Why you have dark circles — the 4 causes
Pigmentation type: genuine extra melanin, often genetic, common in Indian and Mediterranean skin. Vascular type: blue/purple tint from blood vessels showing through thin skin. Structural type: shadows from under-eye hollows or eye-bags, an architecture problem oils can't fix. Lifestyle type: worsened by poor sleep, dehydration, screen strain, allergies. Oils help most with pigmentation and thin-skin vascular types.
Best oils for pigmentation-type dark circles
Sweet almond oil is the traditional Indian under-eye remedy — its vitamin E and gentle profile suit the delicate area, and consistent nightly use can lighten pigmentation over 8–12 weeks. Rosehip seed oil contains natural trans-retinoic acid that supports cell turnover and gradual brightening. Apply only a single drop, patted gently — never rubbed.
Best oils for thin-skin (vascular) dark circles
Squalane is lightweight, non-irritating, and helps the under-eye skin retain moisture, which slightly plumps thin skin and reduces how much the blood vessels show through. It's the safest option for sensitive eyes. Apricot kernel oil is similarly gentle and slightly richer for drier under-eye skin.
How to apply oil under the eyes safely
Use one drop maximum for both eyes. Warm it between fingertips. Pat — never rub or drag — along the orbital bone, staying about a centimetre away from the lash line so it doesn't migrate into the eye overnight. Apply at night after cleansing. Morning: a drop of squalane under makeup works as a smoothing base.
What oils can't fix
Structural dark circles — hollows, eye-bags, deep tear troughs — are an anatomy issue. No oil corrects them; only fillers or surgery do. Also, if dark circles appeared suddenly or are very pronounced, check for iron deficiency, thyroid issues, or allergies with a doctor. Manage sleep, hydration, and screen breaks alongside any oil routine.
