Is there a hypoallergenic treatment that even people with sensitive skin can safely receive?

Hello! I have typical sensitive skin, which quickly becomes red and irritated with even the slightest change in cosmetics.

My skin condition has been really bad lately, so I want to get it treated, but I'm worried that if I get the wrong treatment for my sensitive skin, it might get worse.

Has anyone with sensitive skin like mine experienced any results that relieve dryness or soothe it without irritation? If you know of any way to achieve smooth, trouble-free skin after treatment, please share.
