The best
This is the best vitamin a serum I’ve used. Although a strong percentage, this formula is very gentle and my skin loves it!

Great customer service
I'm very impressed with DRSQ customer service. When I queried a missing item from my initial order, they replied promptly, sent the item by express post which I received the next day and even included a complimentary gift. I've yet to try the products, but I wanted to give prompt positive feedback about their customer service.

Love this Serum
I have been using DRSQ for about 18 months now including this serum. I believe my skin has overall visibly improved; it is definitely smoother and more radiant. Not only is DRSQ very transparent with their ingredients but they also provide excellent customer service and take care of loyal customers. I have made the change from a high end beauty brand to DRSQ and there is no going back. Thank you DRSQ.
