Below, you can explore specific categories based on global user experiences.

Effectiveness for Puffiness
91%
Many users praise how effectively this serum targets puffiness around the eyes. Consistent use has led to noticeable reductions in swelling, especially after mornings when users tend to feel more puffy. The fast-absorbing formula also ensures it doesn’t feel heavy on the skin during the day.
A few users feel the product’s effectiveness in tackling puffiness could be more pronounced for severe cases. While it works well for minor puffiness, it may not deliver dramatic results for those with chronic or more intense under-eye bags.
Skin Compatibility
89%
Most users with sensitive skin have found this serum to be gentle and well-tolerated. The dermatologically tested formula, free from harsh chemicals, parabens, and sulfates, is a major selling point. It doesn’t cause irritation or redness, even for those prone to skin sensitivity.
However, there are a small number of reviews from individuals who experienced mild irritation, particularly those with extremely reactive skin. A few users mentioned that the serum's light texture still led to occasional dryness in the under-eye area.
Absorption Speed
94%
The serum’s fast-absorbing nature is a standout feature, with many users highlighting how it sinks into the skin almost immediately. This makes it ideal for a quick morning routine, with no greasy residue left behind. It’s particularly appreciated by those who don’t want to wait long before applying makeup or other skincare products.
While most find the absorption quick, some users noted that they needed to apply slightly more product to achieve full coverage, as the serum is very light. A few also felt that the rapid absorption might mean it doesn’t stay on the skin long enough for deeper hydration.
Reduction of Dark Circles
78%
22%
Some users did report improvements in the brightness of their under-eye area, particularly after using this serum consistently for a few weeks. The combination of caffeine and niacinamide appears to help even out skin tone and lighten dark circles for certain users.
However, there were several comments suggesting the reduction in dark circles is not as effective as advertised. Many reviewers felt that while the serum helped with puffiness, it didn’t have a strong impact on stubborn dark circles, especially for those with more pronounced pigmentation.
Gentleness for Sensitive Skin
90%
Users with sensitive skin have found this under-eye treatment to be a gentle option. It doesn’t cause stinging or redness, making it perfect for those who need a calming, non-irritating product. Its soothing ingredients make it a great choice for people with delicate skin around the eyes.
Though generally well-received, a few sensitive skin users noted that the formula’s lightness sometimes left their skin feeling slightly tight. A handful of people also mentioned that they wished the product had a more moisturizing effect to complement its soothing properties.
Non-Greasy Texture
93%
The non-greasy, smooth texture is a highlight for many users who prefer eye serums that don't leave behind a shiny or sticky finish. It’s comfortable to wear throughout the day, even under makeup, and it doesn't disrupt the rest of a skincare or beauty routine.
Some users felt that while the serum is non-greasy, it may be too light for those who need more hydration or emollient properties. This may be a concern for individuals who are looking for a more moisturizing formula during colder months or in drier climates.
Plant-Based Ingredients Quality
85%
The use of bakuchiol as a plant-based alternative to retinol is a key selling point, and many users appreciate its gentle yet effective properties. It’s an attractive option for those looking for natural skincare solutions, and its inclusion in this serum is seen as a positive step for those avoiding synthetic ingredients.
Despite the benefits of bakuchiol, some users expressed that they weren’t fully convinced of its effectiveness in comparison to retinol-based products. A few found that the serum didn’t deliver the same level of skin renewal or anti-aging results they expected from a more potent ingredient.
Brightening Effect
75%
25%
The brightening effect, thanks to ingredients like niacinamide, is noticeable for some users, particularly in the under-eye area. For individuals with mild discoloration or early signs of aging, this serum helps to even out the skin tone and add a subtle radiance.
However, many users with more severe dark circles or hyperpigmentation did not experience significant brightening. Some felt that the product worked better for reducing puffiness rather than delivering lasting brightness to the under-eye area.
Fragrance
82%
18%
The mild, light fragrance of this serum is well-received by users who prefer skincare products without overpowering scents. Its subtle aroma adds to the overall pleasant experience, making it ideal for those sensitive to strong fragrances or who prefer unscented products.
Some users noted that the scent, while not strong, wasn’t entirely to their liking. A small group preferred fragrance-free options, finding even light scents a bit irritating for their delicate under-eye area.
Packaging & Dispensing
87%
The packaging is sleek and functional, with many users appreciating the pump dispenser that ensures controlled product use. It helps maintain hygiene and avoids over-application, which is ideal for those who want to get the right amount of product each time.
A few reviewers mentioned that the dispenser can be tricky to use at times, especially when the product is nearing the end of the bottle. Some felt that it didn’t dispense enough serum per pump, leading to the need for multiple presses to apply the desired amount.
Value for Money
88%
For many users, this serum is considered a good value for the benefits it offers. The 0.67oz size is seen as a reasonable price point, given the high-quality ingredients, such as caffeine, niacinamide, and bakuchiol. The effectiveness in addressing puffiness makes it worth the investment for daily use.
However, some users felt that the product didn’t justify the price for their specific needs. Those who were primarily seeking stronger results for dark circles or fine lines felt it wasn’t as effective as higher-priced alternatives.
Long-Term Results
81%
19%
Many users appreciate the gradual improvements this serum offers over time, especially in terms of reduced puffiness and brighter eyes. The long-term use helps to smooth fine lines and refine the skin’s appearance around the eyes, with some noticing a more refreshed look after a few weeks.
A few users mentioned that the results were not as immediate or pronounced as expected. Some felt the serum’s effects were subtle, and they needed to use it consistently for a longer period before seeing noticeable changes, which might not be ideal for those seeking quicker results.
