I've shopped at Beauty Affairs for a few years now without a problem, however last week my package was stolen- at the fault of the courier. I purchased around $200+ of skincare and was completely devastated when it happened, as I didn't think I would be able to get it resent or refunded because it wasn't Beauty Affair’s fault. I contacted them and to my surprise, they immediately offered to resend or refund my purchase, not only that but they included a gift! I have never had such exceptional customer service from any other company in my whole life! Knowing they are a relatively small (compared to Sephora etc) Australian owned brand makes it even more impressive and I'm so happy (even excited) to know my money is going to a company that highly values its customers. ... MoreI've shopped at Beauty Affairs for a few years now without a problem, however last week my package was stolen- at the fault of the courier.

This serum contains both hyaluronic acid and vitamin B5, and is supposed to caml sensitive or heal damaged skin. Indeed, it does not sting or burn my eczema and dermatitis skin. Being oil free and fragrance free, it suits my sensitive oily acne skin nicely and does not cause any breakouts. Absorbing instantly despite its thick texture, it leaves my skin hydrated, and relatively plump. I strongly recommend that this serum should be used as a second layer after toner. Otherwise, with high concentration of hyaluronic acid and b5, you may feel that your skin is dehydrated. The last step should be moisturizer to lock everything. In short, it works nicely and noticeable results can be seen!

A good serum but.........

I have used this serum for a while now. Good serum to give dry skin a moisture boost especially in the colder months. Absorbs quickly. However this last bottle has changed. The previously colourless liquid now has a colour.......not sure I like that. Also the neck of the bottle has changed. The consistency of the serum seems thinner. Change isn't always good. This was a 5 star serum but now not so sure I'd recommend it.

DOES WHAT IT SAYS ON THE TIN...
6 August 2023

I was shown this product in store as part of a skincare routine overhaul. I'd been using a cheaper brand for a while and while i was happy with that, thought it would be worth trying a HA at a higher price point.Product is good, like the fact the little pipette has measuring doses printed on the side, and there's no real smell to it. Been using this morning and night and my skin does feel and look a little plumper and the fine lines around my eyes aren't quite so noticeable. It's a nice texture - I don't find it sticky at all, unlike some HA's, and the product sinks in very quickly. If you've got the money it's worth a try but think there's lower priced products that do just as good a job,

Fabulous for dry skin
5 February 2023

I was skeptical when my friend told me about this but this product is fabulous. I apply it directly to my skin right after showering and before I moisturize and it keeps your skin hydrated for a very long time. I also use this on the backs of my hands before I put on hand lotion, safe effect (hydrated skin hours longer than with just lotion). Fabulous product with a great velvety texture. A little of this goes a long way so probably the type of thing you only need to buy once a year. Excellent!

My staple serum
29 November 2022

This is the only serum I keep repurchasing for over ten times already. It provides really good hydration. The ingredients are great, no alcohol, propylene glycol or other sort of «untasty» things. I also use it while practicing microcurrents and LED as it doesn’t contain oils so is suitable for these kinds of devices. The serum is neutral so can be used with active serums (retinol, vitamin C, niacinamide, acids). Love it.

Stepping Into Adult Skincare
2 March 2023

Did I turn 40 and mysteriously received three lines on my forehead in the dead of the night? You betcha! 🤣I then stepped into the foreign and very scary adult world of high end skin care products.I love this mini gift set for free with my order. It's so thoughtful and generously received.This is of no fault to Medik8.All their products have high end ingredients at an affordable price.(From my extensive research in finding a dermatologist who breaks down every single ingredient.)Medik8 is making a product that the world is in demand for.My complaint.Hyaluronic acid (sodium hyaluronate) is extremely drying. It literally sucks the water out of the skin so it can pillow puff up the face like a puffer penguin. It shouldn't be put on the face. It makes no sense ... MoreDid I turn 40 and mysteriously received three lines on my forehead in the dead of the night?

The best b5 serum I have tried
27 February 2023

I used to use another expensive medical brand B5 serum, however due to cost I thought I would try this one instead as a little cheaper. I’m so glad I did. The serum is not sticky like the other brand I used to use. Goes on like silk to the skin and keeps me hydrated throughout the day. Just make sure you put on to damp skin to reap the full benefits. My sensitive reactive spot prone skin has had no reaction to this. Have been converted and will definitely repurchase this again.

Unsure if results with Hydr8 B5 Intense
26 April 2023

I was expecting both visible and textural results with daily use of Hydr8 B5 Intense but have not seen either. I’m using it as part of my daily regimen of Crystal Retinal 20 and Crystal Retinal Eye 10, alongside the Advanced Night Restore. My skin looks good. I’m very happy with the other 3 products. This one just doesn’t appear to be doing anything at all. After massaging it in and waiting for it to dry before moving in with other products, my skin feels more taut, not more hydrated.
