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%.
Acetyl glucosamine is an amino sugar that serves as a precursor to hyaluronic acid and can help support skin hydration and barrier function. It is also studied for its ability to reduce hyperpigmentation by inhibiting melanin production, often used alongside niacinamide.
Ascorbyl Glucoside is a stable, water-soluble vitamin C derivative that is enzymatically converted to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and skin brightening. It is generally considered milder and more stable than pure L-ascorbic acid.
Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products.
Boerhavia diffusa root extract is a plant-derived ingredient used in skincare for its antioxidant and soothing properties, traditionally sourced from the punarnava plant. It is incorporated into formulations to help mitigate oxidative stress and support skin barrier function.
Dipotassium glycyrrhizate is a water-soluble salt derived from licorice root (glycyrrhizic acid) used in skincare for its anti-inflammatory, soothing, and antioxidant properties. It is commonly added to formulations to calm irritation, redness, and sensitivity.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| 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. |
| Allergic contact dermatitis | Very rare | Documented in isolated case reports; true sensitization is unusual. |
| Mild transient irritation or stinging | Uncommon | Typically mild and resolves with continued use or reduced frequency. |
| Erythema (redness) | Rare | Generally seen in sensitive skin or with high concentrations. |
| Mild transient stinging or tingling | Uncommon | More likely at higher concentrations or on sensitive skin |
| Dryness or mild irritation | Rare | Can occur depending on formulation and pH |
| Mild transient stinging or irritation | Uncommon | More likely on broken or compromised skin or at high concentrations. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Oxidation-related sensitization | Very rare | Unsaturated phospholipids can oxidize, potentially yielding irritant by-products. |
| Redness or dryness in low-humidity environments | Uncommon | Can draw moisture from skin if ambient humidity is very low and not sealed with an occlusive. |
| Hypersensitivity reactions with injectable forms | Very rare | Relevant mainly to dermal filler use, not topical cosmetic application. |

It improves skin hydration and aids the delivery and stability of other ingredients. |
| Caprylyl Glycol Humectant / skin-conditioning agent and preservative booster | Caprylyl glycol is a multifunctional emollient and humectant derived from caprylic acid that helps hydrate skin and enhance the efficacy of preservatives in formulations. It is widely used as a stabilizing and conditioning base ingredient rather than a therapeutic active. |
| 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. |
