Photosensitivity: Lemon juice can make your skin more sensitive to UV rays. Using the treatment and then exposing skin to sun without protection can worsen pigmentation or cause burns. Remedy Daily+1
Skin irritation: The acidity of lemon could cause stinging, redness, burning—especially on sensitive skin or broken skin. If you feel burning, wash off immediately.
Avoid if you have active irritation, open wounds, sunburned skin, or known sensitivity to citrus.
Patch test first! Always do a small area first to check for allergic or irritant reaction.
Sun protection is mandatory, not optional. Without it, you may see minimal benefit and possibly worsening.
If spots change size, shape, color or become raised/itchy/bleeding, seek professional evaluation: these could be signs of skin cancer. Home remedies are not appropriate in such cases. RosyCheeked+1
Additional Tips to Boost Effectiveness
Exfoliate gently: On the days you’re not using this treatment, gentle exfoliation (like mild AHA or enzyme peel) may help speed removal of pigmented skin layers — but be careful not to over-exfoliate and irritate.
Use antioxidant skincare: Vitamin C serums, niacinamide, licorice extract and other tyrosinase inhibitors help fade spots and support healthy tone. (E.g., licorice extract glabridin inhibits melanin production) Healthline+1
Sun protection daily: Sunscreen (SPF 30+) daily even when indoors; reapply if you’ll be in sun. Wear hats/visor.
Healthy lifestyle: Adequate sleep, hydration, diet rich in antioxidants help skin repair and tone.
Be consistent: Texture and tone changes happen slowly; regular treatments 2-3 times/week, for weeks, matter more than occasional use.
Use proper skincare after: After applying the hack and rinsing, use a gentle moisturizer to keep skin barrier healthy. A strong barrier supports pigment fading.
Avoid picking or scratching spots: This can cause inflammation, which may lead to more pigmentation.
