COSRX The Vitamin C 13 Serum delivers a clinically effective solution to visibly fade blemishes, dark spots, and freckles, promoting a more even skin tone with regular use.

This serum penetrates deeply to refine overall skin texture, smoothing rough patches and supporting the reduction of enlarged pores. The lightweight, non-greasy formula absorbs quickly into the skin, leaving a balanced, refreshed finish without irritation or heaviness.

Key Ingredients:

  • Vitamin C (13% concentration): Brightens complexion and helps fade hyperpigmentation
  • Super Vitamin E: Strengthens the skin barrier and protects against environmental stressors
  • Hyaluronic Acid: Provides long-lasting hydration and enhances skin elasticity
  • Niacinamide (if present, but not in provided info, so exclude)

How to Use:

  1. Apply 2-3 drops onto clean, dry skin after cleansing and toning.
  2. Gently pat the serum into the face and neck until fully absorbed.
  3. Follow with moisturiser and sunscreen during the day.

The Ritual Tip: For optimal skin tone improvement, pair this serum with a broad-spectrum SPF during daylight hours to prevent further pigmentation and support skin health.

Best of all, they are more than worth the money! Highly recommended!!
Size: King (20" X 36"), Color: 14 - Blush Pink, Number of Items: 2
This is a great brand! The products are quality, and well made! These pillowcases are extremely soft and comfortable! The fabric is luxurious! The colors that I ordered are true to description! And these pillowcases are generous with size - it isn’t difficult to put your pillow in th case!! The cases are not slick/slippery! They are soft and comfortable (I know I already said that, but it’s worth repeating!! They look great on the bead like a sham as well!! Best of all, they are more than worth the money! Highly recommended!!
