Hi, redness on the skin can be due to a variety of causes, including:
- Rashes such as acne, eczema, allergies, psoriasis, rosacea
- Skin growths such as angiomas, vascular birthmarks
- Post-inflammatory erythema due to previous inflammation from acne or eczema
Given that there are broad-ranging possibilities, it is best to seek medical attention from either your local doctor or dermatologist to assess your skin condition further so that appropriate management strategies can be advised. Hope this helps.
