The strongest dark spot remover most people remember is no longer on drugstore shelves. According to the FDA, over-the-counter skin lightening products containing hydroquinone could no longer be legally marketed in the US after September 23, 2020, following changes in the CARES Act. The agency says there are no FDA-approved OTC hydroquinone products now, and it has warned about serious side effects reported with unapproved ones, including rashes, facial swelling and ochronosis, a permanent skin discoloration.

That is why the dark spot remover aisle looks the way it does. Instead of hydroquinone, today's serums use ingredients like vitamin C, niacinamide, alpha arbutin, tranexamic acid, azelaic acid and exfoliating acids, often several at once. They fade spots from sun, breakouts and hormones gradually, usually over weeks rather than days.

None of it works without sunscreen. UV keeps darkening the same spots you are trying to fade, so daily SPF is the most important product in this edit, even though it is the least exciting one.

The first grid is dark spot serums. The second is toners, spot treatments, peels and SPF. My tip: introduce one active at a time, give it several weeks, and take a photo in the same window light each week so you can actually see progress.

Sunday Riley Good Genes is the most reviewed product in this edit. It is a lactic acid serum that exfoliates rough skin and brightens quickly, which makes it a good first step if your spots sit under dull texture. EADEM Milk Marvel is a milky serum with vitamin C and niacinamide for dark spots and post-acne marks, and it has the best rating in this grid. Caudalie Vinoperfect is sold as a vitamin C alternative and targets spots from sun, acne or pregnancy.

Glow Recipe Guava Vitamin C uses five forms of vitamin C plus tranexamic and ferulic acids. Murad Rapid Dark Spot Correcting Serum is a multi-acid formula with vitamin C that Murad says visibly fades spots in seven days. Kiehl's Clearly Corrective is a vitamin C serum for spots and post-acne marks, best for oily to normal skin.

The Ordinary Alpha Arbutin 2% + Hyaluronic Acid is the simplest formula here, one targeted ingredient in a light serum. Topicals Faded is made to be safe for all skin tones and shades, and it targets stubborn discoloration and post-blemish marks.

What I would skip: layering three brightening serums at once. Pick one, and if you add an exfoliating acid, use it on alternate nights so your skin barrier stays calm.

Kiehl's Better Screen UV Serum SPF 50+ is the most reviewed product in this grid and the one I would buy first. It is a light serum sunscreen with a collagen peptide, easy to wear under makeup every morning.

Dermalogica PowerBright Dark Spot Peel has the best rating in this edit. It is an at-home peel with 12% AHA for surface spots from UV, breakouts and melasma, so use it weekly, not daily. Paula's Choice 6% Mandelic Acid + 2% Lactic Acid is a gentle leave-on exfoliant that smooths texture and fades spots. Farmacy Brighten Up is a 3% tranexamic acid toner with azelaic acid and 5% PHA.

For spot treatment, EADEM The Mark is a concentrated cream you place directly on dark spots and blemishes, with visible fading in as little as two weeks. Topicals Faded Patches are tranexamic acid patches that the brand says fade the look of hyperpigmentation in six hours and help prevent marks after a breakout. The INKEY List Tranexamic Acid is a nighttime treatment for uneven patches.

Reframe Pigment Processor is a Korean-made smart serum that pairs pigment-targeting actives with barrier support.

What I would skip: a peel and a strong acid toner in the same week. Rotate them, and never skip SPF the morning after.

I think the best dark spot remover routine is patient and boring. One brightening serum, one gentle exfoliant a few nights a week, and sunscreen every single morning. Hydroquinone is now a prescription conversation, so if spots do not budge after a few months, or melasma is involved, see a dermatologist. And if a spot changes shape, color or size, have it checked instead of trying to fade it. Fading takes time, but protecting what you have faded takes only a daily layer of sunscreen.
