What Is Kojiglo Gel?

Kojiglo Gel is a topical depigmenting gel from Glenmark containing kojic acid 2%. It comes in a 20 g tube. Kojic acid (5-hydroxy-2-(hydroxymethyl)-4H-pyran-4-one) is a natural compound originally isolated from Aspergillus oryzae, the fungus used to produce sake and soy sauce in traditional Japanese fermentation. It has been used as a topical depigmenting agent in dermatology since the 1980s and is widely available globally either as prescription-strength preparations or in over-the-counter cosmeceuticals.

How Does Kojic Acid Work?

Kojic acid produces skin lightening through three complementary mechanisms:

• Tyrosinase inhibition — kojic acid chelates the copper at the active site of tyrosinase, the rate-limiting enzyme in melanin biosynthesis. Less tyrosinase activity means less melanin produced by melanocytes.
• Antioxidant activity — kojic acid scavenges free radicals generated by UV exposure, indirectly reducing UV-driven melanocyte stimulation.
• Mild antibacterial and antifungal activity — useful in patients whose hyperpigmentation is associated with low-grade inflammatory skin conditions.

Compared to hydroquinone (the reference depigmenting agent), kojic acid is approximately 10-times less potent on a per-percent basis — but better tolerated, with a much lower rate of contact dermatitis and effectively zero risk of exogenous ochronosis (the irreversible blue-grey discolouration that limits long-term hydroquinone use).

Visible lightening typically appears at 4–8 weken; peak effect at 3–6 months of consistent daily use plus rigorous SPF.

Toepassingen en Indicaties

• Melasma (chloasma) — symmetric brown patches on cheeks, forehead, upper lip, often hormonally driven; particularly useful for sensitive-skin patients who don’t tolerate hydroquinone
• Post-inflammatory hyperpigmentation (PIH) after acne, eczema, or burns — especially on Fitzpatrick III–VI skin where PIH is most prominent
• Solar lentigines (sun spots, age spots)
• Freckles (ephelides) — modest effect
• Maintenance therapy after a hydroquinone or Kligman-triple cycle — gentler than HQ for indefinite use
• Zwangerschap en borstvoeding — commonly used as the safer depigmenting choice when HQ is contraindicated (although topical retinoids must still be avoided)

Kojiglo Gel is niet for: deep dermal-pigment melasma (laser or chemical peel), broken or eczematous skin, or as a substitute for sun protection.

Kojiglo Gel Dosage and How to Apply

Kojiglo Gel comes in a 20 g tube at 2% kojic acid.

How to Apply Kojiglo Gel Properly

1. Was voorzichtig with a mild non-foaming cleanser, then pat dry. Wait 10–15 minutes.
2. Patch test first — apply a small amount to the inner forearm for 24–48 hours before facial use. Kojic acid causes contact dermatitis in 3–5% of users.
3. Apply a thin film to the dark patches only — not to the entire face. Avoid surrounding healthy skin to prevent demarcation lines.
4. Avoid eyes, mouth corners, lips, mucous membranes, eyelids.
5. Once or twice daily — start at once daily (typically nightly), increase to twice daily if tolerated.
6. Daily broad-spectrum SPF 50+ in the morning is essential — UV exposure undoes kojic acid's effect within days. Reapply every 2–3 hours outdoors. Wide-brimmed hat. Avoid tanning beds entirely.
7. Course duration — kojic acid can be used continuously for 3–6 months, then a break of 4–8 weeks before resuming. Long-term use is generally acceptable but maintenance is best done with intermittent rather than continuous application.
8. Stop immediately if persistent stinging, contact dermatitis, or rebound darkening develops.

Side Effects of Kojiglo Gel

Common (mild, settles in 1–2 weeks):

• Mild stinging, burning, or tingling on application — especially in the first week
• Erythema (mild redness) of treated areas
• Mild dryness or peeling
• Mild photosensitivity — emphasises the SPF-50+ rule

Minder vaak maar belangrijk:

• Contactdermatitis (3–5% of users) — eczematous reaction at the application site. Stop and switch agent.
• Persistent erythema or post-inflammatory hyperpigmentation paradoxically caused by irritation — reduce frequency or stop temporarily

Unlike hydroquinone, kojic acid does not cause exogenous ochronosis (the irreversible blue-grey discolouration). This is its major safety advantage for long-term use.

