Science
Mechanism of Action
Strontium is believed to exert its effects by exchanging with calcium within cellular compartments, contributing to soothing and anti-inflammatory responses that mitigate redness and discomfort. It is also thought to reinforce the skin's natural protective barrier, thereby improving moisture retention and offering defense against environmental stressors. Additionally, strontium may play a role in supporting collagen synthesis, which is crucial for maintaining skin firmness and elasticity. However, it's noted that at high concentrations, stable strontium may stimulate histamine release from mast cells.

Key findings
- 01 A topical strontium cream significantly reduced pruritus (itching) in participants with Hidradenitis Suppurativa after one week. Mean itch scores decreased from 3.80±0.90 to 2.28±1.50 (p<0.001). However, 60% of participants reported stinging upon application. The specific form of strontium (e.g., citrate) and its concentration were not specified in the abstract.

Safety Profile
The Scientific Committee on Cosmetic and Non-Food Products (SCCNFP) stated that the 'strontium cation is not toxic by itself,' but stressed that individual compounds should be evaluated on a case-by-case basis; Strontium Citrate has not been specifically reviewed by the CIR or SCCNFP. A significant concern for topical application is the reported stinging in 60% of participants using a strontium cream. Additionally, absorption through compromised or abraded skin can be significant (up to 57%). While oral strontium citrate is available as a supplement, it has been associated with gastrointestinal issues and skin reactions such as eczema, and a severe case of DRESS syndrome was reported with high oral intake (1.36 g daily).

Verdict
Despite strontium's theoretical benefits for soothing and barrier support, the high incidence of stinging reported in a relevant topical application, combined with the lack of specific clinical data for Strontium Citrate's topical efficacy and optimal concentration, renders its suitability for precision skincare questionable without further research.
