I really love this product but would urge caution when sealing the bottle as I managed to lose a third of the contents

Fantastic product

Originally posted on ESPA

Product is excellent, only slight downfall is the lid/pipette push top. In comparison to the rest of the product and the quality, this feels very cheap and does not reflect the premium nature of the brand or product

Excellent serum

Yes, I recommend this

I had purchased this booster serum in the past. A little goes a long way as I mix it with my normal cream at night. On me, I can really see the difference in the morning. I don't use every night maybe 2-3 times a week.

Fab!

Originally posted on ESPA

A friend gave me a sample bottle and I absolutely loved it. I then purchased a full bottle and will never ever use anything else in the future. I am 65 and have quite good skin for my age as I have always looked after it, but this has taken my skin to a whole new level, and now my daughter who is in her 30's uses it and loved it.

Great cleanser, not great serum and moisturizer

Originally posted on ESPA

Yes, I recommend this

Cleanser is great, but the serum and moisturizer have a strong unpleasant odor.

Thank you for your review for the Glow From Within Facial set. We're happy to hear that you like the cleanser however, it is a shame that you do not like the smell coming from the serum and moisturiser. We have contacted you asking for further information to see if we need to look into this!

Bought this after using it from a Christmas gift set. Really like how it glides into my skin. It’s light and my skin feels great. It’s now part of my daily routine.

Dissapointed

Originally posted on ESPA

I was gifted a bottle of the on a Ritz Carlton cruise and loved it - the smell, fragrance, and the feel of the serum. The two bottles that I ordered from you have the same nice feel to the serum but no fragrance at all. I am wondering if I was sold very old bottles perhaps expired.

Thank you for your review, and for being a fan of our products since your Ritz Carlton cruise. We are very concerned and sincerely sorry to hear that the two bottles you ordered from us did not have the fragrance you know and love. I have reached out to you via your account, so we can investigate further.

The magic serum

Originally posted on ESPA

Yes, I recommend this

[This review was collected as part of a promotion.] This serum is absolutely amazing, my skin adores the moment it touches it, I find gently rubbing the oil in between your hands and gently pressing the oil onto your skin rather than rubbing into the skin you reap the benefits more plus the serum goes more of a long way
