skin serum

Are any of these "actives" at a percentage high enough to serve any real purpose?  This is a facial serum, the rest is water, some plant extracts and some oils (not my formula)  Should any of these levels be increased/decreased/removed to make it more efficacious?

0.71% Niacinamide
0.71% Hyaluronic Acid Molecular weight 800-1200kDa
0.10% Beta Glucan Powder Extract (what purpose does this serve?)
1.78% Sodium Ascorbyl Phosphate
4.02% Capric/caprylic triglycerides/Teprenone (not familiar with teprenone)

    I think if you searched on ulprospector you should be able to find the normal usage rates. 
    • Niacinamide - 2% or higher should be fine. Some brands have them up to 10%
    • Hyaluronic Acid - 1% or less should be fine. 
    • Beta Glucan Powder Extract - 0.1% raw powder or lower should be fine. Said to boost collagen / healing, smoothen rough skin. 
    • Sodium Ascorbyl Phosphate - 1% or higher should be fine. Some brands have them up to 12%. 
    • Caprylic/Capric Triglyceride (and) Teprenone - See Renovage by Croda, 3%.
