Hi, can one use liquid or silicone lubricant on Shabbos?
It isn’t clear from your question which halachos you are referring to. My assumption is that you are asking in regard to memareiach- smearing. If it is runny and not thick it would be permitted. See the following post which talk about similar topics https://dinonline.org/2016/03/01/antibacterial-gel-on-shabbos/ https://dinonline.org/2019/12/26/lotion-on-shabbos/
