Great serum

I am 46 years old and experiences early menopause.

Perimenopausal symptoms started around my 40 so my skin lost elasticity and firmness.

Theorem Serum Bust makes my skin looks and feels well hydrated, rested, fresh and firmer. I tried some more expensive and well known skin brand but T.B.S works much better for me.

I am hoping “Caire beauty” will develop their own face moisturizer to use with this serum

First time user

Applies on smooth and light. With such a large bottle I won't skimp on applying. My snaggle tooth wrinkle is smoothing out!

Love this serum!

I have a very dry skin and since I started using the serum, my skin has become much more moist and supple. I use the recommended amount and it is sufficient for my face, neck and chest. I'm very glad I found this product!

I have been using this serum for about a year. I use it twice a day.It keeps my face and neck more firm and hydrated.I am well past menopause at 77.I wouldn't be without it.

My 96 year old Mother uses it as well and loves it.
