Reviews Summary
Customers say this lip balm delivers mixed results for hydration, with some finding it deeply moisturizing while others report dryness. Many reviews mention a glossy finish and temporary plumping effect, particularly when used consistently. Common feedback includes concerns about the texture, with some noting graininess or clumps. While several users praise its overnight results, others point out the formula's quick wear-off time. Reviews are divided on the scent and taste, which appears to be a significant factor in user satisfaction.

    I haven’t experienced a dramatic result but I do feel my lips are plumper and I intend to continue using this lip balm to maintain the improvement.

    A waste of money

    Product is unusable due to hard granules in it. I was advised by Injey customer service to rub the tube or product between my hands to dissolve lumps. They are now in the garbage and I wasted my money.

    Don't buy this product.

    Hello Jackie,

    Thank you for taking the time to share your feedback on our Lip Plumping Duo. While we're glad you reached out to our Customer Experience Team about the texture concerns, we're truly sorry to hear that you ultimately had to discard the product. This is certainly not the experience we want for our customers, and we completely understand your frustration. Although some natural separation can occur in our formulations, this should not impact the product's performance or comfort. We take feedback about product texture very seriously as it directly impacts our customers' ability to enjoy our formulations. We truly value your honest assessment as it helps us continuously improve our products and maintain the highest quality standards. We appreciate you bringing this to our attention and sharing your experience with the community 🖤
