A little goes a long way
This product is fantastic. It was recommended by a friend. Although this product is marketed for women, I can 1000% vouch that it works brilliantly on men's skin too. My skin looks and feels fresher. It is tighter and constantly looks hydrated. The product itself is silky to the touch but leaves no residue on your skin. It absorbs in about 10 seconds. A little goes a long way with this product too, 2 squirts covers my entire face and neck. Brilliant, quality product that I would highly recommend. Thank you 👌

Lovely product
Absolutely love this product line I have the retinol serum, the vitamin C serum and the hyaluronic acid gel cream. I use them all interchangeably and I have noticed a decrease in my rosacea. Although the redness and bumps haven’t completely gone, my skin definitely looks better and healthier. All the products are really gentle and smell divine. So glad I came across this small business. They should really be more well known for their quality of product. Thank you!!

Definitely recommend
I really like TSU:SEI Vitamin C Serum. It's light, non-greasy, and keeps my skin hydrated. The MAP helps brighten my skin and reduce dark spots. It works well as a makeup primer too. Definitely recommend!

It was ok
I bought this because I liked that the vitamin c and hyaluronic acid were combined. It looked like it would be really fancy but the packaging wasn't great. The dropper detached from the lid on the first day and although the serum seemed to be ok, I've had better. You get what you pay for really.

Simply beautiful products ❤️
I don't generally follow a skincare routine, but I thought I'd give these a go and now I just want to use them all! These feel so amazing, and made my skin look fresh and healthy literally overnight. The tone and balance has been restored, my fine lines reduced, and I feel more youthful. Would definitely recommend 👍🏻 and will continue to purchase... Such value for money and they look so pretty too! Thank you TSU:SEI ☺️

favourite serum
My favourite vitamin c serum, my skin loves it. Its lightweight texture absorbed quickly into my skin, leaving it feeling refreshed and hydrated. After a few weeks of regular use, I noticed a visible improvement in my skin’s brightness and overall tone.
