Good hydration but didn’t notice a change in wrinkles. Lightweight, absorbs quickly without residue. Happy so far and will continue using.
Greta from Berlin, Germany –
Not bad for sensitive skin. Light texture, absorbs quick and feels hydrating. Slight scent but fades fast. Used two weeks, some redness improved.
Elara from Phoenix, USA –
Used it daily. Absorbs quickly, no sticky residue. Makes skin smoother without irritation. Solid for sensitive areas too.

التون أفضل لترطيب البشرة. حسيت بحكة بسيطة بعدها، بس مو كلي حلو للترطيب العميق.

I’ve been using this serum for about two weeks. It hydrates pretty well and absorbs quickly, which I like. The scent is subtle but pleasant enough. Shipping was a bit slower than expected, took nearly ten days to arrive here in Seattle.

FIRSTLAB Probiotic Serum Review
My skin has been feeling rough and losing elasticity lately, so I was looking for a product that could take care of moisture, brightening, and wrinkle improvement all at once, and I tried FIRSTLAB Probiotic Serum.
First of all, the container looks premium! The semi-transparent glass bottle is clean, and the dropper type allows for hygienic use. The texture is a milky-white serum that is slightly thin but has consistency. When placed on the back of the hand, it spreads smoothly and absorbs quickly without stickiness.
The scent is almost fragrance-free, so it was comfortable without irritation. After applying, a moisturizing glow appears on the skin and elasticity is felt. After using it for a few days, the skin texture became much smoother and the inner dryness was greatly reduced.
PROS SUMMARY:
– Fast absorption, almost no stickiness
– Gentle formula with no irritation
– Improves inner dryness and elasticity
RECOMMENDED FOR:
– Dry or sensitive skin
– Those concerned about inner dryness and loss of elasticity
– Those looking for a reasonably priced serum
Overall rating: Skin becomes smoother and firmer with consistent use! I trust Ildong products so I feel safe using it. 100% repurchase intention!

At first, I bought it because of the trust the keyword probiotic gives.
My skin has been getting sensitive easily lately and dryness has been increasing suddenly, so I was looking for a serum without irritation. Especially as the seasonal transition started, my cheekbones became red and irritated, and the pore areas felt slightly rough, so I wanted to try a calming + barrier care product.
The serum texture is not too thin or too thick – a medium viscosity lotion type. When placed on the back of the hand, it does not run but spreads smoothly on the skin when applied.
What I was most satisfied with was that there was no irritation. Usually when my skin is sensitive, new products cause immediate stinging, but this serum had almost no such reaction. Rather, the reddened areas were subtly calmed the next day.
Highly recommended for those with sensitive or dull skin looking for a gentle, barrier-strengthening serum!

My skin started looking dull one day, and makeup was not applying well. So I decided to change my basics and tried FIRSTLAB serum.
The first thing I noticed when applying it was that the texture is lighter than expected. It feels like a thin essence but absorbs quickly into the skin. It finishes moisturized without stickiness, so it is easy to use in the morning without feeling heavy.
APPLICATION AND ABSORPTION:
– Spreads lightly like water
– No pilling even when layering twice
– After absorption, skin feels deeply moisturized
Rather than just surface hydration, it feels like moisture filling from within, which was especially satisfying when my skin was dry.
When used consistently for 2-3 weeks, the skin texture becomes refined and reflects light well. That is why it looks brighter. Highly recommend for dull or dry skin!

My skin has been dry and sensitive lately, feeling tight and breaking out easily no matter what skincare I used. After using FIRSTLAB Probiotic Serum, my skin has definitely become more stable and my skin texture has improved. The serum has a probiotic-based formula that helps strengthen the skin barrier and reduce sensitivity. It absorbs well without stickiness and provides long-lasting moisture. Highly recommended for those with dry or sensitive skin!

I wrote this review after receiving the product for free through the Coupang trial event.
Recently, I was exercising while exposed to sunlight, and even though I applied sunscreen, I was sweating and got exposed to UV rays. I started noticing spots and melasma that were not there before. Even with makeup, they would not cover and my skin looked dull, so before going to the dermatologist, I wanted to try improving my skin with skincare products.
FIRSTLAB Ildong Pharmaceutical Probiotic Serum has been great for my skin concerns. The texture is moisturizing with a slight viscosity, but it absorbs quickly without feeling sticky. My skin feels hydrated and more even-toned after consistent use.
