One of these is something you do at home every night. The other is something done to you in a clinic every few weeks.
They are frequently offered as alternatives for melasma, and framing them that way is where people get into trouble. They do different halves of the job, and the order matters more than the choice.
Both work the pigment row, but from opposite ends. Hydroquinone acts on the cause — it shuts down the enzyme making new pigment. A peel acts on the result — it removes layers of skin that are already stained, which is also why it touches the barrier and inflammation rows in a way the cream does not. That inflammation is exactly the risk: in melasma, inflammation is itself a pigment trigger.
Preventing new pigment | Hydroquinone | Strong
Only the cream does this. A peel has no ongoing effect once you leave the clinic.
Removing pigment already there | Chemical peel | Moderate
A peel lifts stained surface layers faster than any cream, which is why results can look dramatic early.
Speed of visible change | Chemical peel | Moderate
Days versus weeks. This is the appeal, and also the trap.
Durability | Hydroquinone | Consensus
Peel results fade as pigment returns, unless a cream routine is holding the line underneath.
Melasma specifically | Hydroquinone first | Consensus
Melasma is a condition of overactive pigment cells, not just stained skin. Removing the stain without calming the cells invites it back.
Safety in deeper skin tones | Hydroquinone, with limits | Moderate
This is the sharpest warning on this page. Medium and deep peels carry a real risk of making pigment worse in deeper skin tones. Superficial peels are much safer, but still need an experienced hand. Meanwhile hydroquinone's own limitation — the small risk of blue-gray discoloration with long unbroken use — is also more often reported in deeper tones. Neither option is risk-free here, which is why supervision matters.
Cost | Hydroquinone | —
A prescription tube versus a series of clinic visits.
Sun damage and general dullness | Chemical peel | Moderate
If the goal is overall brightness and texture rather than melasma specifically, a peel does more.
The standard approach is both — in a specific order.
Never do step 2 without step 1 if you have melasma. Peeling untreated, actively inflamed melasma is one of the most common ways it gets worse.
Sunscreen is not optional here — it is the treatment. A tinted mineral sunscreen with iron oxides blocks visible light, which drives melasma in a way that ordinary clear sunscreens do not fully address. Peeling without daily sun protection is close to pointless.
Realistic expectation: melasma is chronic and relapsing. The goal of both treatments is control, not cure.