Contraindications and Warnings

• Hypersensitivity to kojic acid
• Active eczema, dermatitis, or broken skin in the area to be treated — treat the inflammation first
• Active herpes labialis (cold sores) — defer until resolved
• Children <12 — not generally indicated; if needed, paediatric dermatology supervision
• Zwangerschap en borstvoeding — topical kojic acid has minimal systemic absorption and is generally considered safe; commonly used as the depigmenting agent of choice when hydroquinone is contraindicated

Geneesmiddelinteracties

Topical kojic acid has minimal systemic absorption and no clinically significant systemic drug interactions. Local interactions to manage:

• Other topical depigmenting agents (hydroquinone, arbutin, tretinoin, azelaic acid) — can be combined under dermatologist guidance for synergistic effect, but increase irritation risk; introduce one at a time
• Topicale retinoïden (tretinoin, adapalene, tazarotene) — commonly combined; apply at separate times of day (retinoid evening, kojic acid morning) to minimise irritation
• Chemical peels and microdermabrasion — pause kojic acid for 1–2 weeks before and after to reduce risk of post-procedure irritation
• SPF / sunscreens — mandatory companion product

How Kojiglo Gel Compares to Alternatives

Opslag en houdbaarheid

Store Kojiglo Gel below 25°C in the original tube, away from direct sunlight (kojic acid is light-sensitive). Replace the cap tightly after each use. Keep out of reach of children. Use within the manufacturer-stated period after first opening (typically 6 months) or before the printed expiry date, whichever is sooner.

Veelgestelde vragen

Is kojic acid safer than hydroquinone?

Yes — kojic acid is gentler, has a much lower rate of contact dermatitis, and effectively zero risk of exogenous ochronosis (the irreversible blue-grey discolouration that limits long-term hydroquinone use). The trade-off is that kojic acid is roughly 10× less potent on a per-percent basis — results take longer and are more modest. For mild-to-moderate melasma or PIH, kojic acid is often the right choice. For severe melasma, hydroquinone or Kligman-triple is more effective.

Hoelang duurt het voordat ik resultaten zie?

Visible lightening typically appears at 4–8 weeks of consistent daily application plus rigorous SPF. Peak effect at 3–6 months. If there is no visible improvement at 12 weeks, switching to a stronger agent (HQ or Kligman triple under medical supervision) may be appropriate.

Can I use Kojiglo Gel during pregnancy?

Topical kojic acid has minimal systemic absorption and is generally considered safe in pregnancy and breastfeeding. It is commonly used as the depigmenting agent of choice during pregnancy when hydroquinone (avoid in pregnancy) and topical retinoids (avoid in pregnancy) are contraindicated. Always confirm with your obstetrician or dermatologist before starting any topical treatment in pregnancy.

Can I combine kojic acid with vitamin C or niacinamide?

Yes — kojic acid combines well with topical vitamin C (L-ascorbic acid 10–20%) and niacinamide (4–5%) for enhanced depigmenting and antioxidant effect. Apply at separate times to minimise pH-related interactions: vitamin C in the morning under SPF, niacinamide and kojic acid in the evening.

Will kojic acid bleach my whole face if it touches healthy skin?

Kojic acid is well-targeted to active melanocyte sites — it lightens pigmented patches more effectively than normal-skin areas. Some lightening of normal surrounding skin can occur with prolonged extensive use, producing a slight demarcation around the treated patches. To minimise this, apply only to the dark patches, not to the entire face.

Why do I need SPF if I am using kojic acid at night?

UV exposure stimulates melanocytes to produce more melanin, undoing kojic acid's effect within days. Without daily broad-spectrum SPF 50+, kojic acid (and any other depigmenting agent) is essentially powerless. SPF is not optional; it is the primary therapy — the depigmenting agent is the adjunct.

Is Kojiglo Gel a permanent fix for melasma?

No depigmenting agent is a permanent fix for melasma — the underlying tendency to overproduce melanin remains. With consistent SPF, hormonal stability, and intermittent maintenance therapy, results can be sustained for years. Stopping treatment OR stopping SPF will gradually allow the melasma to return.
