With 4D Zinc Salt, it rapidly reacts with malodorous substances such as hydrogen sulfide and mercaptans, converting them into new low-odor or odorless compounds to remove odor and suppress odor diffusion. It avoids the drawback of conventional aluminum salts that block pores for antiperspirant effect, which may lead to skin darkening<\/p>\n\n\n\n

Mechanism of Action<\/h3>\n\n\n\n

1. Odor chemical neutralization pathway: Zinc ions bind with malodorous molecules such as hydrogen sulfide and ammonia, converting them into low-odor or odorless substances to suppress odor diffusion, rather than masking odor with fragrance.
2. Selective microbiome balancing pathway: Alter cell membrane permeability of harmful microbes and inactivate bacterial DNA synthase; inhibit bacterial sulfatase to reduce generation of odor precursors; selectively regulate odor-producing microbes including *Cutibacterium acnes*, *Malassezia* and *Staphylococcus aureus* to maintain balanced skin microbiota.
3. Sebum regulation pathway: Inhibit 5\u03b1-reductase activity, reduce triglyceride synthesis in sebum and improve excessive sebum secretion.
4. Soothing & repairing pathway: Downregulate expression of inflammatory factors TLR\u20112, TNF\u2011\u03b1 and IL\u20118; promote proliferation and migration of keratinocytes to relieve skin inflammatory stress damage.<\/p>\n\n\n\n

Experimental Data<\/h3>\n\n\n\n

1. 5\u03b1-reductase inhibition test: At 2% loading, 5\u03b1-reductase inhibition rate reaches 75.75%.
2. Lipid inhibition test: 2% sample achieves 32.1% inhibition on lipid production.
3. In-vitro bacteriostatic test: At 2% loading, inhibition rate against *Malassezia* is 70%, *Cutibacterium acnes* 65%; *Staphylococcus aureus* 79.2%, *Staphylococcus epidermidis* 76.7%.
4. Odor molecule neutralization test: 1% 4D Zinc Salt antiperspirant completely removes hydrogen sulfide within 12 min and efficiently reduces ammonia concentration.
5. Human anti-acne in-vivo test: Formulation with 2% active loading shows 63.77% reduction in acne lesion volume at day 7; 75.37% reduction at day 14, with notable improvement in GAGS acne grading score.
6. Human scalp anti-dandruff test: At 2% loading, scalp dandruff is reduced by nearly 73% after 3 days; scalp flake improvement rate reaches 74.2% after 8 days.<\/p>\n","protected":false},"excerpt":{"rendered":"
