Common Name(s): Mgcl2,magnesium oil (concentrated solution),nigari
CAS Number: 7786-30-3
DESCRIPTION
What It Does: Provides topical magnesium delivery for muscle relaxation and anti-inflammatory skin conditioning.
Why It's Used: Wellness magnesium ingredient โ magnesium chloride's claimed transdermal delivery addresses widespread magnesium deficiency in a topical application that is growing in sports recovery and wellness skincare.
How It Works: Mgclโ provides mgยฒโบ ions for muscle relaxation (calcium channel antagonism). mgยฒโบ is cofactor for 300+ enzymes including serine palmitoyltransferase (ceramide synthesis). anti-inflammatory via mgยฒโบ stabilisation of mast cells reducing histamine release. keratinocyte barrier protein synthesis support.
Typically Found In: Sports recovery products,muscle relaxation,bath products,wellness skincare

SCIENTIFIC NOTE
The transdermal magnesium absorption debate (highly contested) centres on whether mgยฒโบ ions can meaningfully cross intact stratum corneum in amounts sufficient to elevate systemic or even local tissue magnesium levels. while rct evidence is limited, magnesium's well-established anti-inflammatory skin surface effects (mast cell stabilisation, keratinocyte proliferation inhibition) provide cosmetic-level rationale for topical application independent of systemic absorption claims.
