It's Skin Power 10 Formula VC & WH Effector REVIEW

May 24, 2015

Today I'll be reviewing It's Skin's Power 10 Formula VC and WH Effector.

Before I start on that though, I've recently reviewed the YE serum so to check that out, click here!


For my birthday last year, one of my bffs Caryn was generous enough to let me go on an online shopping spree! She gave me a budget and asked me to spend it on anything I wanted on, and i gladly accepted ^^ This was how I was first introduced to and I've been buying from them ever since.

I went through their selection of products and after some Google searching, I decided to get 2 products from It's Skin's Power 10 Formula series: The Vitamin C effector and the Whitening (WH) effector. I also wanted to get Etude House's AC Clinic Toner but it was suddenly out of stock...

Anyhoo, without further ado, let's get to the review!

*OCTOBER 2015 UPDATE: I noticed that I got a lot of views for this review but since its one of my first few, its not very detailed, so I decided to edit it a bit and update it with more of my experiences with these two products ^^*

*disclaimer: This is my honest review and have not been paid to make this post*


It's Skin is a Korean skincare company and I chose these two products because I wanted a product that could help lighten my scars and my skin in general. I could have gone with a cream but i decided to go ahead and try formula/serum instead *I've never tried using serums/essences before this*. Since I was on a budget, I wanted to make full use of it and buy a product that actually worked. All the high-end products were quite pricey and those that came under my budget came in SUCH little portions/bottles. I then came across It's Skin's Power 10 Formula Series. The price was reasonable so I decided to search the product up on Google. To my surprise, there were quite a few good reviews on the product!

I'm assuming that the line is called Power 10 since it started with 10 products for the line, but i think that they've recently added more.

Here's a photo of all the effectors and their properties:

Since what I wanted to accomplish was skin brightening/scar fading I decided to go with the VC Effector (which was rated number 1 among all of them) and the WH Effector


So far here in Malaysia I've only seen It's Skin's serums being sold on The Power 10 series is great because they have a wide range of serums that cost from RM39.90 to RM45.90 (Only the SYN-AKE and Propolis cost RM45.90). These serums cost a fraction of what most serums go for, which is usually RM90-200 or even higher.


The serums do not come with their own box so there isn't any information about the product except for the Korean at the back of the bottle. The serums are package like any other serum in the market; in a glass bottle with a dropper. The bottle comes sealed and has a plastic cap for the dropper. I don't know why but I kind of feel like serums with covers look better than those without. It give a complete look to it (am I making sense)

I didn't have any problem with getting every last drop of my serums as well. I'm not sure if the serums are available in sizes above 30ml, but I alternated the two serums and the two 30ml bottle lasted me a good 7-8 months, so I guess one bottle alone might last for about 4 months.


The VC Effector contains vitamin C derivatives with whitening and brightening properties, as well as green tea components. Vitamin C has the following effects:

- anti-aging properties to prevent signs of aging
- promotes collagen formation
- fade scars and dark spots
- brighten complexion

The reason why I'm so keen on vitamin C is because about a year ago, I tried using lemon juice to fade scars and to my surprise, it did work. I wanted to try a more refined and medically tested approach with vitamin C, hence my decision to get this serum.

The WH Effector contains arbutin and whitening agents, and arbutin is in a lot of whitening products as well. I've used a few products with arbutin because after a little bit of research on arbutin I found that:

- arbutin counter effects of UV rays
- it is the most common skin lightening agent


The VC Effector has a thick consistency and smells very citrus-y. I find that its quite thick and feels slightly heavy on the skin. My oily skin has no problem with it, but I do recommend using this only at night since it's thick, gives shine and its vitamin C (which should not be exposed to direct sunlight)

The WH Effector has a very thin consistency, the total opposite of the VC Effector. The smell is very faint but it smells..."clean". The smell is barely discernible. If you're feeling fancy, this serum can be used in the morning as well, but a slight sheen will be visible.


I usually only use serums at night and encorporate it as follows:

Cleanser - Toner - Essence - Lotion - Acne - Serum - Moisturizer

For serums, it is important to know how to layer your products. Start with the thinnest consistency while working to the thicker ones. You can use multiple serums every night according to your preference, but do allow the serum to absorb into your skin for 2-3 minutes before layering another layer of serum on top.


