I got the Oriflame Oxygen Boost capsules last year when they were offered at a discount. before using these capsules, I had tried and loved The Body Shop Vitamin C capsules. I used these last month and I must say I am impressed with the texture and feel of the skin after using these capsules.
How To Use:

1. Break the capsule on the end by twisting the smaller part.
2. Squeeze out serum from the capsule and distribute it evenly all over the face and neck.
3. Massage gently and top it p with a night cream.

I do not know how well these would work for me in summer since my skin breaks out easily when I apply intensive hydrating products but I always need these sort of things for winter.
Since it was cold here in Seoul last month and my skin was dry, I tested these out for a fortnight. They worked well for me and my skin felt so soft, I did not develop any dry patches like I usually do in winter for a month. The serum absorbs well in the skin and it hydrates the skin from inside out!
Another good thing is that these are paraben and color-free too!

The effect from using these face capsules lasted for a couple of weeks after finishing using the 14 capsules. I do not know about the Oxygen Boost effect and how to measure it but I was quite impressed with how smooth and soft my skin felt after applying these especially even after the initial 14 days. I did like it as much as The Body Shop Vitamin C capsules and I would repurchase this whenever my skin needs an extra pick me up!
