Why Lemon Juice Can Burn Skin Instead of Brightening

Lemon juice is often touted as a natural remedy for brightening dull skin or fading dark spots. Its high vitamin C content and natural acidity seem like the perfect solution for a glowing complexion. But applying lemon juice directly to your face can do more harm than good.

The problem lies in its acidity. Lemon juice has a low pH, which can disrupt your skin’s natural barrier. When applied directly, it can cause stinging, redness, peeling, and even chemical burns—especially on sensitive or damaged skin. Sun exposure after using lemon juice can trigger phytophotodermatitis, a reaction that makes the skin more prone to dark spots and irritation instead of brightening it.

Even small amounts can irritate acne-prone skin, worsening inflammation and dryness. Many people mistakenly think “natural = safe,” but citrus acids are potent and should be used carefully and in diluted forms in skincare products specifically formulated for topical use.

The Safer Alternative: Instead of raw lemon juice, opt for vitamin C serums or creams with a balanced pH. These provide the brightening and antioxidant benefits without the risks of burns or sensitivity.

Natural remedies can be tempting, but some “quick fixes” like lemon juice are better left out of your skincare routine for the sake of your skin’s health.
