Application and Timing
- The Test: Before applying, do a patch test on a small, inconspicuous area of your skin (like behind your ear) to ensure you don’t have a severe reaction.
- Targeting: Apply the diluted paste only to the specific blemish or dark mark you wish to treat. Avoid using it near the eyes or on broken skin.
- The “Overnight” Limit: While the claim is “overnight,” garlic is incredibly potent. For your first attempt, leave the mixture on for only 10 to 15 minutes, then rinse thoroughly. If your skin tolerates this well, you may gradually increase the application time, but generally, it should not be left on for the full night due to its irritating potential.
⚠️ Critical Safety Warning: The Risk of Chemical Burns
While anecdotal evidence is strong, dermatologists caution against using raw garlic due to the high risk of irritation and, in severe cases, chemical burns.
- Dermatitis: Raw garlic can easily cause contact dermatitis, leading to significant redness, itching, and swelling.
- Worsening Hyperpigmentation: The inflammation caused by a garlic burn can paradoxically lead to worse and longer-lasting dark marks (PIH) than the original blemish.
Always use a carrier oil/gel, test a small area first, and if you feel any burning or intense stinging, wash it off immediately. For severe or persistent dark marks, professional treatments like chemical peels or retinoids are often safer and more effective.
In conclusion, while garlic contains active compounds that can fight blemishes, it’s a home remedy best used with extreme caution, moderation, and realistic expectations regarding that “overnight” promise.
