FAQs
Q1. Enawish-HQ contains Hydroquinone alongside Glycolic Acid and Kojic Acid — why are so many depigmenting agents needed in one product?
A1. Each ingredient targets melanin production through a different mechanism, creating a multi-level attack on hyperpigmentation. Hydroquinone acts as a tyrosinase substrate inhibitor — it is taken up by melanocytes and competes with L-DOPA, halting melanin synthesis. Kojic Acid chelates the copper at the active site of tyrosinase, disabling the enzyme. Glycolic Acid and Lactic Acid (both AHAs) accelerate epidermal cell turnover, physically shedding pigmented corneocytes and improving penetration of the depigmenting agents. Licorice Extract's glabridin adds another tyrosinase-inhibition pathway. Layering these mechanisms is essential for treating stubborn melasma, where a single agent rarely achieves sustained clearance. This formulation requires dermatologist supervision — do not use without a prescription.
Q2. Why is sunscreen non-negotiable when using Enawish-HQ — what happens if I skip it?
A2. Hydroquinone and the AHAs in Enawish-HQ suppress the melanocyte's current activity, but without UV protection, UV radiation immediately re-activates melanocytes through the MC1R receptor. The net effect: the gel clears pigmentation at night while unprotected UV exposure during the day reverses that progress in real time — essentially running backwards on a treadmill. Beyond this futility, Hydroquinone itself is photosensitising, and UV exposure on skin currently undergoing HQ treatment can trigger paradoxical darkening (ochronosis risk with prolonged unsupervised use). Broad-spectrum SPF 50+ every morning is not optional — it is integral to the treatment protocol.
Q3. Is the Hydroquinone in Enawish-HQ safe for Indian skin tones with Fitzpatrick types III–VI?
A3. Hydroquinone 2–4% is the gold standard for treating melasma in guidelines across India, the US, and Europe precisely because its mechanism (tyrosinase inhibition) is effective across all skin tones. Indian skin tones (Fitzpatrick III–VI) benefit significantly from HQ for post-inflammatory hyperpigmentation (PIH) from acne, injuries, and hormonal melasma. The risk of exogenous ochronosis — a paradoxical blue-grey darkening from chronic unsupervised HQ use — is reported predominantly with high-concentration products used for years without medical oversight. Under a dermatologist's supervision with a defined treatment cycle and appropriate breaks, HQ is safe and effective for South Asian skin tones. Never use Enawish-HQ without ongoing dermatologist supervision.
Q4. Can Enawish-HQ be used on post-acne dark spots (PIH), or only for melasma?
A4. Enawish-HQ is effective for both conditions, though the mechanism varies slightly. Melasma involves constitutively overactive melanocytes driven by hormonal (especially oestrogen), UV, and genetic factors; PIH involves melanocytes activated by an inflammatory trigger (acne, injury, friction). The multi-mechanism formula addresses both: Hydroquinone and Kojic Acid reduce active melanogenesis, Salicylic Acid (which is also present) helps clear the comedonal blockage that causes the acne driving PIH, and the AHAs accelerate removal of surface pigmentation. For PIH from acne specifically, also address the acne itself — depigmenting agents cannot keep up with new PIH forming from ongoing breakouts.
Q5. How long should Enawish-HQ be used, and does pigmentation return after stopping?
A5. Standard dermatological protocols for Hydroquinone use recommend 3-month treatment cycles with breaks to prevent tolerance and reduce ochronosis risk. Many dermatologists use a step-down approach: HQ gel for 3 months to achieve clearance, then transition to maintenance with non-HQ brightening ingredients (Vitamin C, Niacinamide, Azelaic Acid) with ongoing SPF. Pigmentation can recur if sun protection is not continued after stopping HQ — melanocytes that have been suppressed can reactivate with UV or hormonal triggers. The goal of treatment is not permanent eradication but managed reduction with lifestyle modifications (SPF, avoiding triggers) to prevent return.
