Rice Ferment Filtrate (often Saccharomyces/Rice Ferment Filtrate) is a fermentation-derived ingredient rich in amino acids, vitamins, and minerals that helps hydrate and condition skin while providing mild antioxidant benefits. It is commonly used in moisturizing and brightening formulations.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
Glyceryl glucoside is a naturally occurring sugar-glycerol compound used in skincare as a humectant that attracts and binds water to the skin. It is also studied for its ability to stimulate aquaporin water-channel expression, supporting skin hydration and barrier function.
Tocopherol (vitamin E) is a lipid-soluble antioxidant used in skincare to protect skin and formulations from oxidative damage caused by free radicals and UV exposure. It also functions as a skin-conditioning and emollient agent and can stabilize oils against rancidity.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Skin dryness or tightness | Common | Soap-based surfactants derived from it can strip natural oils, especially with frequent use. |
| Skin irritation | Uncommon | May cause mild irritation in sensitive individuals or at higher concentrations. |
| Comedogenicity (pore clogging) | Uncommon | Considered moderately comedogenic; may contribute to breakouts in acne-prone skin. |
| Allergic contact dermatitis | Rare | Sensitization is infrequent but has been reported. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Dryness or tightness | Common | Can disrupt the skin barrier and strip natural oils with frequent use. |
| Chemical burns | Rare | Occurs primarily with concentrated raw material or improper formulation, not in finished consumer products. |
| Eye irritation or injury | Uncommon | Risk with accidental contact, particularly with cleansers near the eye area. |
| Mild skin irritation or stinging | Common | More likely at higher concentrations or on compromised/sensitive skin |
| Irritant contact dermatitis | Uncommon | Non-allergic irritation, often dose-dependent |
| Worsening of pre-existing eczema or barrier-impaired skin | Rare | Penetration-enhancing effect may increase reactivity |
| Systemic toxicity from topical use | Very rare | Reported mainly with extensive application on broken skin, especially in infants or burn patients |

| Ingredient | What it does |
|---|---|
| Aqua Solvent / vehicle | Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery. |
| Myristic Acid Surfactant/cleansing agent | Myristic acid is a saturated fatty acid commonly used in skincare as a cleansing and emulsifying agent, often reacted with alkalis to form soap-based surfactants. It contributes to foaming and texture in cleansers and other formulations. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Potassium Hydroxide pH adjuster / saponifying agent | Potassium hydroxide is a strong alkaline compound used in cosmetics to adjust pH and to saponify fatty acids in the production of liquid soaps and cleansers. At regulated low concentrations in finished products it is considered safe, functioning as a formulation aid rather than an active treatment. |
| Propylene Glycol Humectant / solvent | Propylene glycol is a small glycol molecule widely used in skincare as a humectant, solvent, and penetration enhancer that helps attract water and dissolve other ingredients. It is considered a base/formulation ingredient rather than a therapeutic active. |
| Stearic Acid Emulsifier / thickener | Stearic acid is a saturated long-chain fatty acid widely used in cosmetics as an emulsifier, thickening agent, and emollient to stabilize creams and lotions. It is generally considered a base/formulation ingredient rather than a therapeutic active. |
| Decyl Glucoside Surfactant/Cleanser | Decyl Glucoside is a mild, non-ionic surfactant derived from glucose and fatty alcohols, commonly used as a gentle cleansing and foaming agent in shampoos, facial cleansers, and baby care products. It is valued for its biodegradability and low irritation potential compared to harsher surfactants. |
| Lauric Acid Cleansing/surfactant & emollient fatty acid | Lauric acid is a medium-chain saturated fatty acid commonly derived from coconut or palm kernel oil, used in skincare as a cleansing agent, emulsifier, and emollient. It also has documented antimicrobial activity, particularly against Cutibacterium acnes. |
| Glycol Stearate Emollient / opacifying agent | Glycol stearate is the ester of ethylene glycol and stearic acid, used in cosmetics as an emollient, thickener, and pearlescent opacifying agent. It improves texture and gives products a smooth, creamy appearance. |
| Glyceryl Stearate Emulsifier/emollient | Glyceryl Stearate is a glycerol ester of stearic acid widely used as a non-ionic emulsifier and emollient to stabilize oil-in-water formulations and improve skin feel. It functions as a base/formulation ingredient rather than a therapeutic active. |
| Sodium PCA Humectant | Sodium PCA (sodium pyrrolidone carboxylic acid) is the sodium salt of pyroglutamic acid and a component of the skin's natural moisturizing factor (NMF). It is widely used in cosmetics as a water-binding humectant to hydrate and soften the skin. |
| Phenoxyethanol Preservative | Phenoxyethanol is a widely used broad-spectrum preservative that protects cosmetic and skincare formulations from bacterial and fungal contamination. It is typically used at concentrations up to 1% and serves as a formulation/base ingredient rather than an active treatment. |
