1. Start with B-FLAT. Apply a generous layer to stretch marks and loose skin in the belly area, then massage in circular motions until fully absorbed. You may start to feel a warming sensation - that’s totally normal. If you’re not into the tingle, wait at least 20 minutes after a shower before applying.
2. Follow with GET-SPRUNG. Pump the product into the palm of your hand and apply it directly to stretch marks in the target area. Massage in circular motions until fully absorbed.
3. Use both products twice a day for best results.

• Formulated without: Parabens, SLS, and Phthalates.

• Is this duo only for people who already have stretch marks? No. This two-step routine is for anyone looking to visibly improve the appearance of stretch marks and support smoother, firmer-looking belly skin. Whether these visible changes are connected to pregnancy, weight changes, growth, or other body transitions, B-FLAT and GET-SPRUNG work together to support how belly skin looks and feels.
• When should I start using this routine? You can incorporate these products whenever you begin noticing visible changes in your belly skin, such as stretch marks, rough-looking texture, or a loss of firmness.
• Why does this routine combine a cream and an oil? Each formula has a different role in the routine. B-FLAT is a targeted belly cream that helps improve the appearance of firmness and smoothness while helping to visibly reduce the appearance of stretch marks. GET-SPRUNG is applied directly to stretch marks to help reduce their appearance, smooth the look of skin, and increase the look of skin firmness. Together, the two textures create a complete cream-to-oil routine for the belly area.
• 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.

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.
