What Makes This Serum Special
The COSRX Refresh Booster Serum stands out with its gentle yet effective three-in-one approach. It combines AHA (glycolic acid) to help sweep away surface cells, BHA (betaine salicylate) to help clear pores, and vitamin C to brighten your skin tone. The best part? These work together without being too strong for most skin types.
The magic comes from the Golden-Rx Complex - a blend of kiwi and dragon fruit extracts that makes up 57% of the formula. These fruits are packed with good-for-skin helpers that support your skin's natural glow. The light, fast-sinking texture feels fresh, not sticky, making it easy to add to your daily routine.
How It Helps Your Skin
This serum works in many ways to help your skin look and feel its best. First, it helps clear away the build-up that can make skin look dull. The AHA works on the surface while BHA goes deeper to help keep pores clear. Over time, this can lead to smoother skin with fewer bumps.
The vitamin C and alpha-arbutin in the mix help fade dark spots and even out skin tone. They work on marks left behind from past breakouts or sun damage. Meanwhile, sodium hyaluronate and glycerin keep your skin feeling soft and plump with moisture. With daily use, you'll notice a more even, bright, and fresh-looking face.
- Helps smooth rough texture
- Supports a bright, even tone
- Keeps skin hydrated
- Helps clear and refine pores
Who Will Love This Serum
This gentle but mighty serum works well for many skin types. If you have oily or combination skin, you'll love how light it feels while still helping to keep pores clear. Those with sensitive skin will find the soothing ingredients like panthenol and allantoin help calm any redness.
People in their 20s to 40s who want to keep their skin looking fresh and clear will find this serum hits all the right notes. It's also great if you live somewhere warm or humid since the texture is so light. While it works for all skin tones, it's especially good at helping with dark spots and uneven tone for deeper skin colors.
- Great for oily, combination, and sensitive skin
- Works well in warm or humid weather
- Helpful for all skin tones
- Perfect for both preventing and fixing skin concerns
Simple Steps to Glowing Skin
Using this COSRX serum is easy to fit into your routine. After washing your face and using toner (if you have one), place 2-3 drops onto clean fingertips. Gently press and pat the serum across your face and neck. The light texture sinks in fast, so you only need to wait about five minutes before moving on to your next product.
For best results, use this serum in your evening routine. If you want to use it in the morning too, just be sure to finish with SPF 50+ sunscreen, as exfoliating ingredients can make skin more sun-sensitive. Most people see a subtle glow right away, but the real magic happens after 4-8 weeks of steady use when skin tone looks more even and pores appear smaller.
What's Inside (And What's Not)
The COSRX Refresh Serum brings together simple but mighty helpers for your skin. Beyond the main active ingredients, you'll find niacinamide to help calm and balance, panthenol to soothe, and allantoin to support skin repair. These work together to make the formula gentle enough for regular use.
Good news for many - this serum is cruelty-free, paraben-free, and reef-safe. While it does contain a touch of bergamot oil for a light scent, the formula doesn't rely on heavy perfumes. The bottle is made to keep light out, which helps the vitamin C stay fresh and strong. Each 30ml bottle lasts about 2-3 months with daily use, giving you plenty of time to see how your skin responds.
- Free from parabens
- Cruelty-free formula
- Contains light natural scent
- Lasts 2-3 months with daily use
