Please help! Uncertain about serum formulation (for acneic skin)

Hi everyone! I am trying to formulate a water-based serum for my acneic/oily/dehydrated skin. 

This serum is meant to encourage certain chains on skin bacteria to ferment naturally-occurring glycerol in the skin into SCFA, which in vitro has shown to kill P. acnes. 

I included some plant ferments, lysates, prebiotics, and other by-products of fermentation that might encourage a healthier microbiome. 

Deionised water (28.35%)

MC-Glucan (9%)

Dimethyl Isosorbide (9%)

Lactococcus Ferment Lysate (9%)

Ophiopogon Japonicus root extract (7%)

Inulin (6%)

[Fructooligosaccharides, Beet root extract, Water] (4%)

Amber Extract (4%)

Leucidal Liquid (4%)

ProBioBalance [water, milk proteins, bifida ferment lysate] (4%)

ECOSKIN [alpha-glucan oligosaccharides, P.S. root juice, maltodextrin, lactobacillus] (4%)

Gluconolactone (3%)

Hydrolyzed Yeast Protein (3%)

Bio Chelate [water, saccharomyces zinc, saccharomyces copper, saccharomyces magnesium, saccharomyces Magnesium, saccharomyces Iron, saccharomyces Silicon] (2%)

Hydrolyzed hemp protein (2%)

Sucrose (1%)

Sodium Phytate (0.5%)

Silverion [silver citrate, citric acid] (0.15%) 

Please help! Am I missing anything? Preservatives OK? Chelators (sodium phytate OK)?

Thank you for all your help!
