What’s inside
Ingredients you know, doing what they say.
Six hard-working ingredient families. We name every active by the form it takes and promise only what is printed on the jar.
01 · Hydrates
Hyaluronic Acid
Holds water at the skin surface for a smooth, plump look. Fine lines look less visible on well-hydrated skin.
02 · Softens
Collagen
Hydrolyzed collagen forms a light, moisture-holding film that leaves skin feeling soft and supple.
03 · Smooths
Retinol
A form of vitamin A that softens the look of fine lines and uneven texture with consistent use.
04 · Brightens
Vitamin C
A stable form (sodium ascorbyl phosphate) that helps dull-looking skin look brighter and more even.
05 · Firms
Peptides
Short chains of amino acids that help skin look smoother and firmer — around the eyes and beyond.
06 · Comforts
Botanicals
Aloe, green tea, chamomile, jojoba and olive oils for daily comfort and lasting moisture.

Love this stuff!!
I’m not one to leave reviews although this stuff really impressed me. I’m pretty oily as it is normally, and it’s hard for me to find a moisturizer or a night cream that won’t double up the oil, affordable, and clog my…

FAQ
Good questions
Where can I buy Nature Theory?+
All our creams are sold on Amazon. Every “Get on Amazon” button opens the product page, so you get Prime shipping and Amazon’s easy returns.
Which cream should I start with?+
Take the 30-second skin quiz. If you want one jar for day and night, start with the Collagen Day & Night Cream.
Can I use more than one cream?+
Yes. A simple routine is Radiance or Hydro Care in the morning, Retinol at night, and the Eye Cream twice a day. Neck cream goes below the jawline.
Do I need sunscreen?+
Yes. Several of our creams contain vitamin A (retinol or retinyl palmitate), which can make skin more sensitive to the sun. Wear sunscreen every day.
Are the creams fragrance-free?+
They have no added fragrance and no parabens. Always patch test on the inner arm before first use.
Can I use them while pregnant or nursing?+
Ask your physician first, especially for products with retinol.
