So which one reigns supreme? In my opinion, The Eye Concentrate is superior. I think even some of the more experienced La Mer rep would agree with me (and they have).
A mini breakdown of each from their website-
The Balm Intense-
The new Marine De-Puff Ferment™, The Lifting Ferment™ and a potent concentration of The Miracle Broth™ - the seaborne elixir known for its healing energies - penetrate deep within the skin's surface for a remarkable change, while the unique balm texture offers the utmost in comfort.
In a short while, the look of puffiness, lines and wrinkles is diminished as clarity is revealed. La Mer's proprietary silver-tipped applicator cools skin on contact to help stimulate mircocirculation
This concentrated cream utilizes three unique forms of Miracle Broth™ to deeply condition, smooth and hydrate the delicate eye area. It significantly reduces the appearance of dark circles, lines and wrinkles for a luminous new life.
Fortified with an iron-rich mineral, The Eye Concentrate dramatically dissolves the appearance of dark circles. It works in tandem with a specially-engineered, silver-tipped applicator which helps cool the skin, immediately improving micro-circulation.
The Price- Both $165
Hydration- The Balm Intense takes this one
Dark Circles- The Concentrate, the Balm Intense doesn't even treat dark circles.
Lines and Wrinkles- Both are equally good in this department. It's La Mer afterall.
Puffiness- Balm Intense.
So why do i think The Eye Concentrate is better? Simply because the anti-aging results are more noticeable than when I was on the Balm Intense and I think it absorbs better than the Balm. Sometimes the Balm just sits on top of your skin, and I don't think you should use creams that are too heavy around your eyes.
They are equally great products, so it's really up to what you're looking for. I think the price is decent for La Mer. They could've charge up to $200 and I think people would still buy it. I think they were $185 at some point? Anyways, the price currently is $165.
La Mer always put out great products and some people don't like the brand, but from my personal experience, they've always delivered.
