Ascorbic acid (vitamin C) is a water-soluble antioxidant used in skincare to neutralize free radicals, inhibit melanin synthesis, and support collagen production. It is valued for brightening, evening skin tone, and protecting against photodamage when used alongside sunscreen.
Punica Granatum (pomegranate) Extract is a botanical ingredient rich in polyphenols, ellagic acid, and punicalagins used in skincare for its antioxidant and anti-inflammatory properties. It is studied for protecting against oxidative stress and supporting skin barrier function.
Glutathione is a tripeptide antioxidant used in skincare for its melanin-modulating and antioxidant properties, often promoted to reduce hyperpigmentation and even skin tone. Topical efficacy data is limited and variable, with stronger systemic effects associated with oral or intravenous routes.
Ferulic acid is a plant-derived phenolic antioxidant that neutralizes free radicals and helps protect skin from UV-induced oxidative damage. It is frequently combined with vitamins C and E to enhance their stability and photoprotective effect.
Lactic acid is an alpha-hydroxy acid that exfoliates the skin by loosening bonds between corneocytes, promoting cell turnover, and acting as a humectant to improve hydration, texture, and tone. It is commonly used at concentrations ranging from low (hydration) to higher peel-strength formulations.
Hyaluronic acid is a glycosaminoglycan that attracts and binds water to the skin, helping to maintain hydration and improve the appearance of plumpness and smoothness. It is widely used in moisturizers and serums and is generally well tolerated across skin types.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Mild stinging or tingling on application | Common | More likely at higher concentrations or low pH, and on sensitive or compromised skin. |
| Transient redness (erythema) | Uncommon | Usually temporary and resolves after acclimation or reducing frequency. |
| Dryness or skin irritation | Uncommon | Can occur with frequent use or in combination with other actives. |
| Allergic contact dermatitis | Rare | True hypersensitivity to ascorbic acid is infrequent; patch testing can confirm. |
| Yellow-orange skin staining from oxidized product | Rare | Caused by degraded (oxidized) formulations rather than the fresh active itself. |
| Mild skin irritation or redness | Uncommon | May occur in sensitive individuals or with higher concentrations. |
| Contact urticaria | Very rare | Isolated reports linked to pomegranate sensitivity, sometimes associated with food allergy cross-reactivity. |
| Contact allergic reaction | Rare | Sensitization to the ingredient or formulation components is possible. |
| Skin lightening beyond intended areas / uneven results | Rare | Reported mainly with systemic use rather than topical. |
| Serious adverse events such as skin rashes, organ effects, or Stevens-Johnson syndrome | Very rare | Primarily linked to intravenous/injectable use, which lacks regulatory approval for skin lightening in many regions. |
| Mild transient skin irritation or stinging | Uncommon | More likely in formulations with low pH or in sensitive skin |
| Redness or erythema | Uncommon | Usually mild and resolves after discontinuation |
| Discoloration of product (yellowing/oxidation) | Common | A stability issue rather than a skin reaction; does not indicate harm |
| Skin dryness or flaking | Common | Result of accelerated exfoliation, especially when overused. |
| Erythema (redness) | Common | Usually temporary; more pronounced with higher strengths. |
| Increased photosensitivity | Common | AHAs heighten UV sensitivity; daily sunscreen is advised. |
| Irritant contact dermatitis | Uncommon | Burning, itching, or persistent redness, often from overuse or high concentration. |
| Post-inflammatory hyperpigmentation | Uncommon | More likely in darker skin tones following irritation. |
| Chemical burn or blistering | Rare | Associated with high-concentration peels or prolonged contact. |
