Readers Who Saw Brighter, More Even Skin

Kelly, 24

Skin Type: Normal, dry, combination-oily Skin Concerns: Dull skin, uneven skin tone, hyperpigmentation, dark spots

Brighter skin, more even skin tone, and lighter spots

I’ve never been into serum layering because it always felt like nothing really worked for me. I didn’t have much hope when I first started using the But Better Serum, but after seeing my own before-and-after pictures, I was genuinely surprised.

My skin looks noticeably brighter now and I’m very satisfied with how it feels and looks. Plus, I also love the refreshing scent and watery texture of the serum—it absorbs so well without feeling sticky or heavy.

Within a week, I noticed my skin feeling softer and more hydrated. By the second week, there was a visible reduction in dark spots and uneven tone, and my overall skin radiance had improved significantly. It truly works well, and I’m glad I gave it a chance.

Ee Teng, 24

Skin Type: Combination-oily, sensitive skin Skin Concerns: Dull skin, uneven skin tone

Reduced redness, more even skin tone, brighter complexion

I usually skip serum layering because the more products I use, the oilier my skin gets, and that often leads to breakouts. But the unique packaging of this dual serum caught my eye, and since it doesn’t have a strong scent, I felt comfortable giving it a try.

And I’m really glad I did. It feels very hydrating and lightweight, without any stickiness—something I always look for in a product. After using it consistently, my skin feels deeply moisturised but not greasy. There is a clear glow and it appears brighter and more radiant than before.

My pigmentation has lightened, my pores aren’t clogged, and my skin feels more nourished and less dull overall. Compared to other serums I’ve tried, this one actually showed visible improvements in hydration and brightness.

I absolutely love this product, it lives up to its name. I’m very satisfied and will definitely continue using it until I finish the bottle.

Samantha, 25

Skin Type: Combination-dry, oily T-zone Skin Concerns: Dull skin, hyperpigmentation, dark spots

Brighter, more even skin tone, skin is more hydrated and less oily

This serum’s watery consistency makes it super easy to apply and ideal for layering, especially since it’s not too thick or greasy. Compared to other serums in the same price range, it absorbs much faster, thanks to its lightweight texture.

After the very first application, I was shocked at how significantly brighter my skin looked the next morning.

I usually wake up with dull, yellow-toned skin, especially after sleeping late or eating sugary food, but after using this serum, I woke up with a radiant, bright complexion, even after sleeping at 4am. My face also felt less oily than usual, which was a nice bonus.

Over time, I noticed visible improvement in hyperpigmentation and a more even skin tone. It’s super effective at brightening dull skin, and honestly, I wasn’t expecting much since I’ve tried so many other brightening serums, including big-name brands that didn’t give me the same results.

What makes this serum stand out is its dual combination of vitamin C and niacinamide, which gives it that extra boost in performance.

Zi Wei, 26

Skin Type: Combination-oily Skin Concerns: Uneven skin tone, hyperpigmentation, dark spots

Boost in hydration, skin brightness is maintained

This product doesn’t clog my pores and is really fuss-free to use—even when I’m in a rush. I like that it’s a 2-in-1 serum, which makes it super easy to apply. It’s lightweight, absorbs easily into the skin, and works well under makeup.

After one week, I noticed a boost in hydration, and the serum has helped maintain my skin’s brightness. While it’s effective for keeping my skin moisturised and radiant, it may take more time to see visible results in fading dark spots and hyperpigmentation.

Candy, 33

Skin Type: Combination-dry Skin Concerns: Dull skin, uneven skin tone

Brighter complexion and more even skin tone

The scent of this serum is a refreshing citrusy orange, which I really enjoy. When pumped out, the dual serum feels rich in texture, but surprisingly, it doesn’t feel heavy on the skin. It absorbs well and feels comfortable upon application.

After one week, I noticed a slight improvement in skin hydration and radiance. I also love the dual serum combination—it makes my skincare routine easier and faster. The blend of vitamin C and niacinamide in one serum is especially great for targeting my dull and uneven skin tone.

With continued use, I’m hoping to see even brighter and clearer results over time.

Jia Ning, 19

Skin Type: Oily, combination-oily Skin Concerns: Uneven skin tone, dark spots, acne-prone skin

I was really interested to see how the two serums would work together. After just a single use, my skin already looked more hydrated. It felt noticeably more moisturised, and I liked the results even more with consistent application.

