This is because vitamin C down-regulates an enzyme called tyrosinase that’s involved in melanin production.

This is for a few reasons.

Patel specifically recommends using a serum.

“The water-soluble vitamin C is more powerful than the fat-soluble variant.”

However, if you have sensitive skin, Patel says esterified vitamin C products may be less irritating.

Singh also suggests using vitamin C withtranexamic acidfor dark spots related to melasma.

If you apply vitamin C in the morning, Patel suggests using these other ingredients in the evening.

Safety Considerations

Vitamin C is safe for most skin types, but some people may experience irritation.

“The strongest form is the alcohol form, [which] can be irritating.

Switching to the fat-soluble milder form can be helpful.”

It’s best to stick to products with a vitamin C concentration between 10 and 20%.

Another important point to remember is that vitamin C is an unstable ingredient.

The Final Takeaway

Dermatologists regularly recommend vitamin C to treat dark spots on the skin.
