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%.
Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
Gluconolactone is a polyhydroxy acid that gently exfoliates the skin surface, provides antioxidant and humectant benefits, and is often considered milder than alpha hydroxy acids. It is well tolerated, including by sensitive skin, due to its larger molecular size and slower penetration.
Phytosphingosine is a naturally occurring sphingolipid that helps maintain the skin barrier and also exhibits antimicrobial and anti-inflammatory properties. It is commonly incorporated into moisturizers and barrier-repair formulations to support ceramide synthesis and skin integrity.
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 or eye irritation | Uncommon | Generally mild; more likely at higher concentrations or in leave-on or sensitive-eye applications. |
| Allergic contact dermatitis | Rare | Sensitization is often attributed to manufacturing impurities such as amidoamine or dimethylaminopropylamine rather than the surfactant itself; cross-reactivity with cocamidopropyl betaine is reported. |
| Mucosal or scalp stinging | Rare | Transient and typically resolves on rinsing. |
| 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. |
| Skin irritation or dryness | Uncommon | More likely at higher concentrations or with prolonged contact, though milder than sulfates. |
| Eye irritation | Uncommon | Can cause stinging if formulations contact the eyes. |
| Mucosal irritation in oral products | Rare | Occasionally noted with toothpaste use in sensitive individuals. |
| Mild transient flushing or redness | Uncommon | More likely at higher concentrations or in sensitive skin; usually subsides quickly. |
| Tingling, stinging, or burning sensation | Uncommon | Often associated with higher percentages or compromised barrier. |
| Contact irritation or itching | Rare | Generally dose-dependent and resolves with discontinuation. |

| 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.
