Hi, I have some further doubts about niacinamide and acids.

What if they’re combined in a single product? Does niacinamide reduce to niacin and become useless? I’m using something like this: Aqua(Water), Mandelic Acid(10%[?]), Lactobionic Acid, Niacinamide, Sodium Hyaluronate, Allantoin, Hydroxyethylcellulose, Polysorbate 20, Ethylhexylglycerin, Phenoxyethanol, Parfum(Fragrance), Butylphenyl Methylpropional, Hydroxycitronellal, Limonene, Linalool. I’m not flushing [maybe shizo].

Niacin isn’t useless, it just causes flushing for some people – that’s all.

The amount of niacinamide hydrolysis depends on the pH of the product, how long it’s been stored for, and at what temperature. It’s also possible that there isn’t much niacinamide in the product. Unless it states the amount on the package there’s no way to know, it could be 0.1% or 4%.

If you’re not experiencing flushing and enjoy using the product – then keep using it!

Hope that helps 🙂

Locobase Repair performs just as well as petrolatum in study

In a double-blind study, a commercially available physiological lipid mixture (containing ceramide 3) was found to promote barrier recovery in SLS-irritated and tape-stripped human skin, compared with the untreated control area. However, the barrier recovery was not superior to its placebo (petrolatum) (Figure 15.2).

Ingredients of Locobase Repair: Petrolatum, Aqua, Paraffin, Paraffinum Liquidum, Glycerin, Sorbitan Oleate, Carnauba, Cholesterol, Ceramide 3, Oleic Acid, Palmitic Acid, Carbomer, Tromethamine

Review with Pictures (in German)

I’d like to see a comparison between the Locobase product that more directly compares the lipid mixture vs. petrolatum. Perhaps a setup with the Locobase vs. an emulsion with the same water to petrolatum proportions would work.
