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%.
Glycolic acid is an alpha-hydroxy acid derived from sugar cane that exfoliates by loosening bonds between dead skin cells on the surface, promoting cell turnover and improving texture, tone, and fine lines. It is one of the smallest AHAs, allowing relatively deep penetration into the skin.
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.
Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier.
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.
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 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. |

| 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. |
| 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. |
| Niacinamide Key active Cell-communicating / barrier-repair active | 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%. |
