Renewable energies. 1000 tons of CO2 emissions avoided each year thanks to our geothermal program.


I've been using this throughout the summer as I have really oily skin but didn't want to forgo moisturiser completely. I normally don't like mattifying moisturisers as I like my skin to have a soft glow, but this one was perfect - it didn't give that solid matt feel/look and kept my skin nicely moisturised. It is great under make-up as there is no "balling" which often happens with mattifying moisturisers. It also didn't irritate my sensitive spot prone skin, so very effective.


Day by day the skin’s texture is continually refined, enlarged pores are tightened, andsebum managed. The complexion is left looking mattified and smooth with an intensely moisturised feel.

Hydrating for up to 8 hours. Mattifying for up to 6 hours.

Rated 4 out of 5 by from Feels so high end! I am recently a new fan of this brand, so I thought I would give this a go since my skin can get quite oily, this really is an amazing daytime moisturiser which protects from any shine. However I wouldn't recommend this for using under makeup even though it says that it is "an excellent makeup base", because I think it's too dry to the point where the foundation will look quite dull and grey, but this is amazing for during the day without makeup. The packaging itself is completely matte which makes it feel really high end.

Rated 5 out of 5 by from It's taken a long time but finally I've found the perfect moisturiser I have been struggling with moisturisers for a few years now, i think my skin changed in my late twenties. I have combination skin and every moisturiser i bought left me shiney within an hour, making my foundation slide off my face. I've spent a fortune on foundations, creams, primers and blotting powders. I would have to take blotting powder everywhere with me and continually re-apply to my t-zone. I know this says it is for oily skin, but i have been using it for 2 weeks morning and night and my skin feels soft and smooth and it hasn't dried out my cheeks. It definitely makes a difference with shine, I have ditched the blotting powders now and my make-up lasts a lot longer. I wouldn't say it stops shine completely but it has made a huge difference. I am so impressed i am now buying a lot of the other products in the range including the foundation and hoping that i am equally as impressed. It is a good base for your make-up and you only need a small amount.

Rated 5 out of 5 by from The perfect moisturiser for oily skin I never take the time to review my skincare products, but this one leaves my skin perfectly balanced between moisturised and oily. Totally non-greasy, sinks in straight away, deals with dryness but mattifies instantly. Really does what it says on the tin - my skin stays matte for longer (I'm very oily) and when used under make-up it's a little longer until shine starts to appear. It won't eliminate shininess / oil, but get your skin off to a great start. It's helping to shrink my acne too! You only need a tiny bit at a time but I wish there was a little more product in the bottle.

Rated 5 out of 5 by from No more need for a primer I have looked at this product several times but have always been put off by the price. Usually I use a primer before applying my foundation as my skin is very oily and by the afternoon my cheeks are giving off a gloss appearance. Having tried this product it is definitely an oil absorbing moisturiser and no longer have to apply a primer. The only negative is that there it is a small bottle for the price but if you weigh up no longer requiring a primer then the price is reasonable. I will buy another and recommend if your foundation is slipping off your face in the T zone.

Rated 5 out of 5 by from My favourite new moisturizer! Ever since I've tried this moisturizer, I have never looked back! Using this has made such a dramatic difference to the size of my pores and keeping shine at bay. I love that this moisturizer feels incredibly light on the skin whilst keeping it very hydrated too for a very long time at the same time. The scent is very light and refreshing like their Effaclar duo which I also love, and did not feel harsh on my sensitive skin either. I also found that it is effective to use as a base before makeup as well due to the velvety feeling that gives to my skin, which is a bonus. I would highly recommend this product as a little does go a long way and it really does help with enlarged pores and excess shine. I love this moisturizer so much that I have repurchased it again!

Rated 5 out of 5 by from Loving this! Great under foundation! I've been using this product for the last coupel of weeks and I'm loving it. I've been using it before bed and under my foundation and the difference it's making is incredible - it makes my foundation smooth and last longer than anything else. The bottle is great sized, dispenses just the right amount. There's no unpleasant or overpowering fragrance to it, and it's not too sticky or anything. I'd recommend this for anyone who wants to use it under foundation to help mattify it. Love it. Nice, smooth finish with powder or liquid foundation. Can't fault it.

Rated 5 out of 5 by from GREAT moisturiser for 40 skin too if oily/acne I use all the effaclar products but never bought this as I thought it would be mainly a mattifier and not much of a moisturiser. I tend to use the Effaclar H moisturiser for dry skin, which is great in winter. But now in te hot summer I thought I'd try the mat+ moisturiser and my 43 year old acneic skin is super happy. It visibly reduces pores, and it moisturises by sinking in immidiatlely; I also think it helps with the acne . Won't take all shine away (but that is not why I bought it - some shine reduces look of wrinkles anyway!). Super happy!
