The science of Sana Raíz
Every ingredient, chosen with intention. Here is what each one is, what it does, and the research behind it.
Peptides and nourishing butters, explained in plain words.
We believe you deserve to understand what you put on your skin. Each ingredient below links to a full article with the studies, so you can read them yourself.
GHK-Cu
The copper peptide
A tiny peptide your own body makes, bound to copper. Its natural levels decline with age.
Helps skin look firmer, smoother and more radiant.
First identified in human plasma in 1973, it lends formulas a natural blue tint.
PDRN
The renewal messenger
Purified DNA fragments, traditionally from salmon trout. The Korean clinic favorite now known as "salmon DNA."
Supports skin's natural renewal for a hydrated, resilient look.
It moved from Korean clinics into serums and creams in 2025 and 2026.
Hyaluronic Acid
The moisture keeper
A natural sugar molecule that holds on to water. Your skin already makes it.
Gives skin a plump, smooth, hydrated look.
About half of all the hyaluronic acid in your body lives in your skin.
Ectoin
The protector
A protective molecule made by microorganisms that thrive in salt lakes and deserts.
Helps skin hold on to moisture and feel calm and comfortable.
Hyaluronic acid draws water in; ectoin helps your skin keep it.
Mango Butter
The nourishing butter
A rich natural butter pressed from the kernel inside the mango seed.
Softens and comforts dry hands, without a greasy feel.
Solid in the jar, it melts the moment it touches your skin.
Where each ingredient lives
What our community asks
Does "salmon DNA" mean there is fish in my serum?
PDRN is made of purified DNA fragments; proteins are removed during purification. If you have a fish allergy, please check with your doctor before use.
Is bigger hyaluronic acid always better?
Not necessarily. Smaller molecules reach the outer layer of the skin, while larger ones remain on the surface and form a moisture film.
Are peptides just a trend?
GHK-Cu has been studied for about 50 years. It is a classic that has finally reached everyday skincare.
