Remedy 6: Gentle Physical Exfoliation (Only If Skin Is Not Sensitive)
A soft brush or pumice stone once a week can remove dead skin cells. But if your skin is already irritated or sensitive, this will worsen hyperpigmentation. When in doubt, always opt for chemical exfoliation (lactic acid) over physical exfoliation.
Remedy 7: Anti-inflammatory Diet (If It Is Acanthosis Nigricans)
If your dark patches are acanthosis nigricans (thickened, velvety skin, not just darker), diet and hormone metabolism directly affect your skin . Reduce refined sugars and processed carbohydrates. Eat vegetables, lean protein, and healthy fats. By improving insulin sensitivity, acanthosis nigricans will gradually improve.
What DOESN’T Work and Can Damage Your Skin
Baking soda + concentrated lemon juice: Baking soda is very abrasive. Undiluted lemon juice is photosensitizing. Together they can burn and permanently damage the skin.
Coarse salt as an exfoliant: Too harsh for creases. It damages the skin barrier and worsens hyperpigmentation due to accumulated irritation.
Clay + concentrated lemon juice: Clay is abrasive. If you add undiluted lemon juice and go out in the sun, the photochemical burn can leave marks worse than the original ones.
