• Sunspots (also known as age spots or liver spots):

These are flat, brown or black spots that appear on sun-exposed areas like the face, hands, and arms. 

• Freckles:

These are small, flat, brown spots that appear on the skin, often on the face and arms. 

• Rosacea:

• Rosacea is a chronic skin condition that causes redness, visible blood vessels, and sometimes small, red, pus-filled bumps on the face.
• It primarily affects the face, but can also affect the eyes and other parts of the body.
• While not a form of hyperpigmentation, rosacea can cause redness and discoloration, which can worsen with sun exposure.
