Introduction

ampm is a Taiwanese cosmeceutical brand under the Naruko product line. While Naruko specializes in acne-prone skin, ampm focuses on brightening, hydration, soothing, and dark spot correction. This ampm Brightening & Dark Spot Correcting Serum, in particular, is designed for high-efficiency brightening and dark spot reduction. It has a refreshing texture but still offers good hydration, thanks to added hyaluronic acid and vitamin B5, which enhance skin barrier repair, boost moisture, and improve radiance.

The ampm 2% α Arbutin VC Spot Essence contains the following ingredients for brightening, dark spot correction, and skin tone improvement: 
*   2% α-Arbutin: Low irritation, inhibits tyrosinase activity, and reduces melanin formation.
*   Patented Ethyl Vitamin C: Inhibits spot formation, lightens melanin, and offers excellent anti-aging benefits.
*   Cherry Leaf Extract: Contains cherry leaf flavonoids for skin-softening and plumping effects.
*   Vitamin B3 (Niacinamide): Promotes skin vitality and evens out skin tone.

#Arbutin + Vitamin C for precise brightening and dark spot correction

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

Ita previously used ampm products, but with changing skin needs, this time she chose ampm 2% α Arbutin VC Spot Essence, hoping to improve the sun spots on her face.

The pink bottle and pink serum have a light minty scent, possibly from cherry leaf extract. It feels slightly cool on the face, with a very watery texture that absorbs quickly. However, the moisturizing effect doesn't last long, so you need to apply lotion immediately after use.

After two weeks of using this brightening and dark spot correcting serum, the experimental group's right elbow showed slight brightening, but the overall brightening effect was somewhat weak. Since the ingredients are slightly irritating, those with sensitive skin might want to consider carefully. 
*   Pros: Good brightening effect
*   Cons: Slightly irritating ingredients, low moisturizing power

#A large-capacity medical-grade Brightening & Dark Spot Correcting Serum with a noticeable fragrance

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

L'ameille's Brightening & Dark Spot Correcting Serum comes in truly stunning packaging—a shimmery, high-end pink and white gloss.

With a generous 60ml capacity, I found myself wanting to use a bit more each time, extending it to my neck for extra care. The pump dispenser is unique, a premium version of a dropper, though the large dropper size made it easy to dispense too much.

In terms of scent, L'ameille is the most fragrant of the 10 products reviewed here, with a somewhat rich aroma. The serum's texture is, as described on its official website, a micro-emulsion. It takes a little longer to absorb into the skin, but its moisturizing effect is quite good.

Overall, it's a decent product. After using this L'ameille serum for a week, my skin felt noticeably brighter and smoother. I also tested it on my left elbow, where it improved the appearance of dullness. However, the ingredients are a bit complex, so I recommend it for those with less sensitive skin. 
*   Pros: Large capacity, lasts a long time
*   Cons: Stronger fragrance

#Highly moisturizing Brightening & Dark Spot Correcting Serum

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

For Beloved One's Brightening & Dark Spot Correcting Serum comes in a cute, compact bottle that dispenses just the right amount with each pump. Its texture is a light emulsion that feels refreshing and absorbs quickly, leaving skin well-hydrated, firm, and smooth.

As for the scent, because no added fragrances are used, it has a natural, raw skincare ingredient aroma.

After two weeks of using this Brightening & Dark Spot Correcting Serum, reviewer Itata noticed a clear brightening effect on her skin, though the dark spot correcting results were not as pronounced. For enhanced brightening, consider the brand's Ethyl Vitamin C Whitening Serum, which is in a slightly higher price range. 
*   Pros: Easy-to-use pump bottle, excellent hydration, good brightening effect
*   Cons: Average dark spot correcting results

## Neogence Extremely Luminous Whitening Spot Essence 霓淨思｜極透光亮白淡斑精華

PLATE 04–03

### 霓淨思｜極透光亮白淡斑精華 About the Venue

*   Salicylic Acid: Inhibits melanin cell production and improves hyperpigmentation.

#Antioxidant, highly moisturizing serum for sensitive skin

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

Neogence Extremely Luminous Whitening Spot Essence comes in packaging very similar to Kiehl's, with a clear bottle and serum. The texture is quite thick, requiring some massage for the skin to fully absorb it, but the skin remains very moisturized for at least ten minutes after application.

The serum is virtually odorless and causes no irritation upon application, aligning with the brand's core philosophy of being hypoallergenic and non-irritating.

After two weeks of using this brightening serum, Itata noticed significant "brightening" of her skin, though the whitening and dark spot correcting effects were less pronounced. This might be because the serum primarily contains antioxidant ingredients, suggesting it may require more time to show full results.

