Is it wrong to use hyaluronic acid stock solution to make mud or is there something wrong with the hyaluronic acid stock solution I bought?

For the same hyaluronic acid essence product, some people feel good after using it, but some people feel it is like mud. Why is that? When rubbing mud occurs, most people will choose to stop using hyaluronic acid stock solution. Let’s understand it first before drawing any conclusions!

Reasons for rubbing hyaluronic acid stock solution into mud

Old skin with thick stratum corneum

In dry weather, your skin produces more flakes, or old cellulite, than usual. If you do not clean it regularly, when you apply the hyaluronic acid solution, the dandruff mixed with the hyaluronic acid solution may cause rubbing into the skin.

Water and oil in skin care products are not soluble

The primer used is oil-soluble, while the face cream used is water-soluble; or after applying the hydrophilic hyaluronic acid stock solution, you use lipophilic skin care products. Both of these situations will cause mud to form because water and oil are insoluble.

Reactions between skin care products

After applying the hyaluronic acid stock solution, if you immediately apply foundation or sunscreen containing metal ion ingredients such as titanium dioxide and zinc oxide, a reaction will occur and salts will be produced, which is the "mud" we see.
