Maelys Cosmetics B Flat Cream Review



Stretch marks seem to be an unfair price many people have to pay after certain stages of life, such as transitioning from adolescence to adulthood, working out and building muscles, and having children.

While these marks aren’t harmful in any way, many people consider them to be unsightly and wish to get rid of them. But is that even possible?

According to the American Academy of Dermatology, stretch marks are permanent, but treatment may make them less noticeable. 

One product that’s specifically formulated to help reduce the appearance of stretch marks and promote a firmer-looking belly is B Flat Cream by Maelys Cosmetics. 

B Flat Cream has been called a “tummy tuck in a container” and has earned more than 3,000 5-star reviews. 

So is B Flat Cream really the solution to stretch marks? To answer that question, we’ll have to evaluate the key ingredients in this formula, as well as the research that supports (or doesn’t support) their use for treating stretch marks.

We’ll also share some B Flat Cream reviews so that you can get an idea of what customers really think of this product.

  • Skin type? Anyone with stretch marks
  • Texture? Lightweight and creamy
  • Fragrance? Yes

What Are The Key Ingredients in B Flat Cream?

In order to determine whether or not B Flat Cream really helps with stretch marks, we’ll have to evaluate the key ingredients in this formula. Let’s get started.

Pink Pepperslim

B Flat Cream is said to help reduce the appearance of stretch marks and promote a firmer-looking belly, and one of the main ingredients that provides this benefit is Pink Pepperslim.

Pink Pepperslim is the trade name for an extract from the seeds of Schinus terebinthifolius, also known as the Brazilian pepper tree.

According to the manufacturer, Pink Pepperslim is able to prevent the transformation of small lipid (fat) droplets into larger ones, decrease the cellular production of fat storage, and stimulate microcirculation.

Clinical testing demonstrated that Pink Pepperslim led to a loss of up to 2 cm in both men and women after 28 days of treatment. 

Guaraná for Skin Tightening+

Another key ingredient in B Flat Cream that helps to tighten and smooth skin is Guaraná extract. 

Found in the Amazon, Guaraná is a climbing plant that has five times more caffeine than coffee, and caffeine is well known for its ability to tighten the look of skin. 

As a natural stimulant, caffeine causes vasoconstriction (constriction of the blood vessels) and stimulates blood flow when applied to the skin. Vasoconstriction can tighten and firm the skin due to the removal of excess fluids and possible stimulation of the lymphatic drainage system.

Caffeine also prevents excessive accumulation of fat in cells. According to a publication in the journal Skin Pharmacology and Physiology, caffeine stimulates the degradation of fats during lipolysis through inhibition of the phosphodiesterase activity.

Furthermore, dermatologist Julie Russak, M.D., explains to Women’s Health, “Caffeine dehydrates the fat cells and stimulates circulation, therefore making the skin appear tighter and smoother.”

However, she notes that these effects are temporary and shouldn’t be relied on as long-term solutions.

Shea Butter and Cocoa Seed Butter

If you’ve tried other stretch mark products, you probably know that most of them contain shea butter and cocoa seed butter, and it turns out that B Flat Cream contains these ingredients, too. So how do these two naturally-derived butters help with stretch marks?

Both shea butter and cocoa seed butter are excellent emollients thanks to their rich supply of triglycerides and fatty acids that create a protective layer on the skin in order to lock in moisture. 

In addition, both shea butter and cocoa seed butter contain nutrients that help to heal and regenerate skin.

Shea butter is a natural source of vitamin A, which helps to firm the skin. Cocoa butter contains polyphenols, which have been shown to improve skin health by increasing skin’s elasticity and hydration.

Avocado Fruit Extract

The inclusion of avocado fruit extract in B Flat Cream is another way to support skin healing and prevent the look of stretch marks. 

According to a publication in the journal Phytotherapy Research, unsaponifiables in avocado have been shown to reverse the degenerative skin changes seen with aging by stimulating the synthesis of collagen and elastin fibres, thereby restoring toward normal the regenerative/degenerative equilibrium.

In simpler terms, this means that avocado unsaponifiables increase production of collagen and elastin, the two most important proteins for maintaining firm and elastic skin. 

How to Use B Flat Cream?

Apply a generous layer of B Flat Cream onto the belly area. Massage the cream into the skin in circular motions until it is fully absorbed. You will start to feel a warming sensation. Do not rinse off. Use daily for best results.

Where to Buy B Flat Cream?

B Flat Cream and other Maelys Cosmetics products are sold on the brand’s website (, as well as several third party online retailers such as Ulta and Amazon. 

How Much is B Flat Cream?

B Flat Cream costs $49 USD for 3.38 fl oz on the brand’s website.

Our Verdict

Overall, we think that B Flat Cream is formulated well and it should help to reduce the appearance of stretch marks so they are less noticeable, but don’t expect it to completely eliminate all stretch marks.
