Review: Kiehl’s Powerful Strength Line Reducing Concentrate


If you’re looking for a powerful and concentrated serum to tackle fine lines, then you need to try the newly improved Kiehl’s Powerful Strength Line Reducing Concentrate

I’ve been reviewing this magical concentrate from Kiehl’s for about two months now, and I can literally “c” the difference. Ha, see what I did there? Can never resist a good pun.

But seriously though, there’s a reason why one of these puppies sells every minute around the world (over 5 million bottles sold to date).


This powerful, fast acting, anti-aging serum from Kiehl’s has undergone an innovative reformulation to include more Vitamin C (12.5% to be exact) and Hyaluronic Acid. It’s also been clinically demonstrated to provide visible improvement on lines, wrinkles, and radiance.

If you’re a long-time fan of Kiehl’s, you’ll remember the original formula for the Powerful Strength Line Reducing Concentrate has long been a sought-after customer fave. Due to the instability of Vitamin C (particularly at high concentrates), improving the formula was quite a challenge.

But with careful formulation trials and their expertise in working with Vitamin C, Kiehl’s chemists developed a new formula with an even more powerful, clinically-demonstrated performance. The newly improved formula took over approximately 10 months to be finalised, having gone through 89 variations before the final formulation was determined!


As you can see in my ‘before’ photo above, I have some minor fine lines around the corner of my eyes and my forehead.

As I’ve been getting older (turning 28 this year), I’ve noticed more and more fine lines starting to appear around my eyes and forehead, so I was definitely ready to give this product a run for it’s money!


I have been using a small amount (10 cent piece) every night for over 2 months now, and smearing it over my eyes and forehead.

As you can see in the ‘after’ photo above, the appearance of fine lines seen in the ‘before’ photo have been visibly reduced.

What I liked most about this concentrate (besides the fact that it visibly reduced fine lines), is that it instantly leaves my skin looking radiant and smooth. Its perfectly balanced formula allows it to absorb quickly without feeling greasy or oily. It also smells really nice with its citrus scent.

Are you going to give it a try? If so, let me know how it goes for you.
