Reviews

Silky and smooth skin

"The Longevity serum feels silky and smooth, absorbed into thirsty skin like a delicious cocktail on a hot day. Followed by the Longevity cream, morning and evening, my face feels cool and nourished, ready for the day or for sleep."

— Dr H. (5/5)

Dewy Milk

"Lovely cream. Perfect balance for my skin"

— Amy M. (5/5)

So so good

"Used this cream for 1 week now and I just love how my skin looks. Plumpy and hydrated. So so good. A really well made product"

— Ann P. (5/5)

Exceeded expectations

"I cannot rave about this product enough! I was concerned it might be too light but given I'm staying in a humid and hot environment, I gave it a go. The texture is light but still creamy and it absorbs beautifully providing a nice hydration boost. What surprised me, was how well my makeup stayed put after a day out in humidity, heat and sweat. It's a lovely base for products and my skin looks firmer and hydrated."

— Catherine (5/5)

Never arrived

"Never arrived"

— Clare M. (5/5)

So light weight and hydrating

"I absolutely love how lightweight and hydrating this moisturiser is! It has a serum like texture but still provides deep hydration. I have dry skin and find it leaves my skin feeling hydrated for hours after application which I love!"

— Charlotte (5/5)

Lightweight, hydrating, smells amazing

"I love this moisturiser I use it every morning for a lightweight, hydrating finish. It sits perfectly under my makeup and has a really nice scent to it."

— Jade E. (5/5)

My Go To Summer Moisturiser

"I’ve been using the Dewy Milk Moisturizer every day and I genuinely love it. In the summer I hate the feeling of wearing lots of products on my skin, so on most days it’s just my skincare, and this has become a staple. It’s so lightweight but gives my skin the perfect amount of hydration, leaving it feeling fresh, comfortable and glowy without feeling greasy. The hydration genuinely lasts all day, which is exactly what I want when it’s warm outside. My skin stays soft, nourished and healthy looking from morning until evening. Definitely one I’ll be keeping in my routine!"

— Makeuppbykayleigh (5/5)

— Teee (5/5)

Gorgeous

"Absolutely gorgeous! Love the texture, the pump application and the scent! It’s so good, sooths my skin and gives a nice glow"

— iflyo (5/5)
