How This Gentle Serum Helps Your Skin

This serum works in several ways to help your skin look and feel better. The 85% propolis extract helps calm redness while the 4% niacinamide helps fade dark spots that show up after spots heal. The special CentellAC-Rx mix (made from centella plant) helps your skin recover faster, while ceramides work to keep your skin barrier strong and healthy.

The formula is light and won't clog pores, making it great for skin that tends to be oily or gets spots often. Many people see calmer-looking spots within just 1-2 days, while dark marks start to fade with regular use over 4-6 weeks. The best part? It's made without harsh stuff like parabens and added scents.

Key Ingredients That Make It Work

This serum is packed with ingredients chosen to help your skin in multiple ways:

  • 85% Propolis Extract: This natural ingredient helps calm skin and keep moisture in
  • 4% Niacinamide: Helps fade dark spots and balance oil
  • CentellAC-Rx Complex: A special mix from the centella plant that helps skin heal
  • Ceramide NP: Strengthens your skin's natural barrier
  • Tea Tree Leaf Oil: Helps keep skin clear and fresh
  • Sodium Hyaluronate: Adds moisture without feeling heavy

These ingredients work together to help your skin look clearer and feel better. The formula suits many skin types because it balances helping spots while being gentle enough for everyday use.

How to Add This Serum to Your Routine

Using this serum is simple and fits easily into your daily skin care:

  • Morning and night: Apply after washing your face and using toner
  • Use 2-3 drops: A little goes a long way
  • Pat gently: Let it sink in before moving to the next step
  • Follow with: A light moisturizer and sunscreen (in the morning)

For extra care on stubborn spots, you can put a bit more on those areas. The serum works well with other COSRX products like their Salicylic Acid Cleanser before using the serum, or their Comfort Ceramide Cream after. The 40ml bottle typically lasts 8-10 weeks when used twice daily.

What Makes This Serum Different

COSRX has created a serum that stands out from others in several important ways. While many spot products just dry out skin, this serum helps calm and clear while also supporting your skin's health. The blend of propolis and centella is especially good for sensitive skin that gets upset by harsh products.

The formula is non-comedogenic (won't clog pores) and made without added fragrances that might bother your skin. It works for all skin tones to help with dark spots and can be used year-round. In summer, its light feel works well in humid weather, while in winter, it layers nicely under richer creams.

Who This Serum Works Best For

This serum is ideal for several skin types and concerns:

  • Oily and combination skin that needs balance
  • Sensitive skin that needs gentle care
  • People aged 16-45 who get occasional or regular spots
  • Anyone looking to fade dark spots left behind
  • Those wanting to strengthen their skin barrier

If you have extremely dry skin, you might want to pair this with a richer moisturizer. The good news is that 87% of users report that spots clear faster with this serum compared to using just spot treatments alone. It's made a real difference for people who want clear, calm skin without harsh effects.
