Titanium is generally considered to be a hypoallergenic metal, which means that it is unlikely to cause irritation or allergic reactions in most people. However, it is still possible for some individuals to experience skin irritation or other allergic reactions to titanium, especially if they have sensitive skin or allergies to other metals.

If you are considering wearing titanium jewelry or other products and have concerns about potential skin irritation, it is recommended to do a patch test first. Apply a small amount of the product to a small area of the skin, such as the inside of your wrist or elbow, and wait for 24 hours to see if any redness, itching, or irritation occurs.

If you experience any discomfort or allergic reactions, it is best to avoid using titanium products and to seek advice from a dermatologist or medical professional. In general, titanium is considered to be a safe and low-risk material for use in jewelry, medical devices, and other applications, but it is always important to take proper precautions and to consult with a professional if you have any concerns.
