Can vitamin C remove pigmentation?
It can lighten dark spots and even tone by inhibiting melanin production. Best for sun spots and PIH; melasma may need additional treatments.
How long until I see results?
With daily use (and SPF), many see visible improvements in 8–12 weeks. Stubborn pigment can take longer.
What concentration is best?
For L-ascorbic acid, 10–20% is a common sweet spot. Sensitive skin may prefer lower % or derivatives (e.g., MAP, SAP).
Which ingredients boost results?
Vitamin E + ferulic acid can stabilise and enhance vitamin C; niacinamide and hyaluronic acid support brightening and tolerance.
Does vitamin C increase sun sensitivity?
Vitamin C itself isn’t photosensitising, but daily SPF is essential to prevent new spots and protect brightening progress.

Vitamin C serum is a popular choice for treating pigmentation, but its effectiveness can vary depending on the specific type of pigmentation and individual skin conditions.

What Vitamin C Can Do for Pigmentation

Vitamin C is known for its skin-brightening properties and ability to reduce the appearance of dark spots, sun damage, and other forms of hyperpigmentation. It works by inhibiting the enzyme tyrosinase, which is essential for melanin production.

  • Choose Your Vitamin C Type
  • For maximum potency, pick L-ascorbic acid (10–20%); for sensitive skin, try derivatives like MAP/SAP/AA2G.

  • Patch Test First
  • Apply a small amount behind the ear or on the jawline for 24–48 hours to check for sting or redness.

  • Apply on Clean, Dry Skin (AM)
  • After cleansing, apply 3–4 drops to face/neck. Let it absorb 60–90s before the next layer.

  • Layer Smart
  • Follow with niacinamide or hydrating serum, then a moisturiser. Avoid layering immediately with strong acids if you’re new.

  • Lock with Daily SPF
  • Finish with broad-spectrum SPF 30+ every morning. Reapply when outdoors to protect results.

  • Be Consistent
  • Use daily for 8–12 weeks. If irritation occurs, reduce frequency to every other morning and rebuild.
