Yes, you can apply the FRESH JUICE Cherry lip balm under lipstick as a softening layer. The sunflower oil in its composition helps smooth the lip surface, which can make lipstick application more even, especially if your lips tend to look flaky or uneven.
However, for matte lipsticks specifically, a glossy balm requires a careful approach. Matte formulas are designed to adhere to a dry surface and provide a long-lasting, non-shiny finish. Applying too much balm, or not allowing it to absorb sufficiently, can create a slick base that prevents the matte color from setting properly, leading to patchy application, reduced longevity, or a shift towards a satin or glossy finish.
For best results with matte lipstick, apply a thin layer of this balm at least 5–10 minutes before your lip color. Gently blot off any excess sheen with a tissue, leaving your lips feeling smooth but not oily. This prepares the canvas without compromising the matte effect. As a general rule, for a truly long-lasting matte look, a dedicated, lightweight lip primer or a tiny amount of a fragrance-free, non-greasy moisturizer might be a more compatible choice.
