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?

What are the Best Skin Care Products of 2023?

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
  • Cruelty-free? Yes
  • Cost? $49 USD for 3.38 fl oz

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?

How Much is B Flat Cream?

B Flat Cream Reviews

B Flat Cream reviews on the brand’s website are overall very positive, with the product receiving an average rating of 4.7 out of 5 stars after more than 4,500 customer reviews. 

There are many 5-star reviews for B Flat Cream from customers who were thrilled to see results from this product, such as a reduction in the appearance of their stretch marks and smoother skin texture. 

For example, one review says, “So it has been a month since I started using B-Flat & I just started my second bottle. AND today I had to do a double take! My stretch marks look so much better! I’ve been applying it twice a day after I shower and honestly I enjoy the burning sensation. It lets me know it’s actually working and it has been!”

And another 5-star review says, “I love this product! Highly recommend it! I had 2 babies back to back 14 months apart and with my son I got really bad stretch marks on my hips and tummy. I have a lot of loose skin in my tummy area. I’ve been using it for 1 week and I can already see the difference!”

There’s hardly any negative reviews for the B Flat Cream, but those that we did read were from customers who were disappointed that they didn’t see the results they were hoping for. 

For example, one review says, “I’ve been using twice a day for over a month and I see no difference.”

Other 1-star B Flat Cream reviews mention that the burning sensation was quite uncomfortable, as one reviewer shares, ”Be aware that the ‘warming sensation’ they mention can be pretty extreme. It was so uncomfortable for almost an hour after every application and felt like my skin was burning! I’ve persevered but so far haven’t noticed any changes.”

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. 


  • Formula contains beneficial key ingredients (Pink Pepperslim, guarana extract, shea butter, cocoa butter, avocado extract)
  • Thousands of 5-star B Flat Cream reviews
  • Maelys Cosmetics is cruelty free


  • B Flat Cream contains fragrance, which may lead to skin sensitivity
  • Some people find the warming sensation to be very uncomfortable
