The review highlights the product's excellent absorption and attractive packaging. However, the user expresses concerns about the texture, preferring a thicker consistency. They're uncertain about its effectiveness in providing hydration.

The product's consistency is too thin. I wish it had more viscosity. I'm not sure about its hydrating effects.

It absorbs well into the skin. The design is beautiful, and I love that it's made of glass.

One Thing Niacinamide Glutathione Serum 50ml

The new whitening serum from One Thing

Containing 50,000ppm of niacinamide,
it helps with whitening effects and
inhibits the transfer of melanin pigment.


✔️ Concerns about freckles and blemishes (gently cares for blemishes)
✔️ Skin tone concerns

It absorbs quickly without stickiness
and is fragrance-free, which I really liked.

There isn't really anything. If I had to pick something, it would be the price, but even the price isn't that bad in my opinion.

It's always reliable and used.
The freckles have started to fade, and I've started to see my skin brightening up.
While it may not be dramatic, I can feel my skin becoming more radiant.
The freckles may not be 100% improved, but I'll keep applying it diligently.
I've been using it for about 2 weeks, and I haven't experienced any breakouts or issues.

It has a slightly sticky and yellow texture, so my face looks a bit yellow after application. But it's fine since I can just apply makeup over it.

Collagen-boosting ingredients niacinamide and glutathione. If you apply sunscreen well, it would be good to apply it in the morning as well.

The whitening product was moisturizing, but if you feel your skin is dry, applying a bit more cream will not cause any irritation at all.

There didn't seem to be any particular shortcomings.
I was overall satisfied.

Skin tone improvement, reduction in pigmentation, triple skin tone improvement, soothing care and moisturizing - it's so great for daily skincare!
And I personally think the One Thing Glutathione Spot Serum can easily provide home care that adds vitality to tired summer skin and helps cultivate healthy skin.

Perhaps you dislike the oily style! If you don't like the shiny look, you probably won't like it!^^ I like it - my skin feels like the tone is balanced after 2 weeks ^^

These days, when the weather is so changeable, my skin also becomes sensitive and dull.
Whenever I look in the mirror, my freckles and blemishes seem more prominent, which has been a concern of mine.
That's when I came across the One Thing Niacinamide Glutathione Serum.

At first, I thought it was just another whitening serum, but after using it for about 7 days, I noticed that my skin texture had become noticeably smoother, and my complexion had brightened.
Most importantly, it has a non-sticky, moisturizing, and refreshing finish, so I can apply my makeup right after using it without any issues.

With 7 different vitamin ingredients, it nourishes the skin, and the subtle glow it maintains throughout the day is truly satisfying.
If you're struggling with blemishes, freckles, and dull skin tone, I highly recommend giving this a try.

My skin has become much brighter, and I'm happy to see my face in the mirror again.

Apply 1-2 drops to areas needing intensive care and gently pat to absorb.

It's too early to confirm the effects after short-term use, but I'm hoping for noticeable results.

The One Thing / Niacinamide Glutathione Serum

Containing niacinamide, which helps inhibit melanin pigment transfer, this serum aids in brightening effects.

When applied to the face, it absorbs quickly without any stickiness, making it perfect for hot summer use.

The vitamin ingredients give your skin a glow, while tea tree extract soothes the skin. It seems to solve everything you want in one product!

It was excellent for my blemishes. This might be the best product I've tried.

Absorbs wonderfully and sinks in beautifully. I'm really satisfied with it!

There wasn't anything particularly bad. It's generally good and effective for brightening and blemish care.

My skin is thin, sensitive, and combination dehydrated! 

The texture is light and fluid, absorbing gently into the skin. It feels refreshing without any stickiness or heaviness, which I really like. I think it would be suitable even for those with thin, combination dehydrated skin like mine.

I was hoping for brightening and clarity effects, and after using it for a few days, I can definitely see that my skin doesn't look dull and my complexion appears more even. In the morning when I apply makeup, my skin texture feels smoother, allowing my base makeup to adhere better.

I'd recommend this to anyone who, like me, has been feeling their skin looks dull or lacks vitality.
