For every woman with a bathroom cabinet full of once-used products, it's clear finding a skin care regimen that fulfills individual needs is not an easy process. We all want to find that one magic product that does wonders for both our complexion and our self-esteem. And for many women who suffer from hyperpigmentation -- a darkening of the skin caused by overproduction of melanin resulting in patchy dark areas or small spots -- this requires a do-it-all brightening serum and dark spot corrector.

Equitance Brightening Serum & Spot Corrector, $125, is said to immediately moisturize the skin and make it appear brighter within days of use, while breaking up hyperpigmentation in as little as four weeks. With its impressive clinical studies and patented technology and ingredients, it made us eager to see the results. We asked TotalBeauty.com reviewers to try out the product and tell us: Can one serum do all that? Here's what our reviewers have to say.

Sun damage, hormonal changes, a stubborn pimple or even a mosquito bite can cause hyperpigmentation, leaving spots that haunt you for days, weeks and even years. This serum promises that you can throw out your peels and resurfacing creams (go ahead and cancel that laser appointment while you're at it) for just one tube of product.

Equitance's patented delivery system uses microcapsules called liposomes to deliver the product's brightening ingredients, like linoleic acid, directly to your skin for noticeably brighter, more even tone. No doctor's office, no pain -- just a quick application of serum in the morning and evening.

"I haven't been using this product for very long, but I am already seeing great results! My skin is looking brighter, almost glow-y, and feels softer." --khumpinia

"I have been using [this serum] for almost a week, twice a day after washing my face, and my skin has taken pretty well to it. It has made my skin generally brighter and softer. Definitely worth a try!" --amanda_so

The ingredient label on most beauty products reads like a foreign language, and you're lucky if you can spot an ingredient you recognize. Equitance products are inspired by the natural beauty products Japanese women have used for centuries (i.e., you can actually read this label).

This serum utilizes the powerful combination of cherry blossom leaf extract from the Japanese sakura tree and shell ginger extract from the Japanese alpinia speciosa leaf to provide lightweight moisture while they brighten.

"My skin soaks it up and instantly feels softer and smoother. Plus, I can layer it under my BB cream and SPF. It doesn't leave my skin looking oily or splotchy by the end of the day." --ess_sun89

"A little bit of this product goes a long way, and I really like the smooth texture. It does not leave your skin feeling greasy, either. I am excited to continue to watch the texture and appearance of my skin improve." --beautyjunkie17
