With a focus on innovation and skin science (and packaging that looks like it could be in an art gallery), the luxury Swiss brand continues its legacy of high performance products with La Prairie White Caviar Illuminating Pearl Infusion and White Caviar Crème Extraordinaire. Here are four things to know.

1. They’re designed with light in mind

Anyone who’s tried to achieve the perfect glow to their skin knows it’s harder than it seems. The secret to getting it right: understanding light. “[People] want to see that glow, that light in the face which transports the image of beautiful, attractive, healthy skin,” says Dr. Daniel Stangl, director of innovation at La Prairie. “But we want to go beyond that and create luminosity.” Glowing or luminous skin, is really about how light interacts with your skin, through both absorption and reflection. But as you age, this process becomes more difficult: more pigmentation causes your skin to absorb (or destroy) light, while wrinkles and uneven skin make it more difficult for light to reflect off of it, meaning duller looking skin. Enter La Prairie’s White Caviar Illuminating Pearl Infusion and White Caviar Crème Extraordinaire.

2. They work together to target pigmentation

There are four common types of pigmentation we see on our skin, Dr. Stangl explains, reducing its natural glow. Grey pigments appear on the surface of the skin as a result of damage from pollution. Brown age spots can come from sun damage, but can also appear because of cells purging. Of course, there’s the familiar red hue caused by inflammation and irritants. There are also the yellow pigments that are the result of oxidative stress from damaging free radicals, leading to protein degradation—a.k.a. a loss of collagen.

Used together, the two new products target each type of pigmentation, aiming for a smoother complexion that looks rejuvenated. Skin then appears as if it’s glowing from within. (Pro-tip: Be sure to use them with SPF for further protection.)

3. Caviar is a key ingredient

Both La Prairie products are enriched with golden caviar extract. The luxe ingredient helps boost collagen production, smoothing and firming skin. A smoother surface means light is better able to reflect off the skin, creating that luminous glow.

4. There’s also a kind-of-secret ingredient

And by secret, we mean super exclusive. The brand’s White Caviar Crème Extraordinaire has illuminating Lumidose—a patented molecule developed and used only by La Prairie. Dr. Stangl says it took over 50 years of research to land on this molecule. What makes it so important? Lumidose is said to inhibit tyrosinase, an enzyme that produces melanin. Now, it doesn’t totally stop the creation of melanin, Dr. Stangl explains, but it does make it more difficult for brown spots to form, reducing the amount of light the skin absorbs.
