Hi there,
Thank you for your review and we are sorry to hear about this!
Unfortunately, hyperpigmentation is one of the trickiest skin issues to treat and the longer it has existed on your skin, the longer it will take to see improvements and three weeks of applying the serum may not be enough time. A lot of our customers experience a reduction in their hyperpigmentation within a few weeks of applying Sevenly Delight, but for others it may take a few months to see results. Other factors like the severity of the hyperpigmentation and your genetics will also impact how quickly you see results. Our biggest tip is to be consistent with using Sevenly Delight and your skin will be more even!
For any questions or concerns, please feel free to reach out to us on hello@456skin.com.
Warm regards,
The 4.5.6 Skin Team
