Common Name(s): Msm,organic sulfur,anti-inflammatory sulfur
CAS Number: 67-71-0
DESCRIPTION
What It Does: Provides anti-inflammatory organic sulfur for skin strengthening from msm.
Why It's Used: Bioavailable organic sulfur anti-inflammatory — msm provides the sulfur required for keratin disulfide bonding and collagen sulfur amino acids alongside anti-inflammatory activity, making it a functional sulfur supplement for both structural skin proteins and inflammatory skin conditions.
How It Works: (ch3)2so2: highly bioavailable sulfur. anti-inflammatory: nf-kb inhibition + oxidative stress reduction. keratin: disulfide bond sulfur source. collagen: methionine + cysteine content. anti-acne: anti-inflammatory + antimicrobial. oral supplement: joint pain, anti-inflammatory. topical: skin brightening + anti-inflammatory.
Typically Found In: Anti-inflammatory skin care,strengthening products

SCIENTIFIC NOTE
Msm sulfur bioavailability: msm's dimethyl sulfone form provides sulfur without the digestive hydrogen sulfide issues of inorganic sulfates. topically, msm penetrates sc readily from low mw (94 da) + high oil-water partition compatibility, delivering sulfur to dermis for keratin/collagen synthesis cofactor function. this combination of sc penetration + sulfur bioavailability makes msm the most practical topical sulfur supplement.
