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%.
Tranexamic acid is a synthetic lysine derivative used topically to reduce hyperpigmentation, melasma, and post-inflammatory dark spots by inhibiting the plasminogen-plasmin pathway and reducing melanin transfer to keratinocytes. It is also valued for helping calm redness and improve uneven skin tone.
Citrus paradisi (Grapefruit) Fruit Extract is a botanical derived from grapefruit, valued for its vitamin C, flavonoid, and natural acid content, contributing antioxidant and mild astringent or brightening effects in skincare. It is commonly used as a conditioning and fragrance-contributing additive in cosmetic formulations.
Saccharum Officinarum (Sugarcane) Extract is derived from sugarcane and contains natural sugars and glycolic acid, contributing humectant and mild exfoliating properties. It is often included in skincare for hydration and to support gentle surface renewal.
Adenosine is a nucleoside that signals through cell-surface receptors to promote dermal fibroblast activity and collagen/elastin production, helping reduce the appearance of fine lines and wrinkles. It also has anti-inflammatory and soothing properties at low concentrations commonly used in cosmetics (around 0.04-0.1%).
Cyanocobalamin is a synthetic form of vitamin B12 occasionally included in topical skincare formulations, where it may serve as a coloring agent (imparting a pink-red hue) or as a conditioning additive. Some research has explored topical B12 for inflammatory skin conditions such as atopic dermatitis.
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 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. |
| Allergic contact dermatitis | Rare | Documented in patch-test studies but considered a relatively weak sensitizer. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Mild skin irritation | Uncommon | Transient redness or stinging, more likely on compromised or sensitive skin. |
| Eye irritation | Uncommon | Can occur with direct contact in eye-area products. |
| Skin dryness | Common | High concentrations can strip natural oils and disrupt the skin barrier with repeated use. |
| Irritation or stinging | Common | More likely on compromised, sensitive, or already dry skin. |
| Barrier impairment | Uncommon | Frequent exposure may reduce barrier function and increase transepidermal water loss. |
| Contact dermatitis | Rare | Irritant or, less often, allergic reactions reported in susceptible individuals. |
| Worsening of conditions like eczema or rosacea | Uncommon | Can aggravate inflammatory or reactive skin types. |
