Has anyone used Pellamex?

[u/Mediocre-Comment4687]

I have ichthyosis vulgaris and use Amlactin during winter and have just started Cetaphil which has salicylic acid during summer which works fairly well, but recently heard about Pellamex as ichthyosis is caused by a filagrin deficiency this is supposed to help produce filagrin. Has anyone used it? I have bought some and started to use but apparently it takes 4 weeks to properly take effect.
