The bottle looks tiny but a little bit of this goes a loooong way. One pump worth of this product is enough for my entire face and neck. I used this as part of my 28 day challenge and I think this might have been my favourite product because of how quickly I noticed the change on my skin. Its scent is neutral which I like and its texture is jelly-like and was absorbed quickly by my skin. I also applied it on my lips in the morning and evening, which did wonders for my normally very dry and cracked lips. I got a bit lazy after the challenge and didn't use it for a day and I could already see my lips reverting to the dry look - not good! So I've quickly put it back into my routine. It's a bit pricey but don't let that scare you, it's worth every rand.

Do you ever realize that even if you have diligently applied anti-ageing creams and lotions on your skin to help achieve a youthful looking skin, your skin still appears dull and tired looking? Well, its probably due to “age related dehydration” ARD in short (because we love to sound like experts). It's a condition that many Dermatologists are recently identifying as one of the key contributors to the appearance of aging skin.

Age-Related dehydration is caused by an imbalance of moisture within the skin that occurs as we age, making skin more prone to showing signs of aging sooner. I started having this skin concern several months ago but didn’t realize it was due to ARD.

So to address itI sought to try out Kiehl’s Hydro-Plumping Re-Texturizing Serum Concentrate. The formula in this product is said to help correct the signs of ARD by “flooding” the deepest surface layers of dehydrated skin to restore vital moisture. When skin is hydrated, it will appear more fresh, plump and youthful.

Inspired by Dermatologist who really really care about us :) the serum is formulated with a potent complex of plant-based Glycerin – a natural “moisture magnet” and Shiso Leaf Extract which helps protects the ‘anchoring’ of deep moisture into the skin’s surface layers. Bonus! As many of us know that the technology behind almost all topical products only work as far as the top layer of the skin which in most cases is never enough to bring optimum results. The extract also helps protects against the degradation of the skin’s natural Hyaluronic Acid - (expert alert)

To achieve significant hydration and penetration results, that effectively address ARD, Kiehl’s chemists chose to formulate without waxes, eliminating any barriers, to ensure a more bioavailable preparation when applied on the skin. Second, the formula was developed with an internal water phase that is larger than the external phase to impart an incredibly lightweight texture that ‘bursts’ on application. This internal water phase, which carries the key ingredients – plant-based Glycerin and Shiso Leaf – comprises 85% of the emulsion. On one of my weekly reviews I made mention of the water residue visible upon application. This is the science behind. I had to find it out. It sounds like a lab report but its knowledge is power.

Moving on to information I didn't have to Google.

Its unscented, smooth velvety texture, easily absorbed and extremely hydrating. I love that it acts as an excellent primer. So if you're a primer user, you can enjoy an added benefit with this product. However for this, I'd strongly advise that you start out with a sample first as foundations differ in formulation.

A well formulated serum I have to say and with no alcohol in it, any chances of skin sensitivity were narrowed from zero to none. On one of my weekly updates I mentioned how previously to achieve the same glowy, dewy morning after results, I’d have to guzzle down a litre of water at night time, all in one go. Now with just 2/3 pumps applied on my skin I get the same results in just a few hours.

Definitely a fave, and bravo to the experts behind it.

Say goodbye to ARD and dull fatigued skin, Kiehl it. You'll find it at your nearest Edgars store. (Available at the big Edgar's stores)

The packaging of this serum is a white box that has a blue lining on the top and bottom. When you open on the inside, you get a white 50ml plastic bottle that comes with a pump.

With your first pump you get an, off white almost gel like product that is very lighty fragranced.You just need 2-3pumps to apply to your face and decollette area. The minute you apply the serum you skin can feel the difference because it feels smoother afterward and as you apply its just feels like your skin is drinking water, if that makes sense, but thats how it felt like to me! My skin was smoother and the fine lines and texture was much better than it was before. I think that this serum came at the right time in winter because my skin was dry and was also very dehydrated!

This was my favorite of three products i received to review.
This product comes in a plastic bottle with pump dispenser( I used 2 pumps at a time). Light fragrance not overpowering . Easily absorbed in to my skin. No oily residue was left behind.

On usage on the first day, i already felt the difference in my skin. My skin has never felt so hydrated and amazing. On continuous usage, my fine lines around my eyes appear to be disappearing.

I would love to use this product forever as its really amazing. A bit pricey but so worth every cent. Highly recommended to all.

This serum was my favourite of the three Kiehl's serums which I tested for the 28-day #ChangeYourSkin Challenge. I saw results from this within the first few days of using it. I also loved the pump dispenser which makes it easy to use and keeps the serum airtight and hygienic. This serum is formulated to suit all skin types. It is light and watery on application (with little to no scent) and absorbs quickly without leaving any greasiness on the skin.

What this serum does best is fight dehydration. Even though my skin was combination to oily when I started using it, it was also very dehydrated. The first week I used it I did experience a slight stinging but this went away over time. My skin has felt hydrated and plumped up, my fine lines around my eyes are much less visible and my skin texture is smoother and softer. I also feel that I need far less moisturiser after applying this serum, and don't get any dry patches during the day even when wearing a very matte makeup.

There was nothing about this serum that I didn't love, so I give it five stars for effectiveness and quality. And I would gladly repurchase it when it runs out. The price isn't in the same range as affordable drugstore brands, but it is in line with serums from many other department store brands, and I think it is good value for money.

This has been one of my most favourite Kiehl's serums. Especially in winter, there is just no way one can go wrong with extra hydration. It comes in an opaque pump bottle and one pump is just the right amount of product to cover a full face. The product is immediately absorbed into the skin and leave no residue. Leaves the skin feeling supple and plumped out.
