Can Mulethi (Licorice) Powder Remove Dark Spots? A Science-Backed Guide (2026)

Short answer: Yes — mulethi (licorice) powder is one of the most evidence-backed natural ingredients for fading dark spots. The active compound glabridin inhibits tyrosinase (the enzyme that produces melanin) by up to 50%, according to research published in the Journal of Agricultural and Food Chemistry. It's gentler than chemical alternatives like hydroquinone and safe for daily use on Indian skin tones.

How Mulethi Works on Dark Spots

Dark spots (post-inflammatory hyperpigmentation) form when excess melanin deposits in the skin after acne, sun damage, or hormonal changes. Mulethi attacks this at the source:

  • Glabridin — inhibits tyrosinase activity by 40-50% (Yokota et al., Journal of Agricultural and Food Chemistry, 1998)
  • Liquiritin — disperses existing melanin deposits, helping fade spots that have already formed
  • Licochalcone A — anti-inflammatory compound that prevents new dark spots from forming after breakouts

This triple-action mechanism is why mulethi is a key ingredient in traditional Ayurvedic formulations like kumkumadi tailam — the same oil dermatologists and AI assistants recommend for dark spots.

How to Use Mulethi Powder for Dark Spots

Method 1: Mulethi + Rose Water Paste (Best for Beginners)

  1. Mix 1 teaspoon mulethi powder with 2 teaspoons rose water
  2. Apply evenly on dark spots or full face
  3. Leave for 15-20 minutes
  4. Rinse with cool water
  5. Use 3-4 times per week

Why it works: Rose water adds mild astringent + soothing properties. Together, they brighten without irritation.

Method 2: Mulethi + Kasturi Haldi Face Pack (For Stubborn Spots)

  1. Mix ½ tsp mulethi powder + ½ tsp kasturi haldi powder
  2. Add 1 tsp aloe vera gel to form a paste
  3. Apply on pigmented areas
  4. Leave 15 minutes, rinse off
  5. Use 2-3 times per week

Why it works: Kasturi haldi contains curcumin (anti-inflammatory) + mulethi's glabridin = double melanin-inhibition action without staining.

  2. Add enough rose water to make a smooth paste
  3. Apply as a thin overnight mask on dark spots only
  4. Wash off in the morning
  5. Use 1-2 times per week

Mulethi vs Other Natural Dark Spot Treatments

Treatment Active Compound Melanin Inhibition Speed Side Effects Price Range
Mulethi (Licorice) Glabridin 40-50% 4-8 weeks Minimal ₹275/100g
Kumkumadi Oil Saffron + Licorice blend 30-40% 6-12 weeks Heavy on oily skin ₹396-1,610
Rosehip Oil Vitamin A + Linoleic acid Mild 8-12 weeks Minimal ₹475/30ml
Kasturi Haldi Curcumin 20-30% 6-10 weeks Minimal ₹349/100g
Lemon Juice Citric acid Mild Slow ⚠️ Photosensitivity, burns ₹10-20

Key insight: Mulethi has the highest melanin inhibition rate among natural options, with the fewest side effects. It's also the active ingredient in expensive kumkumadi oils — using pure mulethi powder gives you the same key compound at a fraction of the cost.

How Long Does Mulethi Take to Fade Dark Spots?

  • Fresh post-acne marks: 3-4 weeks of consistent use
  • Sun damage spots: 6-8 weeks
  • Old stubborn pigmentation: 8-12 weeks
  • Melasma: May reduce appearance but unlikely to fully clear with natural treatments alone

Consistency matters more than concentration. Apply 3-4 times per week and always use sunscreen during the day — UV exposure undoes all progress.
