Dark circles and under-eye puffiness can have several causes, and the same appearance may come from very different factors. Genetics, pigmentation, visible vessels, allergies, facial anatomy, sleep and age-related changes can all contribute.
Common causes of dark circles
Genetics and facial structure
Some people naturally have more pigment around the eyes, thinner skin or deeper tear troughs that create shadowing. Skincare can improve surface quality but cannot fully change facial anatomy.
Allergies and rubbing
Allergies can cause swelling and itching, while repeated rubbing may increase irritation and discoloration.
Age-related changes
With age, changes in skin thickness, collagen and facial volume can make vessels and shadows more visible.
Sun exposure
UV exposure can worsen pigmentation, making consistent sun protection important.
Sleep
Poor sleep can make the under-eye area look more tired or shadowed, although it is rarely the only cause of persistent dark circles.
What causes puffiness?
Temporary puffiness can relate to fluid retention, allergies, sleep, diet or irritation. Persistent under-eye bags can also reflect normal anatomical and age-related changes.
What can skincare realistically do?
Hydrating products can improve dryness and fine surface lines. Brightening ingredients may help when pigment contributes. Eye products with peptides, antioxidants or other targeted ingredients can support the visible quality of the area, but no topical product treats every cause.

Sun protection matters
Use broad-spectrum sunscreen every morning and consider sunglasses during outdoor exposure. See Gel Sunscreen Broad-Spectrum SPF 50 or compare Sunscreens.
When to seek medical advice
Sudden, one-sided or persistent swelling, significant irritation, or changes accompanied by other symptoms should be assessed by a healthcare professional. For long-standing anatomical hollowness or bags, a clinician can explain options that skincare cannot provide.
