Dr. LeWinn’s Ultra R4 Collagen Surge Overnight Sleep Mask

I was so excited to have the opportunity to be on the trial for this - thanks so much BR Babes :-)

This is a product that I'm really excited about - really surprised at just how much I love this product.

The bottle it comes in is actually really cool, and I love the fact that it is clear so you can see how much product you've used vs how much is left. I'm quite mesmerised by the fact that both formulas are separate but once you pump the product out, they merge into one and the creamy consistency once you massage them together between your finger tips. I love it.

The application is really nice and luxurious, like you are treating your skin every time you apply it. Its quite magical actually - when you put the mask onto your face it is clear.

The smell is sooooo good. I can't really put my finger on the actual smell but it is a really nice clean perhaps floral scent? Either way it is really nice.

I didn't notice straight away if it was doing anything but after a few uses, noticed that my skin was more hydrated and a lovely radiant glow. Usually I have really dry patches in the creases of my nose, but not since I've been using the mask.

The only down side if you can call it that, is that when you put it on, for awhile it feels quite tacky. But because you put it on and then sleep you just forget about it and you are left with radiant and glowy skin the next day.

I highly recommend this and will definitely purchase once this is finished. Bonus is that this will last for quite awhile, so great value for money.

I found this mask made my skin feel instantly hydrated & soft & over time I noticed my skin felt firmer too so that was an added bonus! I don’t super love how it smells but it’s ok!

I picked this up in the Vault, thanks BR! I quite like Dr Lewinns products and this one sounded lovely. I don't get much sleep and it definitely shows on my skin so this product is definitely suited for me.

It comes in a 30ml bottle with a silver top and bottom, I find the packaging quite appealing. It has dual action chambers so when you press the top down they both come out separately then mix together.

It has a nice floral scent and a thick consistency, you do not need a lot of this. One pump is more than enough...if you do more you will have the most awful sticky face! I recommend starting off with less as you can always apply more if needed.

I pump out a small amount then gently mix together then apply all over my face, it dries down in about 5 minutes and you are left with the most soft feeling skin ever!

I use this 3 times a week as stated and the next morning my face always looks so fresh and smooth! My makeup applies like a dream and my skin just looks healthy and firm. Although the bottle is only 30ml it lasts forever so I think it is great value for money.

I am enjoying using this and I would buy it again.  Keep an eye out for when it is on sale!

I purchased this from the beauty vault.

Initially, I thought I would never spend this much on a product that is a ‘mask’, BUT wow! This is probably the best mask I have ever put on my skin!

I use it once/twice a week. My skin gets an amazing glow and dewy appearance once applied and makes my skin so soft the next day. I make sure to use it the night before an even to make my skin perfect for my makeup.

I had been searching for a product that had a Korean skincare effect and have finally found it. I will definitely be repurchasing!

I really enjoyed using this sleep mask. I woke up after using with my skin feeling hydrated, plumped and refreshed. I honestly don't know if it improved the look of fine lines / wrinkles but my skin felt softer, smoother and consistently more hydrated.

One pump of the product was enough to cover my face, neck and collarbones and using it 2-3 times a week it will last ages. I didn't notice if this improved my sleep at all, but I did notice that the mask can feel sticky on your pillow if you sleep on your side or tummy.

Overall I really enjoyed using this product and would definitely buy again.

I am forever trying new skin care products and was excited to be picked for this trial as I have never tried anything from Dr LeWinns range before. The packaging is great- easy to use large pump, clear container so you can see how much product you have left and visually the two tone product is nice. The pump works well and distrubutes a decent amount of product per pump- I used 2 pumps per application to cover my face and neck. The serum is thick and easy to spread, the scent is nice, refreshing but not overpowering and it sinks well into your skin. I used this product almost every second night and found that it has made my skin look really plump and hydrated which I'm very impressed with. In terms of anti-aging benefits I'd just had a botox top up when I started using this so can't say whether its made an impact there but I'm definitely happy with how my skin is looking over all.

On paper this certainly looks made for me, promising to improve skin hydration, elasticity and fatigue!

The concept of mixing 2 separate formulations has been done enough times now for it not to be a unique concept, but I love that it's done effortlessly with this product. It's just a standard pump bottle, there's no faff or excessive mixing, or uneven distribution. Perfect pump every time.

It smells fresh. I wouldn't say it was overtly fragranced which I like.

It is so cooling on the skin, it feels refreshing, which after an evening shower is just lovely.

Its slightly sticky to the touch once on the skin, nothing major though and it doesn't transfer to your pillow or bedding.

This is a product where the immediate effects aren't anything to shout about. 8 hours of sleep later though, you'll wake up to incredibly soft, smooth skin that feels like you've just applied a serum!

After 3 weeks of 3 x a week use I can honestly say it is fantastic. It does what it says. Skin is more hydrated, less fatigued and firmer.

I was selected in a BR trial to review this product and I'm very very grateful as I have found something I will definitely continue to use!

This sleep mask is packaged beautifully and is very easy to use - simply massage all over your face and neck every 2nd night after completing your normal skincare routine. I have been using 2 pumps per application but could actually get away with 1 1/2 and still get enough coverage.

I'd never heard of a sleep mask prior to this trial and all I can say is that this product is perfect for those who have tired skin and are time-poor. I love the idea of applying a mask and not having to wait 20 minutes or so before taking it off again.

I have found my skin to look and feel brighter, plumper, and less tired after using this for just over 2 weeks. I would've given it a perfect 5, however, this product didn't help my eye bags.

As I'm on the more mature side (45) my skin needs all the help and can get and I would absolutely purchase this product again for all the benefits I have noticed.

The only slight downside is that the mask leaves my skin very shiny and heavy feeling. but as you apply it before bed I really see no issue with that.

Love, love, love this sleep mask <3

I was lucky enough to win a place on the trial team for this product. It comes in a small bottle with the product split into 2 halves, when you use the pump you combine the 2 parts with your fingers before applying to your face. There is a slight fragrance which is meant to help you sleep better. I am unsure if this works or not as for me my sleep did not change when using this product. The formula also left my skin feeling a little sticky when it was on, to wash it off in the morning you do need to use a cleanser as water alone doesn't seen to move it. However it left my skin feeling amazing. My once dry skin now feels soft with no dry patches. It says to use this once or twice a week, I would suggest sticking to this as any more and your skin may be too moisturized and start to break out. All in all this is a great product and the only reason I have not rated it higher was due to the stickiness.
