My newest addition, the Thank You Farmer True Water Deep Serum EX*, is a hydrating, anti-aging serum from the K-Beauty skincare brand Thank You Farmer. I haven’t tried anything else from Thank You Farmer yet, but my fellow muse, Mia, has been enjoying the Thank You Farmer Miracle Age Repair Toner.
What is your favorite part of your skincare routine? Mine is serum! Before exploring skincare, I had nil idea what serums were. In case you’re in that stage, facial serums are highly concentrated liquids formulated to target a particular skincare issue. There are those intended for acne and dull skin and also for anti-aging.

Since I have this particular fondness for serums, I was delighted when Thank You Farmer gifted me with one of their products: True Water Deep Serum EX!

The Thank You Farmer brand

Thank You Farmer is a Korean brand that imbibes our farmers’ concept of natural and farm-grown ingredients.
The brand does not promise rapid results, but through time, patience, and efficacy of its products, it will lead to bright, resilient, healthy skin.

True Water Deep Serum claims

Thank You Farmer True Water Deep Serum is an anti-wrinkle and brightening skincare product that works by sustaining moisture deeply into the skin. It is stated to be suitable for all skin types.

The serum was created with skin-fit technology. This technology helps with the thorough adhesion of the ingredients into the skin as the vegetable mucin has been permeated into a moisturizing factor.

The serum has a water glowing effect as its softly absorbed and creates a moisture barrier. By using a lively essential formula, the serum transforms rough skin into glowing skin. The ideal skin type claimed by the producer is dry.

True Water Deep Serum* comes in a 60 ml / 2.11 fl oz white and light blue bottle. The water droplets on the packaging nourish a sophisticated look.

The container is generous, which makes it suitable for sharing, which I do, with my husband. Depending on your usage, the serum can last for months, making it excellent value for your money.


The Thank You Farmer website boasts it has a:

Signature scent that refreshes your mood. It soothes your mind from the hardships of city life and relaxes you through the citrus scent blending of grapefruit, orange lime and lemon.

Indeed, the Thank You Farmer True Water Deep Serum has a discreet and refreshing scent.


Thank You Farmer True Water Deep Serum Texture

The Thank You Farmer True Water Deep Serum has a unique viscosity due to the addition of Yam Root Extract (Dioscorea Japonica Root Extract). Similar to the snail mucin, the Yam Root has vegetable mucin.

True Water Deep Serum’s texture is notably concentrated, making it viscous and slippery at sight, but it wears off right after application. I also feel that there’s a film applied to my face, which I think is what the brand is saying as a unique texture.

My experience with Thank You Farmer True Water Deep Serum:

I have a normal – combo skin type, and I live in a tropical, humid climate where we don’t have winter, so I don’t know how this serum performs during cold weather.

How to use

  1. After cleaning and toning my face;
  2. I get two pumps from the bottle;
  3. I apply the serum to my face and neck;
  4. I follow with an ampoule, moisturizer, etc.

The Thank You Famer True Water Deep Serum moisturizes my skin without a heavy feeling. The concentration may look thick, but I felt no stuffiness after applying it to my face.

There’s evident radiance on my face when I wake up in the morning. My skin feels softer and healthier.
It minimizes my morning face rash, which I experience almost daily (but disappears throughout the day).
It does not clog my pores, nor does it trigger my eczema.

  • truly hydrating
  • soothes
  • big size for a serum


  • I am leaving this blank because I can’t think of any!


I’m glad I tried this product out. I think I found a solid serum for a person with combination skin. It exceeded my expectations as far as moisture and brightening are concerned. In addition, it’s cruelty-free, paraben-free, sulfate-free, and hypoallergenic.

Will I repurchase Thank You Farmer True Water Deep Serum?

While I did enjoy this product, I will probably not repurchase it because I sometimes enjoy switching things around.

As always, you do you, be kind to your skin and yourself!
Remember that every person’s skin and skin type is different, so what might work for me might not work for you, and vice versa.
So before trying a new product, it pays to do a little research first. Pay special attention to ingredients that you might react to.
Doing a patch test is always a good idea. Unsure? Best to consult your dermatologist.
Happy skin experimenting!
