Licostrata

Hydroquinone, the active ingredient in Licostrata, is a skin depigmenting agent presented as a topical formulation for topical use. It is employed to reduce excess melanin in conditions such as melasma, age spots and post‑inflammatory hyperpigmentation. GNH USA supplies Licostrata as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Hydroquinone is used in dermatology to address hyperpigmentation disorders. - Melasma: lightens dark patches on the face caused by hormonal influences. - Age spots: reduces the appearance of sun‑induced lentigines. - Post‑inflammatory hyperpigmentation: fades discoloration after skin injury or inflammation. - Other hyperpigmentation disorders: improves uneven skin tone in various pigmentary conditions.

Hydroquinone may cause a range of skin reactions, from mild irritation to rare severe events.

Common Side Effects: - Skin irritation: redness, itching or burning at the application site. - Dryness: flaking or peeling of treated skin. - Mild erythema: temporary redness. - Hyperpigmentation rebound: darkening after discontinuation. - Contact dermatitis: allergic skin reaction. - Pruritus: localized itching.

Serious or Rare Side Effects: - Exogenous ochronosis: bluish‑black discoloration with prolonged use. - Severe allergic reaction: swelling, hives or difficulty breathing. - Skin ulceration: breakdown of skin integrity. - Persistent depigmentation: lasting loss of normal skin colour. - Photo‑sensitivity: increased sunburn risk. - Systemic absorption effects: unlikely but reported in extensive use.

When using Licostrata, consider the following safety measures. - Avoid application on broken or inflamed skin: may increase irritation. - Limit sun exposure: hydroquinone can heighten photosensitivity; use sunscreen. - Do not use on large body areas: risk of systemic absorption. - Discontinue if severe irritation occurs: seek medical advice. - Pregnancy and breastfeeding: safety not established; avoid unless prescribed. - Store at below 25°C: keep in the original container, protect from moisture and direct sunlight.

Hydroquinone can interact with other topical agents and systemic drugs.

Major Interactions (Avoid):\n- Concurrent use with other depigmenting agents (e.g., tretinoin, corticosteroids) without medical supervision: may increase irritation. - Application with strong chemical peels: heightened risk of burns.

Moderate Interactions (Monitor Closely): - Use with photosensitizing drugs (e.g., tetracyclines, retinoids): monitor for increased sun sensitivity. - Combination with other skin lighteners: adjust frequency to reduce adverse effects. - Interaction with systemic antioxidants: may alter efficacy, observe response.
