The Technology Behind Secret Slim Compression Shorts

With the combination of; seaweed-based 3D ceramic fiber and cosmetic qualities of microcapsules, Secret Slim Compression Shorts help to reduce inches around the stomach and hips, ensuring an anti-cellulite effect. 

The active cosmetic ingredient (microcapsules) is released directly by the movement of the body while the ceramic fiber helps to reduce fatty cells. Paired with bio-ceramic crystals all encompassed in a unique 3D knit fabric, our compression shorts give you a micro-massage effect improving blood and lymphatic circulation on the targeted areas over time, resulting in reduced cellulite and improved elasticity.

Feel TheBlackPurple difference.

    I have been using the Mass & Slim for aImost a week now and I am loving them!! I can wear them under anything. I love the way my outfits look immediately and I am already seeing a difference with smoother skin and I think I am losing inches!! I know my weight gain didn’t happen overnight and I am making all kinds of healthy changes in my life to be a better version of myself!

    I look good! I bought my first Mass & Slim shorts from TheBlackPurple.


    I am very happy with the quality of the shorts, even happier with how I look after I wear them.
