COSRX 15% Niacinamide Face Serum - 20ml
 
Revitalize your skin with the COSRX 15% Niacinamide Face Serum, a powerful yet gentle formula designed to transform your complexion. This 20ml serum is a game - changer in your skincare routine, packed with benefits that target multiple skin concerns.
 
High - Potency Niacinamide Formula
 
At the core of this serum is 15% niacinamide, a highly effective ingredient renowned in the skincare world. Niacinamide, also known as vitamin B3, works wonders for your skin. It helps to visibly reduce the appearance of enlarged pores, making your skin texture smoother and more refined. By regulating sebum production, it's an excellent choice for those with oily or combination skin, keeping shine at bay and preventing breakouts.
 
This serum also plays a key role in brightening the skin. Niacinamide inhibits the transfer of melanin to skin cells, gradually lightening dark spots, hyperpigmentation, and uneven skin tone. Over time, you'll notice a more radiant and even - toned complexion. Additionally, it strengthens the skin barrier, improving its ability to retain moisture and protect against environmental stressors like pollution and UV damage.
 
Lightweight and Fast - Absorbing
 
The COSRX 15% Niacinamide Face Serum has a lightweight, non - greasy texture that glides onto the skin effortlessly. It absorbs quickly, leaving no sticky or oily residue behind, making it suitable for use under makeup or as part of your nighttime skincare routine. The serum is formulated to penetrate deep into the skin layers, delivering the niacinamide and other beneficial ingredients where they're needed most for maximum effectiveness.
 
Gentle and Skin - Friendly
 
Despite its high - potency formula, this serum is gentle enough for daily use. COSRX is committed to using safe and effective ingredients, and this serum is free from harsh chemicals like parabens, sulfates, and phthalates. It's suitable for a wide range of skin types, including sensitive skin. However, as with any new skincare product, it's recommended to do a patch test before full - face application.
 
How to Use
 
After cleansing and toning your face, apply 2 - 3 drops of the serum onto your fingertips. Gently pat and smooth the serum over your face and neck, avoiding the eye area. Follow up with your favorite moisturizer to lock in the benefits. For best results, use the serum both in the morning and evening as part of your regular skincare routine.

Quality Case
Color: Pink
This is an All in Pne case. I really like the lavender color with sparkles. It is a little heavier than expected but I still love it!

Ok, but don’t use hand cream
Color: Black, Color: Black
I like the case for its ability to house the keyboard, the pencil and the iPad in one convenient place. I find that the magnetic closure and magnets holding the keyboard are not as strong as a previous case I had purchased. The keyboard is great, I like the touchpad and the backlight colors. The cover material is not hand lotion friendly! I’ve tried water and lens cleaning wipes, and neither gets this cover clean. I hesitate to use any chemicals because the material is the type that will get sticky and nasty, and I don’t like that. I’ve included a photo of what the cover looks like after using a lens cleaning wipe. If the magnets were stronger and the cover material easier to clean, I would buy again.

great case!
Color: Navy Blue
pros; the color is beautiful. I picked the navy blue. It is exactly as the description described. It goes very well with my blue iPad. The size is very precise and fits perfectly on my iPad. The magnet that holds the case together is very strong. The iPad itself can pivot vertically and horizontally using that magnet. This works very smooth. The magnet closure for the case itself is strong and holds well. The magnet that holds the keyboard in place also works very well. Cons; when the keyboard is in its correct position, it is difficult to angle the iPad in front into the provided grooves. The keyboard gets into the way. This prevents the iPad from reaching the grooves provided. The keyboard feels very light and cheap. The keyboard itself connected with the Bluetooth very easily. It works wonderful. I love the back light on the keyboard. The color of the keyboard is wonderful. However, as I said above, it does feel a bit cheap. But for 20 bucks, what can you ask for. When the case is folded together with the keyboard in the iPad, it is a bit bulky. But I knew that from the previous reviews and was expecting it. What I love most about this case is that the iPad can be removed using the magnet on the back from the keyboard portion, but it is still protected by the exterior plastic case. So in situations where I don’t need to use my keyboard, I can remove the iPad itself and know that it’s still protected overall I recommend this product.

Nice Case & Keyboard
Color: Blue
Love this case with a keyboard. I like using the keyboard vs using one on the screen of iPad. And the keyboard has rechargeable batteries instead of having to buy batteries. And it protects my iPad.
