I have enjoyed using this pack from Essano. I am an Essano fan, and with the exception of the rosehip scent of some of the products, generally find them of superior quality.
The day creme is thick and creamy and very nice for firming and hydrating, more so than most cream moisturisers, and the scent is rosehip but not too strong. The night cream is smooth and creamy and doesn't have a scent. which is ideal. I like how soft and hydrating it is. The overnight mask is pretty similar to the night creme so pretty average for me, though it works well, it wasn't as good as I expected from a night mask. I'm not convinced that you need both, is my point. The facial oil is the real star of the show, I love it. it is very firming, plumping and hydrating and I'd happily buy it alone and use it every day.
Overall a lovely pack to try, but when buying full sized products I'd probably use 2 or 3 of them rather than all 4. I definitely recommend buying the pack to try them and pick your favs.
I like this brand because of the natural ingredients in its products and also it is a New Zealand brand. I have had a couple of these handy packs, gifted one and they are great for travelling as well. All of the Essano Collagen range is really good, especially the Collagen Boost Facial Oil.
