Glutathione vs. Vitamin C: Benefits Compared

Skin brightening and lightening:

  • Glutathione: Works by prohibiting melanin production, which has the potential to lead to lighter, more even-toned skin.
  • Vitamin C: Fades pigmentation, brightens dullness, and gives skin a fresh glow without altering your natural tone.

Both are equally effective, but Vitamin C is more widely available.

Anti-Ageing Benefits

  • Glutathione: Supports cell renewal and slows down visible signs of aging when taken consistently.
  • Vitamin C: Stimulates collagen production, helping reduce fine lines and improve skin firmness.

Availability

  • Glutathione: Mostly available as oral supplements, a few products or injections
  • Vitamin C: Widely available in foods, tablets, creams, and topical serums

Vitamin C is a clear winner in this aspect.

Overall Verdict

For beginners, Vitamin C is the place to start, due to its proven efficacy and safety for those new to skincare. It is also widely available in different forms, which improves accessibility.

Glutathione may be the choice for those struggling with pigmentation or looking for internal detox and wellness benefits.
