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%.
Phenylethyl Resorcinol is a resorcinol-derivative tyrosinase inhibitor used to reduce melanin production, helping to fade hyperpigmentation and even skin tone. It is a potent active that requires careful formulation due to instability and oxidation potential.
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.
Capryloyl Salicylic Acid (also called LHA) is a lipophilic derivative of salicylic acid in which a fatty caprylic chain is attached, allowing slower, more targeted penetration into the skin. It is used as an exfoliant to promote desquamation, refine skin texture, and help manage acne and signs of photoaging.
Citrus Limon (lemon) fruit extract is derived from lemon and is used in skincare for its astringent, brightening, and antioxidant properties, largely attributed to its vitamin C and citric acid content. It is commonly included for toning and mild exfoliating effects.
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. |
| 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. |
| 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. |
| Skin dryness | Common | High concentrations can strip natural oils and reduce skin hydration. |
| Irritation or stinging | Common | Especially on compromised, sensitive, or freshly exfoliated skin. |
| Disruption of skin barrier | Uncommon | Repeated exposure may impair barrier function with frequent use. |
| Contact dermatitis | Rare | Irritant or allergic reactions reported in susceptible individuals. |
| Allergic contact dermatitis to ethanol itself | Very rare | True ethanol allergy is uncommon and documented in isolated cases. |
