Healing in a bottle!

As Kauai's first para medical esthetician, and at 72, I no longer want super aggressive treatments ,or products. I found out about Leahlani through a beautiful young woman on Kauai 's lovely North Shore. One sniff and I was hooked! I have severe and disfiguring scars from an accident many years before, and find that the potions and lotions from Leah make me feel so much better, and I feel an internal healing every time I use them. Leahlani, I have come home!

It really is like bottled sunshine!

Not only does it brighten and moisturize, it also has the most wonderful aroma therapy benefits. I use it every morning and feel energized and ready to go! I work 12 hour shifts and it leaves my skin feeling healthy and hydrated throughout.

I loved Siren. My skin has never felt or looked better. The scars and discolorations I have from constant sunshine, slowly faded away. My skin tone evened out and I AM HAPPY! You won't regret this or any of Leahlani's products.

I honestly love every product from Leahlani! This is the first company that I continue to order from, because the products are all high quality and actually produce awesome results. My skin is brighter, smoother, and more moisturized. People constantly compliment my skin and tell me I’m glowing. Also they provide a powerful aromatherapy experience that is part of my healing + self-care journey. Couldn’t say enough great things about the Siren Serum, Mermaid Mask, cleanser, Honey Love, Meli Glow, Bless Balm, and oh my gosh, all the many products I’ve purchased!

Sunlight in a bottle

I AM BEYOND OBSESSED, with all these serum . I started with the PM one, since battleling with cancer my skin has drastically changed and on serious need of tlc. And I wanted to try something that seems natural and full of light. And these do not disappoint. Also when combining with Honey Love my skin is ultra soft and smooth. And the smell is paradise. Definitely a repeat customer. Thank you for making quality products that not only work but also changes your mood positively.

Even Glowing Skin

Siren Serum is perfection. It evens out my sensitive, red skin and gives even, glowing results. It works great under makeup, works morning or night and smells heavenly. A new staple item. Add a touch of Mahina on top for nighttime.


The best my skin has ever looked after one week!

I'm a longtime and lifelong Leahlani user. A daily serum was the last thing for me to try. I previously used a simple Rosehip Oil. Mahina is a wonderful nighttime rich boost of moisture but Siren has completely evened out my pale, sensitive, red skin tone and texture in only 1 week! My skin is bright, glowy and doesnt need makeup. I don't even recognize myself - it's that good. I use Pamplemousse, Honey Love, and Meli Glow as well. I had congested acne prone, scarred skin and I couldn't be more pleased with the results. The smell is beyond words as well! A must have for daily use!