However, there was no allergic reaction during use, making this brightening serum a good recommendation for those with sensitive skin or anyone looking to brighten their complexion. 
*   Pros: Excellent brightening effect, non-irritating ingredients, suitable for sensitive skin
*   Cons: Ineffective for dark spots

#Dermatologist-grade Brightening & Dark Spot Correcting Serum for Hydration and Whitening

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

The Jealousness Vitamin C Whitening Serum bottle is beautiful, with an ivory-white to clear glass gradient that gives it a premium look. It features a convenient pump dropper, and the serum has a faint, natural scent from its ingredients.

Upon application, I noticed this serum is quite thick, but it spreads easily and absorbs without any stickiness, leaving the skin highly moisturized—a truly surprising effect!

After about two weeks of use, my skin's condition significantly improved, becoming more hydrated and plump, with visible brightening. This is a Brightening & Dark Spot Correcting Serum I would definitely continue using. 
*   Pros: Excellent brightening and hydrating effects.
*   Cons: The dense spherical particles in the bottle might be off-putting to some.

#Fast-acting Brightening & Dark Spot Correcting Serum with Superior Hydration

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

Dr.CINK is a hydrating Brightening & Dark Spot Correcting Serum with excellent spreadability — a tiny drop covers the entire face, though it does need a bit of massage time to absorb. Be careful not to pump out too much at once.

The serum itself has a faint, not particularly pleasant scent, but its moisturizing effect is outstanding. The best part is that this Dr.CINK serum delivers an instant brightening sensation! Itatata applied it to her right wrist for two consecutive weeks, and the skin there genuinely felt softer. When her mother, who has more freckles, tried it, the results were also impressive.

However, the Dr.CINK website is not intuitive to navigate, and a full ingredient list is only available after purchasing the product, which is inconvenient for users and led Itatata to deduct a small point from this medical-grade skincare brand. 
*   Pros: One drop covers the face, excellent moisturizing effect
*   Cons: Not suitable for sensitive skin

Introduction

Dr.Satin is a Taiwanese cosmeceutical brand known for its affordable luxury approach to skincare. Recognizing the nutritional value of caviar and its benefits for skin, the brand leverages advanced biotechnology to incorporate caviar extract into its products, making premium skincare accessible to everyone.

It features caviar extract to repair the skin, while Vitamin C derivatives work to fade melanin and improve dullness. Glycogen and hyaluronic acid act as humectants, providing intense hydration and a rich, moisturized feel.

The Dr.Satin Caviar Dark Spot Essence includes the following ingredients for brightening and dark spot correction: 
*   Tranexamic acid: Inhibits melanin production, helping to brighten and whiten the skin.
*   Vitamin C derivatives: Powerful antioxidants that revitalize dull skin, improve hyperpigmentation, and promote brightening and whitening.
*   Mulberry bark extract: A natural, low-irritation botanical extract that combats UV damage, inhibits melanin formation, and reduces skin dullness.
*   Vitamin B3 (Niacinamide): Helps strengthen the skin's protective barrier, reduces moisture loss, and improves dullness for a whitening effect.

#Highly effective Brightening & Dark Spot Correcting Serum recommendations

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

Dr.Satin Caviar Dark Spot Essence comes in a soft tube, unlike other serums, so you can squeeze out every last drop without waste.

This serum is a pale yellow with a subtle fragrance. It's incredibly moisturizing, delivering an instant brightening effect upon application, and its hydration lasts a long time.

After two weeks of using this Brightening & Dark Spot Correcting Serum, Etata saw significant improvement in her skin, and the brightening and dark spot correcting effects were excellent. Even Etata's mother, who has many freckles, found it very effective and loved the texture and results of Dr.Satin.

#Cosmeceutical Serums for Brightening & Repair

REVIEWED BY [伊塔塔](https://www.twosevenths.com/en/tag/%E4%BC%8A%E5%A1%94%E5%A1%94/)

Dr. Wu Resveratrol Brightening Repair Essence has a light, watery texture that spreads easily and absorbs quickly; however, its moisturizing effect is also short-lived. After about three minutes, my dry skin felt parched and a bit tight again.

Since this serum contains no added fragrances or other sensitizers, it has the natural scent of its raw ingredients. While not unpleasant, a milder fragrance would enhance the user experience.

After about two weeks of using this Dr. Wu Brightening & Dark Spot Correcting Serum, I didn't notice significant brightening. For enhanced brightening effects, I would recommend their Ultra-C series instead. 
*   Pros: Free of irritants, preservatives, and fragrances
*   Cons: Less effective at moisturizing
