Is this retinol serum any good?

Just want some advice and thoughts on this product by Clear Skin Days?

little bit about our retinol: We’ve included a 5% Retinol complex, which contains 0.05% pure retinol which is effective and tolerable for most skin types. We selected our retinol because of its enhanced stability profile, which usually results in a more stable and therefore efficacious product in the long run.

We have used a Cyclosystem Complex in which the retinol is micro-encapsulated in cyclodextrins, protecting it to provide potentiation of its efficiency and controlling its release, prolonging its action time.
