Our formulas go through rigorous clinical trials conducted on panels of real women. The trial found that B-FLAT is:

• Clinically proven to promote smoother-looking belly skin.
• Clinically proven to decrease the look of belly skin roughness.

*Based on a 56-day clinical trial with 28 participants.

1. Apply a generous layer to stretch marks and loose skin in the belly area.
2. Massage into the skin in circular motions until fully absorbed. 
3. You may start to feel a warming sensation, that’s totally normal! If you’re not into the tingle, we recommend waiting at least 20 minutes after a shower before applying.
4. Use twice a day for best results.

• Formulated without: Parabens, SLS, and Phthalates.
• Brazilian Peppertree: A powerful bioactive derived through supercritical CO₂ extraction that helps to reduce the appearance of visible puffiness and unevenness. Skin looks smoother, more toned, and more contoured with continued use.
• Bentonite Firming Complex: A combination of unroasted Shea Butter Extract, Avocado Seed Extract, and Bentonite Clay - each processed using methods that preserve their most active properties. Unroasted Shea Butter Extract supports the look of contoured skin, Avocado Seed Extract visibly supports the appearance of firmness, & Bentonite Clay acts as a progressive-release delivery system generally shown to help visibly reduce the appearance of stretch marks over time. Together, they address the look of the belly's contour, firmness, and stretch marks simultaneously.

Full list of ingredients.

• Why does belly skin need its own formula - can't I use a regular firming cream? Belly skin experiences a specific combination of visible challenges - repeated expansion and contraction, stretch marks, and a particular kind of visible softening. B-FLAT's formula was built around belly skin specifically, including a progressive-release stretch mark system that requires the right delivery mechanism to work. The visible results reflect that specialization.
• What makes the Bentonite Firming Complex different from standard shea or clay? Each ingredient is specifically processed to preserve its most active properties. The Shea Butter Extract is unroasted - skipping the processing step that destroys its most visibly active compounds. The Avocado Seed Extract is specifically rich in visible firming compounds. The Bentonite Clay provides a progressive-release delivery system and naturally occurring silanols, shown to help visibly reduce the appearance of stretch marks. It's the combination and formulation together that delivers results no single ingredient could achieve.
• What's the warming sensation?The warming sensation is caused by VBE (Vanillyl Butyl Ether), a unique ingredient that provides an immediate and temporary warming sensation to help the skin better receive powerful ingredients in the formula. This warming varies from body to body based on skin sensitivity, and there's a chance you may not feel it at all. Either way is totally normal. If you're not a fan of the sensation, we recommend waiting 20 minutes after a shower before using the product, as the hot water makes you more susceptible to the warming. Once you're done applying the product, be sure to wash your hands with soap and cold water.
• Can B-FLAT be used on areas beyond the belly? Yes. People may find it equally effective on the hips, and anywhere stretch marks or visible softening are a concern. The Bentonite Firming Complex is belly-first, not belly-only. If it works for the most challenging zone, it works everywhere.
• How does B-FLAT fit into a full MAËLYS routine? B-FLAT is your dedicated belly step. Apply GET-UP Daily Toning Body Milk all over first as your morning foundation, then apply B-FLAT to the belly for concentrated firming and stretch mark support & finish with GET-SPRUNG Stretch Mark Oil to lock everything in.
• Can MAËLYS products be used during pregnancy or breastfeeding? If you are pregnant or breastfeeding and would like to use it, we recommend consulting with your physician beforehand. Don't forget, B-FLAT has a warming sensation, so if you do decide to try it, we recommend waiting until it has fully absorbed and the tingle has gone before nursing or touching your baby to your skin.

MAËLYS Biology-First Skin Response Science™ is an approach grounded in nature-derived bioactives, extracted through advanced, high-purity, and biotech-enabled methods, and clinically shown to influence the body-specific skin pathways that govern body skin behavior.

We know that the skin on the body isn’t static - it adapts based on how your skin reacts: daily exposure to the environment, movement, hormones, gravity, and time trains skin to respond in patterns that result in skin changes such as sagging, crepiness, uneven tone, and loss of firmness. So instead of working against your skin, our clinically tested body care is designed to work with it, and support how skin responds to real life.

Every MAËLYS fragrance is carefully composed with a specific experience in mind. From the top notes, through the heart, to the base, each layer is designed to communicate efficacy, inspire confidence, and transform your routine into a moment you truly look forward to.

A fruity floral that wears easily.

Top notes: Apple, Orange, Mixed Berries, Tropical Fruit.
