Claimed Benefits:

  • Brightening: The star ingredient, Ascorbic Acid (Vitamin C), is known for its brightening properties. It may help improve the appearance of dark spots and hyperpigmentation, leading to a more even skin tone.
  • Antioxidant Benefits: Vitamin C is a powerful antioxidant that can help combat free radical damage, potentially reducing signs of aging like fine lines and wrinkles.
  • Skin Smoothing: The formula may help improve skin texture and reduce the appearance of blemishes and acne scars.
  • Boosts Collagen Production: Vitamin C plays a role in collagen production, which is important for maintaining skin elasticity and firmness.

Key Ingredient:

  • 23% Ascorbic Acid (Vitamin C): This is a high concentration of Vitamin C, which is the key active ingredient in this serum.

Who It May Be Suitable For:

  • This serum is ideal for those with dull skin, hyperpigmentation, or concerns about early signs of aging.
  • If you’re looking for a potent Vitamin C serum to address these issues, this could be a good option, but consider your skin type as well (see below).

Things to Consider:

  • High Concentration: A 23% concentration of Vitamin C is quite potent. While effective, it may be irritating for those with sensitive skin. It’s recommended to do a patch test before applying it all over your face.
  • Fragrance-Free: This is a plus for those with sensitive skin or those who prefer fragrance-free skincare.
  • Short Shelf Life: Vitamin C serums tend to degrade over time, especially when exposed to light and air. This serum’s smaller 20ml size and dark bottle may help preserve its potency for a longer period.

Overall, COSRX The Vitamin C 23 Serum appears to be a potent option for those looking to target concerns like brightening, blemishes, and early signs of aging. However, the high concentration of Vitamin C makes it more suitable for those with tolerant skin. Be sure to do a patch test and consider its shorter shelf life.