The serum was easy to apply and worked well with my routine. Although I didn’t notice much improvement at the start, the difference became obvious when I compared my skin after three weeks.

My skin now feels deeply hydrated, looks visibly brighter, and has a more even tone. I’m really happy with how it turned out.

Readers Who Noticed Faded Dark Spots & Pigmentation

Erika, 39

Skin Type: Combination-oily Skin Concerns: Dull skin, uneven skin tone, hyperpigmentation, dark spots

Better skin texture, lightened dark spots

Honestly, I was sceptical at first. I’ve tried so many products to lighten my dark spots, and most didn’t work. Still, I decided to give the But Better Brighter Beginnings Vitamin C + Niacinamide Dual Serum a try because I figured there was no harm in giving it a shot.

My first impression was that the serum had a noticeably lighter texture compared to others I’ve used—it felt breathable and comfortable on the skin. Its dual-action formula is definitely a plus, combining vitamin C and niacinamide in one step. This simplified my routine and removed the guesswork of layering.

After the first week, I experienced some breakouts, likely due to my skin adjusting, but I also noticed that my skin felt softer and looked more supple. By the second week, my complexion appeared more radiant, especially in the mornings.

After 21 days, I saw a clear change in my skin tone—my dark spots had lightened, though not completely faded. My skin texture also improved noticeably, and the overall radiance was much better than before.

In terms of effectiveness, I’d say it delivered satisfactory results. It’s a solid addition to a simple, effective skincare routine.

Hazel, 40

Skin Type: Dry, sensitive skin Skin Concerns: Dull skin, uneven skin tone, hyperpigmentation, dark spots

Smoother, brighter skin, lightened pigmentation, skin looks healthier

I love the light, fresh scent of the But Better Serum. The texture is lightweight and watery, which makes it absorb quickly and layer easily with the rest of my routine. Compared to other brands which feel slightly thicker, this one feels much fresher on the skin.

After using it consistently for three weeks, my skin feels more hydrated and noticeably more even-toned. Redness has reduced, and my complexion looks brighter overall. It’s gentle, non-irritating, and didn’t cause any breakouts, which I really appreciate.

The dual pump design is also a nice touch—unique but very easy to use. Overall, I’m satisfied with the results and will definitely continue using this serum.

Lindsey, 34

Skin Type: Combination-oily Skin Concerns: Uneven skin tone, hyperpigmentation, dark spots

Brighter complexion, reduced in pigmentation

Compared to other vitamin C serums I’ve used, which often sting or irritate my skin, this one is incredibly gentle. It glides on effortlessly and absorbs well without leaving any sticky or oily residue, which I really appreciate.

I was initially sceptical that a serum could visibly improve my pigmentation issues, like dark spots from sun damage and acne scars.

After using it consistently twice a day, I noticed visible improvement: my pigmentation appeared lighter, my skin tone looked more even, and my complexion looked more radiant and hydrated—without feeling oily.

The serum has a very light and pleasant scent and the pump dispenser makes the packaging super convenient and hygienic. I really like that I don’t have to manually mix two serums—it’s all in one. One full pump is enough for my face, and I usually pat the remainder onto my neck.

I’m honestly quite impressed and look forward to making this a staple in my skincare routine.

Joyce, 38

Skin Type: Combination-oily Skin Concerns: Dull skin, uneven skin tone, hyperpigmentation, dark spots

Less oily, more brighter complexion

My first impression of the But Better Brighter Beginnings serum was that the packaging looked really good. I honestly thought it would be very expensive since it’s like having two products in one container.

It’s very easy to use and doesn’t feel sticky on the skin. Even when I accidentally pump out too much, it still absorbs easily.

After just one week, I noticed a decrease in bumps, and my skin looked more hydrated and brighter. I also saw that some of my dark spots had faded.

One thing I really appreciate is that I don’t need to layer niacinamide and vitamin C separately; it’s all in one application, which makes my routine faster and simpler.

Compared to other serums I’ve tried, this one stands out for being non-sticky, lightweight, and easily absorbed. Since I started using it, I’ve definitely noticed a difference in my skin condition—it looks smoother, brighter, and some of my pigmentation has lightened.
