The ones worth using
- Tea tree oil, diluted — comparable to low-strength benzoyl peroxide in small trials, though slower. Dilute to 5 percent, roughly two drops in a teaspoon of a carrier oil, and use as a spot treatment only. Never neat on skin.
- Neem — genuinely antibacterial. Use it as a face wash or a brief rinse from boiled, cooled leaves. Oral neem is not advised in pregnancy.
- Aloe vera — calms inflammation and speeds healing of picked or inflamed spots. Use plain gel from the leaf or a preservative-only product; avoid the neon green fragranced gels.
- Green tea — cooled brewed tea used as a toner mildly reduces oil and inflammation.
- Turmeric, used correctly — anti-inflammatory, but only in a paste that stays moist, applied for ten minutes and rinsed. It stains, so use a tiny amount with curd or honey.
- Honey — mildly antibacterial and humectant, and safe as a short mask.
The ones to stop
Lemon juice is the most damaging popular remedy for Indian skin. It is strongly acidic, phototoxic, and reliably produces dark patches on skin types IV to VI — the exact opposite of the intended result. Baking soda destroys the skin's acid mantle. Toothpaste burns. Undiluted essential oils, especially cinnamon, clove and oregano, cause chemical irritation. Multani mitti and besan packs left on until they crack pull water out of the skin and leave it tight and inflamed, which worsens acne in the following week.
How to use a herbal remedy safely
Patch-test on the inner forearm for three consecutive evenings. Use one new thing at a time, no more than twice a week to begin with. Keep contact times short — ten minutes for a mask, not until dry. Rinse with plain lukewarm water. And stop at the first sign of stinging, which is not a sign it is working.
Where herbal remedies fall short
Home remedies work on mild, surface breakouts. They do not resolve deep cystic acne, and delaying treatment of cystic acne means scarring that is far harder to fix than the acne itself. If you have painful lumps under the skin, spots that keep recurring in the same place, or any scarring, see a dermatologist — azelaic acid and topical antibiotics are safe in pregnancy and far more effective.
Anything taken by mouth is a different question entirely. Herbal supplements are not standardised, and several common ones affect the uterus or hormone levels. Never start an oral herbal course for skin during pregnancy without clearing it with your obstetrician.
