  • IWLT Hydra Extra Concentrate Serum is recommended for normal/dry skin.
  • Suitable for day/night use.
  • 1 bottle can last for about 4 to 6 weeks if used daily.

Hydra Extra Concentrate Serum’s nickname is ‘Sugar Serum’ because of its brownish condensed texture. It provides rich nourishment and moisture, and also helps to restore firmness with its highly condensed solution.

Even though it is a serum, I personally think its texture is closer to ampoule. Highly concentrated with key active ingredients like Niacinamide (brightening), Crithmum Maritimum Callues Culture Filtrate (deep hydration), Adenosine (Wrinkle Care), and Ceramide 3(Skin barrier enhancing). 

You will feel immediate firming effect after this product. So bouncy! So jjonjjonhae jinjja (쫀쫀해 진짜!)

If you are concerned about skin elasticity, this product is the one you have been looking for! 

How to use:
📍Mix with moisturiser to strengthen moisturising power
📍As a booster product before sheet mask
📍For Korean glass skin, try with IWLT glow ampoule
You may find it sticky at first, but after applying, it absorbs well into your skin due to your skin’s temperature.


Toner > Treatment ( essence, ampoule, serum) > eye care > moisturizer > sun care

Both Ampoule and Serum belongs to treatment stage which you use after toner and before moisturiser. In treatment stage, you are supposed to use key product to address to your main skin concern(brightening? wrinkle care? firming? pore? trouble?).

  • IWLT concentrate serum : Firming & Skin texture focus /+ wrinkle care & brightening
  • IWLT all in one ampoule : Brightening focus/ + wrinkle care & soothing & moisturizing

If you skin is dry or normal skin you can layer both products at once (Iwlt ampoule > Iwlt serum, since serum texture is thicker).

But if your skin is oily or combination skin, applying too much treatment products (too much nutrition at once) will only cause you more skin troubles and break out. What you can do is alternate the treatment products like Day and Night or try different product after finishing your current treatment product.

For my personal case, my skin is combi skin, so I don't apply glow ampoule and serum at once. Usually I alternate day(all in one glow ampoule) and night(serum) or sometimes use them in different days(I am currently using bebetox ampoule for pore tightening too so). But if I go to Korea, I use both products at once, since Korea is so so dry except summer time. 

So it all depends on your skin type and environment! If you are not sure, feel free to ask us anytime at help@ksisters.sg
