This new product contains an additional of 2% Vitamin C in their product making it a whole 12.5% vitamin C with Hyaluronic Acid which makes it a very powerful serum for your skin. 

In this post I'll share with you guys some of my personal thoughts and review after trying out this new Kiehl's - Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C product. Focusing on their tagline which is  #cthedifference Kiehl's is committed to bring significant and visible change to your skin after continuous use of their Vitamin C. Since Kielhs is a dermatologist and clinically tested skincare brand they have done their research and this new 12.5% Vit C is better and faster in delivering visible results after being clinically tested. 

This new Kiehls12.5 percent vitamin C is said to be a powerfuanti-wrinkle treatment too fight dullness, fine lines and wrinkles and dryness. It is also formulated without Parabens making it super safe for your skin. The product claim to be a powerful antioxidant booster to improve skin texture, reduce visible lines and wrinkles and make your skin look more radiant and bright.

Massage into the skin
Quickly absorbs into the skin . It might give you a warmth sensation once the product absorbs into the skin but its normal .

Direction of Use 

The product comes in a brownish glass container and a tube to press to product out. The brownish bottle container is designed in that way to protect the product from oxidation since Vitamin C is very prone to oxidize that's why we should always make sure to store them in room temperature and away from the Sun. The packaging itself is very effective for use, totally hassle free.

It comes in two sizes 
SIZE: 1.7 oz/ 50 mL
SIZE: 2.5 oz/ 75 mL


First off I would let you guys know that I'm a fan of Vitamin C cause as someone with sensitive and acne prone skin I tend to have lots of discoloration caused by acne scares. I find vitamin C very effective to fade out my discoloration and make my skin looks more even and brighter. Now coming back to this new 12.5% Vitamin C serum from Kiehl's, I would say I'm stoked! After giving it a try for a good one week + I can already see it help to fade off my previous acne scars, although I'm currently still experiencing active break outs but this vitamin C serum didn't cause any more irritation but instead it helps to calm down my redness and make my skin look more even. I love incorporating vitamin C into my skincare because I can always feel my skin become more supple, soft and refine my skin texture. Not to forget my skin looks much brighter and even :) So happy with this new  Kiehl's - Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C. 

A few weeks back due to my hectic work and schedules and of course unbalanced lifestyle and sleeping pattern I started noticing little visible lines on my skin :( which was totally shocking for me! Who want's to age right? Not that I fear aging but I believe we should start early prevention on it. That's why I was so happy when this product's main use is to fight fine lines and after continuously using it I do notice change but I know result won't show instantly for fine lines and wrinkles that shy I have to give it more time to say more on this issue but as it evens out my skin I can see the lines starts to fade even though not fully yet. 

I usually like to use this after toner as a serum step day time and evening and then continue with my moisturizer. Since Vitamin C is high in anti oxidant and acidic you need to make sure to use sunscreen always cause this will help prevent further problems. Make sure to avoid eyes area :) Pat a tiny pump for your whole face and neck area and gently massage the product. 

You can now find this new 12.5% Vitamin C serum product from Kiehl's at all Kiehl's counters at department store and Kiehl's boutique all across Indonesia. Hope you find this post useful and thank you for reading, see you on my next one!  

Love, Stevie
