Snail Truecica Miracle Repair Toner

A filtrate of garden snail mucus containing glycoproteins, hyaluronic acid, allantoin and glycolic acid. A handful of small industry-funded trials report improved hydration and reduced fine lines after several weeks of use, but independent, well-controlled human data are scarce, so treat the "repair" and "glass skin" marketing as unproven rather than false.

A form of vitamin B3 used to support a more even-looking tone and a comfortable barrier. Well tolerated at cosmetic levels.

A light, low-odor glycol used as a solvent and humectant, extremely common in Korean toners and essences. It has a low reported irritation rate and is graded low concern in published assessments.

A urea derivative used as a humectant to help skin retain moisture and improve hydration. Published safety assessments find it well tolerated at the use levels in cosmetics.

A plant extract long used in traditional wound care and now common in "cica" soothing products, valued for calming redness and supporting the skin barrier. It is generally well tolerated, with rare contact allergy reported.

Tea tree oil is used for its antimicrobial reputation in blemish-focused products, but it is a genuine, well-documented contact sensitizer, and its allergy potential rises sharply once the oil has oxidized from air exposure. Fresh, well-preserved, low-concentration formulations are much lower risk than old or improperly stored oil.

Lavender essential oil naturally contains linalool, geraniol, and coumarin, several of the recognized fragrance allergen constituents, so it can trigger contact reactions in fragrance-sensitive users even though it is a "natural" ingredient. It is not a general hazard for most people, but those with a known fragrance allergy should treat it like any other essential oil.

An aromatic plant extract rich in natural antioxidants, valued in skincare formulations for its protective properties. Published cosmetic assessments indicate it is generally well tolerated, though the botanical origin means some sensitive individuals may react.

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.

A soothing plant extract traditionally used in skincare, valued for its potential anti-inflammatory properties. Published assessments note it is generally well tolerated in cosmetic formulations, though people with sensitivities to botanicals may want to patch test.

An extract from the root of the baical skullcap plant, used for antioxidant and skin-conditioning effects. It is generally well tolerated at cosmetic concentrations.

Large, water-binding polysaccharides derived from connective tissue, used to support hydration and skin firmness. They are inert polysaccharides with no known contact allergens or sensitization potential, and their size and chemistry make significant systemic absorption unlikely.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

A soothing, skin-conditioning compound (also found in comfrey root) commonly added to calm and hydrate irritated or sensitive skin. It has a long history of safe use with very low irritation potential.

Arbutin is a plant-derived brightening ingredient that is chemically related to hydroquinone and can release small amounts of it in formulation. EU regulators have set new maximum use levels for arbutin and alpha-arbutin in leave-on products because of this hydroquinone-release concern, so products sold there must stay within those caps.

A naturally occurring nucleoside used in anti-aging formulas, often marketed for smoothing the look of fine lines. It has a low irritation profile and no established hazard at cosmetic use levels.

A naturally occurring tripeptide (amino acid compound) that functions as a cellular antioxidant. It is graded low concern in cosmetic assessments, though absorption across intact skin appears limited.

A purified triterpene from Centella asiatica (the "cica" plant) used in soothing and barrier-support products, especially Korean formulas. It is well tolerated with a low reported irritation rate; the strong repair and anti-aging claims around it are more marketing than settled evidence.

A key active compound from Centella asiatica linked in published research to skin barrier support and soothing properties. It is well tolerated in skincare formulations.

A triterpenoid from Centella asiatica associated in published studies with skin resilience and wound-healing support. It is generally well tolerated in cosmetic concentrations.

A triterpenoid from Centella asiatica with published research linking it to skin barrier function and calming effects. It appears well tolerated at cosmetic levels.

The base most products are built on. It carries the other ingredients and has no safety concern.

A glycerin-derived humectant and solvent that helps retain water in the skin and dissolve other cosmetic ingredients. It is well tolerated across skin types in the concentrations used in cosmetics.

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

A volatile ketone used as a fragrance component that occurs naturally in raspberries. Dermatological testing in cosmetics is limited, though it is recognized as safe by regulatory bodies when used in fragrance applications. Fragrance components can trigger reactions in sensitive individuals.

A citrus-scented fragrance component. Fine for most, but it oxidizes over time into a known contact allergen, so it must be labelled in the EU.
