If you haven’t heard of Bio-Oil yet, consider it your lucky day. The grapefruit-colored oil is secretly a skin care hero with a cult-like following.

It made its debut in 2002 as a scar and stretch-mark solution, but today, Bio-Oil ($24 for 6.7 oz) is a favorite among many thanks to its skin healing and repairing properties. "This product has changed my skin forever," raved an Amazon shopper of the multitasker. "The holy grails of oils," added another.

The formula is made with calendula, lavender, rosemary and chamomile oils and enriched with vitamins A and E to help restore skin. Together with PurCellin Oil, a proprietary oil blend, the plant extracts and vitamins deliver skin-nourishing benefits in a lightweight, non-greasy formula. According to the brand, it’s the number one scar and stretch mark product in 18 countries. And in a clinical study, 50 percent of subjects saw improvements of stretch marks in just eight weeks when applying Bio-Oil.

With more than 4,500 5-star reviews on Amazon, here's why shoppers swear by Bio-Oil.

Stretch marks

Stretch marks are a common side effect of pregnancy, weight gain and growth spurts. Those skin tears are permanent, but Bio-Oil's unique formula helps reduce accompanying itchiness and boost moisture to help skin appear more plump.

“Men don't like to talk about it, but we get stretch marks just the same as women do,” explained one man, who used Bio-Oil consistently for six months. “I've had some weight gain and loss since childhood, and it had left me with stretch marks that crippled my self-esteem.”

He continued: “The discoloring on my stretch mark scarring has changed and now looks a lot more unnoticeable. I will definitely use this further in hopes time and effort will completely heal over the marks. I highly recommend it for anyone suffering from scars that they feel will never be gone.”

Some new moms use it as a stretch mark preventative during pregnancy.

“After using this product I am so glad to say I don’t have a single stretch mark,” wrote a happy customer, who used it daily to help prevent pregnancy stretch marks.

Scars

Scars are the results of the overproduction of collagen when skin is injured, whether it’s from surgery, burns, cuts or acne. Vitamin E can help drastically improve the texture and tone of scars and the surrounding skin.

"I have been using this on my legs in hopes to lighten scarring from years of trichotillomania," wrote one user. "It has done a good job of lightening the older scars and keeping the skin and current scabs soft."

Another wrote: "I get pretty bad hormonal cystic acne that leaves behind dark scars for months. I've never found a product that made them disappear until this stuff. I used it day and night every day, and it worked wonders on my scars."

Dry skin

Fans of Bio-Oil swear by the multi-use oil for dry skin, too. The formula works as a moisturizer to supplement the skin's natural oils and reduce irritation and inflammation. The result? Softer, smoother skin.

"This stuff is awesome," raved a 5-star reviewer. "I get dry patches on my face in the winter and since using this, no more dry patches! I have pretty sensitive skin, and I can't use most creamy moisturizers because I'll break out, Bio-Oil adds the moisture I need without breaking me out. It also helps to reduce old acne scars and evens out my skin tone. As an added benefit, the smell is light and clean!"

Another, who called it a "magic elixir," wrote: "A must for those with eczema. My 8-month-old has been completely cleared of it except for a few tiny patches. It's kind of a miracle worker. It smells good, a little goes a long way, and on top of helping his eczema, it's cleared up my KP [keratosis pilaris] on my arms and faded stretch marks."

Uneven skin tone

Inconsistent melanin production triggered by everything from sun exposure to hormones shows up on the surface as uneven skin tone. Amazon shoppers swear by Bio-Oil for an even, more radiant complexion.

"I've recently gotten breakouts, dark spots, texture and dry skin like never before," shared one reviewer. "My breakouts are disappearing, my dry spots are going away, and some of my dark spots are lightening. It is seriously amazing. I highly recommend this to anyone having trouble keeping their skin under control. I'm obsessed!"

Another added, "I have very sensitive skin and skin allergies but haven't had a single issue with Bio-Oil. The melasma around my jawline has faded considerably [and] the dry areas are smoothing out. My skin is very soft and smooth."
