100% of women saw Visibly Firmer, Softer Skin (and Eyes) After 4 Weeks*

KEY BENEFITS
HOW TO USE
INGREDIENTS

Resist & Lift

Stimulates Hyaluronic Acid (HA) production (HA = Fountain of Youth key skin molecule). Ever wonder how to enhance collagen production in skin? Our spectrum of HA's quickly work to help make skin (and eyes) behave and look younger through healthier skin that builds itself back up. An all in one anti-aging firming, lifting, hydrating serum for the face, around the eyes, neck, chest, hand areas.
Simply Apply & Dry

Apply one to two dropperfuls morning and night after cleansing. We are serious when we say to apply the skin firming serum twice a day; otherwise, those unique regenerative skin-building hyaluronic acid benefits may never happen.

More Information

Apply before other serums, retinols or a moisturizer, or facial oil. After using Caire's serum for smooth skin you may elect not to use a moisturizer depending on your skin type.

Use the multi molecular hyaluronic serum s on the face, neck, chest, and/or back of hands and wherever else you feel the need.

Eye-vantage:Pat gently around eyes but don’t miss the under eye, eyelid, and all around. Feeding this ocular area is a win. Because with consistent use, you can help lift up sags and bags around the eye area - one of the top skin concerns from hormone-caused aging.

1 oz/30 ml Serum - 1 month supply, used twice daily (based on 1 dropper per use).

KANOE GLOWS FROM THE INSIDE OUT WITH CAIRE

"I love the Caire Serum & Mask, I use the serum twice a day and the mask twice a week. I noticed immediately that my skin has a glow. It feels soft and nourished. And while I love the immediate benefits, I also know that it's regenerating for my skin long term. As I'm aging, I realize that there's more than I need to do to make sure that my skin is healthy and moisturize. And I know the care beauty is doing that work in the short term and in the long term."
