Easy to use. Perfect for items you might end up returning.
Reload type: One Time Reload
First thing to note is that this is easy to use. Select whatever amount you want, how often you want it (one time, a specific date, etc), and then click buy and confirm the payment method. I normally only have to wait a few minutes for the process to go through and get the funds added to my balance.
I like using this option for the very rare times I order something that I'm not sure I'll end up keeping, such as buying shoes or other clothing. Items that say they're the same size might not fit correctly for some reason and I'll have to return it. I find the return process is faster and easier than using a card where I'll have to wait until the money is put back on the card.

Best skin care product ever tried
I am 74 years old and have been using this product for 23 days. I could see a difference the first time using it. My face was a lot smoother and hydrated. I apply it after cleansing my face morning and night followed by my regular moisturizer. It has diminished wrinkles and makes my face glow. It also blends well with liquid foundation. I have been getting compliments but have not told anyone what I am using yet. It also helps to smooth the tops of my hands and arms. I have tried many skin care products and never gotten results like this.

Amazing Serum
This serum is one of the best I’ve ever used, & I’ve tried many. It’s non-greasy, light, absorbs into skin well,, & has really improved the texture of my skin. I am amazed at how well it works on fine lines, deep wrinkles ,& large pores. Wish I had taken a before & after photo. Highly recommended, & I have mature skin.

Noticeable after one use!
Okay, I am writing this after receiving this product as of yesterday. After washing face last night I applied a liberal amount all over my face. I have a few large melasma spots on my face and pay close attention to them. I also have a large spot on my chest, so to my surprise this morning I immediately noticed they were all significantly lighter in darkness!!!! I cannot tell you how much my skin has responded to this product. I could only "hope' it would do something to improve the appearance,, but over night? YES! But, to anyone who reads this I have not had luck with other products I have tried and used for weeks. So, I imagine this is a case by case situation. What I can say is this product feels amazing on my skin. The texture is silky and does blend well with other skin products. I look forward to continuing to use it and applying it to my hands as well since I also have dark spots accumulating there. Overall I am blown away with the quality of this product. It was also packaged well and the bottle is very nice. You can tell alot of thought was put into this brand and the ingredients. thank you! Thank you! I strong ly recomment this to anyone who has melasma, sun spots, fine lines or dry skin. I am now a believer in korean skin care for anti aging.

A Korean Skincare Wonder!
This is truly an amazing skin product. I give it four stars only because it's a work in progress. I anticipate more great news to come. Regular use (two pumps a day, one a.m., one p.m.) are now beginning to reflect success. Skin on face is plumper. Big news is that the skin on the back of my hands - which I've ignored for years - is taking on a new dimension. All of this at such an affordable price. Can't wait to see the total impact. Love it
