Vitamin C fades dark spots, evens out skin tone, and protects against the sun and pollution that leave skin dull. It is one of the few actives with decades of research behind it, and one of the most reliable ways to get visible brightness.Every Vitamin C serum at PrimeSkin.pk is 100% original, imported, and stored properly so the formula is still active when it reaches you. Vitamin C oxidises when it is handled badly, and a mishandled bottle is a wasted bottle.Not sure which one suits your skin? Our guide to the 5 best Vitamin C serums in Pakistan compares each pick by skin type and strength.

How to Choose the Right Strength

Strength is the decision that matters most, and starting too high is the main reason people give up on Vitamin C.
  • 10%: The starting point. Gentle enough for dry, sensitive, or first-time skin, and still effective on dark spots with consistent use.
  • 15%: The middle ground. Faster brightening, often paired with peptides or gentle exfoliants.
  • 23% and above: For skin that already tolerates Vitamin C well. Stronger and faster, but more likely to tingle or irritate if you rush into it.
Whatever strength you pick, give it eight weeks before you judge it. Vitamin C is not an overnight ingredient.

How to Use Vitamin C Serum

  • Start with a gentle cleanser on clean, dry skin.
  • Apply two to three drops to the face and neck, and pat it in rather than rubbing.
  • Follow with a lightweight moisturizer.
  • Finish with a broad-spectrum sunscreen. Vitamin C without SPF undoes most of what the serum is doing.
  • Sensitive skin should start every other morning and build up from there.
Pro tip: Vitamin C in the morning, retinol at night. That pairing covers brightening and anti-aging without the two ingredients fighting each other.

Buying Vitamin C in Pakistan

Vitamin C is the easiest active to get wrong, and not because of the formula. It degrades with heat, light and time. A serum that has been sitting in a hot warehouse or on a shelf for two years has already oxidised, and an oxidised serum does nothing regardless of what the label says.That is what you are actually paying for when you buy authentic imported stock. Fresh product, stored correctly, sealed properly. If a serum has turned dark orange or brown in the bottle, it is finished, and no price makes that worth buying.

Vitamin C Serum FAQs

Can I use Vitamin C serum every day?

Yes. Once daily in the morning is the standard, and it works best that way because the antioxidant protection is most useful during the day. Always follow with sunscreen.

Is Vitamin C suitable for sensitive skin?

Yes, but start low. A 10% formula, applied every other morning for the first two weeks, is the safe route. Patch test first. Skip the 23% formulas until your skin is used to the ingredient.

Can I use Vitamin C with niacinamide?

Yes. The old claim that they cancel each other out has not held up. In practice most people split them anyway, Vitamin C in the morning and niacinamide at night, because that suits what each one does best.

Why has my serum turned orange or brown?

It has oxidised. Vitamin C reacts with air, light and heat, and once it changes colour it has lost most of its potency. Keep the bottle sealed, out of direct sunlight, and use it within a few months of opening.

How soon will I see results?

Four to eight weeks for visible brightness and smoother texture. Stubborn pigmentation takes longer, closer to twelve weeks, and only if you are wearing sunscreen daily.