For the VC Effector:

*Edit: I have taken more photos of this serum because I repurchased it and I just love it so much!*

This serum was quite thick and I used it my night time routine. It smell very citrus-y and just smells jam packed with Vitamin C. 

After about 2 months of using this I saw that some of my scars lightened. I remember one day my sister complimented my skin saying that whatever I was doing was working because my scars looked like they faded. So I guess that means that this product works! I really like the smell and for the price and its effects, its not that bad either. This serums absorbs fairly well but it is a little bit sticky, but not sticky enough that it feels tacky. I wouldn't wear this out in the morning/out in the sun as it not only is sticky, but contains concentrated vitamin C as well. I usually apply it at night.


For the WH Effector:

Compared to the VC effector this serum was lighter and more runny. It doesn't really smell as strong as the VC but it has a rather pleasant clinical smell.

I switched to using this after using the VC effector for one month. Because of the results I had quite high expectations for this but I was let down :O I didn't see any visible results. It absorbs quite fast and isn't sticky but as for any visible results...I didn't see anything.



I really like the VC effector and because of the results I'm actually looking into buying other brands' Vitamin C serums. I watched on WishTrendTV that the Pure Vitamin C20/C21.5 Advanced Serum was really good so I'm kinda keeping my eyes open for it or any other Vitamin C serum that I might come across.


UPDATE: I HAVE bought the C20 serum! Click here to read my review on that.

As for the WH effector...meh. I still do apply it but I'm only trying to finish the bottle. It might be doing something to my skin from the inside but as far as visible effects, I don't see any.


I won't be repurchasing the WH Effector but I'll definitely be repurchasing the VC Effector on! And since they have the whole Power 10 Formula line I might be trying out the other serums as well (I've been doing a bit more research on collagen and propolis).

(PS. I'm already on my third bottle of the VC Effector as of October 2015)

As you can see my VC effector is aaaaaaalmost done *not really* and I plan on repurchasing it when it does finish ^^

Thanks for reading my honest review of It's Skin's Power 10 Formula VC and WH Effectors! I hope you enjoyed it! ^^ If you would like to read more of my reviews, please click here!

Thanks for reading!



  1. Thanks for your review. You might've been seeing a surge in visits to this post because the VC Effector was in this month's 3b beauty box subscription ( I'm also trying to find out more information about it before applying it.

    1. Woah, no wonder! Thanks for telling me ^^ I hope you found my review helpful! :D

  2. Thanks for your review. You might've been seeing a surge in visits to this post because the VC Effector was in this month's 3b beauty box subscription ( I'm also trying to find out more information about it before applying it.

  3. I've heard a lot that the WH one does nothing
    just a few users rave about it
    It make me unsure about picking the WH

    1. I bought it because it has Arbutin and other whitening properties, but to be honest I saw little to no effects on my skin. I like that its light and can be applied during the day, but other than that, I wouldn't repurchase this product. It depends on you I guess. Since the price is affordable, it would be good to try it out for yourself. Everyone's skin is different and it may work better for you :)

  5. I´ve heard a lot about it (all good things), so I thought "I need to buy it!!!".I bought the VC Effector on last week and I´ll begin to use today.I´m so excited for this.
    I bought the VC effector and YE effector (the most popular here in Japan).

    1. The VC Effector is a really good product. It works well and its not too expensive as well. Glad you found my review helpful! :)

  6. Thank you so much for the review! I have one question, do you also wait 2-3 minutes for the VC effector before the next step?

    1. Hi Ray, thanks for commenting! Yes, I usually wait around 2 minutes for any serum I apply to fully absorb :) Hope I helped!

  7. Hi, how many drops of the serum do u usually put?

    1. Hi Xinyuan, I usually use 2-3 drops and its enough for my whole face :)

  8. Hi! This really helped, but I was wondering if you've tried the po effector. Its for reducing pores apparently and I got that one by mistake. If you haven't tried it, do you have any thoughts, judging by the description?
