COSRX Refresh AHA/BHA Vitamin C Booster Serum delivers potent exfoliation to refine skin texture and promote an even tone.

We appreciate its carefully balanced formulation featuring natural extracts from Kiwi and Dragon Fruit skins that target dead skin cells without compromising the skin barrier. The serum’s lightweight, watery texture absorbs rapidly, offering hydration without a heavy or greasy feel, making it particularly suitable for combination to oily skin types. This product supports a smoother and clearer complexion through consistent, gentle exfoliation.

Key Ingredients:

  • AHA (Alpha Hydroxy Acids): Enhances skin cell turnover to improve texture and surface smoothness.
  • BHA (Beta Hydroxy Acids): Penetrates the pores to assist in reducing congestion and clearing imperfections.
  • Vitamin C (from natural fruit extracts): Provides antioxidant support to brighten the complexion and promote an even skin tone.
  • Niacinamide 2%: Strengthens the skin barrier while helping to reduce redness and improve overall clarity.

How to Use:

  1. Apply a few drops of the booster serum onto cleansed skin, gently patting or pressing it into the face and neck before moisturising.

The Ritual Tip: For optimal results, introduce this serum gradually into your routine, using it initially every other day to allow your skin to acclimatise to the exfoliating acids without irritation.

Best pillow ever.
Size: King
How much did I like this pillow? My wife and I both loved it so much that we purchased another one. I think that says it all! The pillow arrives in a large box (king size pillow). It does NOT arrive all flattened and squished in a vacuum bag like some others do. I did place it on my back porch to air out for a while, just because that's what I do with any new bedding. I did not have any issue with scent or odors from either of my pillows. Its clearly well constructed with high quality materials. It comes with a smaller bag of extra stuffing if you want a slightly firmer pillow. We have not used any of the extra stuffing... we think the pillows are perfect as is! When I ordered the first pillow, I thought the price was a bit on the high side. After using it, I had no hesitation purchasing a second. This pillow is well worth the price. If anything, I feel this pillow is a great value at its price. Its not too hard, not too soft. Its the goldilocks pillow! I give this pillow my highest possible recommendation. Its simply a great pillow.

Excellent pillow, firm but more flexible than others of its type
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I previously bought a similar pair of pillows from Sleep Innovations, but they are now either out of stock or unavailable. This new brand is a bit softer and more comfortable than the original pair. It's good for sleeping on my side or my back. The pillow cradles and supports the head and neck in a more contoured way than some harder pillows. The price is reasonable. The only difference from Sleep Innovations is that this pillow does not have a zip cover. So there is no way to wash the exterior. I suppose that one could buy a zip cover for it at extra cost.

Side sleepers rejoice!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I have spent hundreds of dollars on pillows. I am primarily a side sleeper and every few years I find myself waking up with a "crick" in my neck accompanied by pain and tension. I have had this pillow for only two nights and I am leaving a positive review. It is firmer than one would expect based on first appearance and the "press" test. The surface stays cool and I can sleep any which way and I am still comfortable. Definitely recommend!

Too Soft for Him, Just Right for Me
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
My husband purchased this for himself but found it to be too soft for his preference. I decided to try it, and it worked well for me. While I agree it’s not as firm as either of us typically like, it still provided adequate support, and the shape retention held up nicely. Overall, it wasn’t a match for him, but it worked just fine for my needs.

Great for a side sleeper. Firm enough that it doesn’t collapse but soft and cool
