A treatment no one offers — purifying the tongue at the source, directly.
Zinc, prebiotics, spirulina, green tea, amla — precise, plant-based, lasting.
The Purifying Tongue Serum is the most unique product in The Smilist range — and probably one of the rarest on the natural oral care market. Where a tongue scraper mechanically removes surface deposits, this serum works deeply on the source of the problem: anaerobic bacteria that colonize the tongue and produce the sulfur compounds responsible for bad breath and a coated or whitish tongue. A targeted formula, reaching where no toothpaste or mouthwash truly can.
The texture is gelled, fine, and easy to spread — a few drops applied directly to the tongue after brushing, without rinsing. The Zinc + Prebiotic complex neutralizes pathogenic bacteria and rebalances the tongue microbiota. Spirulina — an exceptional microalga rich in proteins, vitamins, and antioxidants — supports the vitality and regeneration of oral tissues. The green tea and amla (Indian gooseberry, one of the richest plants in vitamin C) duo provides powerful antioxidant protection against oxidative stress on the mucous membranes. Savory water purifies. Solidago cleanses. Organic sunflower oil protects. And menthol leaves a clean, plant-based freshness that lasts.
The Purifying Tongue Serum is for those who want truly clean breath — not masked, not fragranced, but purified at the source.

Maison Diaphane's Take
A discreet but essential step, to purify the tongue and reveal a deep, natural freshness. The Purifying Tongue Serum is The Smilist's most overlooked product — and yet one of the most effective for those who suffer from persistent bad breath despite serious oral hygiene. Spirulina in a tongue care product is a true formulation originality. To be systematically combined with the Professional Tongue Scraper for a complete tongue protocol.

What's the difference between this serum and the Professional Tongue Scraper?
The Professional Tongue Scraper mechanically removes visible surface deposits — it's a physical cleaning action. The Purifying Tongue Serum acts chemically and biologically on the bacteria themselves — it neutralizes the microorganisms responsible for deposits and bad breath before they can re-form. The two are complementary: the tongue scraper cleans, the serum prevents and rebalances.
Why spirulina in a tongue care product?
Spirulina is one of the most concentrated sources of protein, vitamin B12, iron, and antioxidants in the plant kingdom. Applied topically to mucous membranes, it supports the cellular vitality of oral tissues and contributes to their resistance to bacterial aggressions — a nutritional approach to tongue health, rare in oral cosmetics.
Can bad breath return despite using the serum?
Persistent bad breath can have several causes — lingual (the most common), gingival, gastric, or nasal. The Purifying Tongue Serum addresses the lingual cause. If bad breath persists after several weeks of regular use, a dental or medical consultation is recommended to identify another underlying cause.
What is the complete The Smilist breath protocol?
Morning on an empty stomach: Professional Tongue Scraper → Purifying Oral Oil (30 sec) → Brushing + Purifying Freshness Toothpaste → Purifying Tongue Serum (no rinsing). Evening: Brushing + Toothpaste → Tongue Serum. A complete protocol that acts mechanically, biologically, and chemically on all sources of tongue imbalance.
