additional preservatives due to the presence of several other nutrients. These substances, such as enzymes, bioflavonoids, and phytonutrients, provide additional benefits. Together, they improve the efficiency and penetration of the vitamin C serum.

Now that you know the difference between the two, you may pick as per your requirements and preferences.

How to Apply Vitamin C Serum on Face at Night?

The answer to how to use Vitamin C serum on face at night is simple. Just follow the procedure as under:

  • Clean your face thoroughly
  • Release a drop of vitamin C serum and slather it gently using your clean fingers
  • Finish your nightcare regime with a moisturizer

Why apply Vitamin C at night time?

As discussed earlier, Vitamin C serum loses its effectiveness in light. Using it during the daytime increases the chances of photosensitivity. Therefore, use Vitamin C serum at night when the body is repairing and replenishing the tissues while you are sleeping. This is just the right time to allow vitamin C to act. And when the skin is cleansed well, the absorption is even better.

What other products work well with vitamin C?


Combined with other skin care products, Vitamin C can make your skin healthy and bright in less time.

  • Hyaluronic acid: Hyaluronic acid has the ability to lock hydration in your skin. When applied with Vit C, it calms irritated sensitive skin.
  • Niacinamide: Niacinamide is also a brightening agent, like Vitamin C. While the latter suppresses the tyrosinase enzyme that makes melanin, niacinamide effectively moves melanosomes from the melanin. When you apply both, melanin synthesis reduces even faster.
  • Vitamin E: Both vitamin E and vitamin C are antioxidants that work to avert sun damage.
  • Retinol: While retinol is a type of Vitamin A effective against fine lines, wrinkles, and dryness, Vitamin C is an antioxidant that fades dark spots. When used together, they improve the overall appearance of the skin. But use both at different times: retinol at night and Vitamin C during the day.


  • Rinse your face thoroughly. Pat it dry
  • Run Vitamin C serum patch test 24 hours before using it
