Spf of dreams

I love this SPF and I have used many to try and find one to suit my acne prone skin, always going back to this one as my favourite . This SPF is on the pricey side which is my only complaint as there are many that are able to do the same thing at a fraction of the cost. However, this one does not make my skin breakout and leaves a nice glow to my skin . Can’t fault it only the price !

To oily

I have used the older version of this protecting fluid for many years. I liked that very much, but this new version is to oily for my skin. After one or two hours my skin gets a ugly shine. Maybe for dryer skin this works very good, but not for oily or combination skin.

Not so sure

I find this fluid irritates my skin and also leaves an oily film . It does leave a whit residue which is unavoidable due to the mineral component . The consistency is good but there is something in it which does not sut my sensitive skin. Could it be the colourig?

This SPF is so light, kind of like a runny lotion. Yet is so powerfully strong. It has a lovely subtle smell that is not irritating. It sinks into the skin quickly. It leaves no white cast. It simply leaves the skin hydrated and protected. This was my facial sunscreen when we visited Egypt - it did it's job, thank you. Wil absolutely repurchase and use again.

Best Use: Hydration, Hyperpigmentation, Anti-Aging

The best

I have waited for so long to be able to buy this SPF cream from SpaceNK. I’m so glad they finally have this in store. For me this is the best sunscreen on the market even though the price is a little steep. But a little goes a long way and the protection offered is one of the best. Your face will not get oily with this and you will not have a white cast upon application. I really love the packaging and the way it distributes the cream. So you get what you paid for with La Mer
