I have been using it
[This review was collected as part of a promotion.] I have been using it for 3 weeks only, so its hard to say. It does feel nice and my skin looks good, so I believe it does the job.

Product is worth it!
[This review was collected as part of a promotion.] I have been using it around twice a day, I use it after my cleanser in the morning and noticed my dark spots are reduced and my skin feels smooth with this too! I do wish they had a bigger product for this

As described
[This review was collected as part of a promotion.] This product leaves the skin smoother and more firm without stripping moisture. A great addition to a multi step routine with moisturiser.

I am happy
[This review was collected as part of a promotion.] I like the serum's lightweight texture; it doesn't feel heavy on the skin after application. It leaves the skin feeling moisturized and well-cared-for. I will definitely buy it again.

Excellent product shame about the bottle
The product itself is really good and I have no complaints about its performance. However, the bottle and pump could definitely be improved. The product tends to dry inside the pump and become crusty, which causes it to block. Even after cleaning it out, the pump can then shoot the product across the room rather than dispensing it properly! This results in quite a lot of wasted product, as well as having to clean whatever happens to be in the line of fire. A different pump or bottle design would make a huge difference as this makes me question buying it again in future.
