Rockstar by sosu x my naked bar
A truly sustainable deodorant with Rock Star.
Meet Rockstar—a truly natural crystal deodorant for those who want long-lasting odour protection without compromising on skin health or sustainability.
Unlike conventional deodorants that rely on aluminium chlorohydrate, alcohol, artificial fragrances or pore-clogging ingredients, Rockstar is made from 100% natural mineral salt crystal (Potassium Alum). It works by creating an invisible mineral layer on the skin that helps inhibit the growth of odour-causing bacteria, so you stay fresh throughout the day while allowing your body to perspire naturally.

Frequently Asked Questions
Rockstar is a deodorant. It helps manage body odour, but it does not stop you from sweating.
Sweat itself is not the real villain. Body odour usually happens when bacteria on the skin break down sweat and create odour.
If you want to block sweat or reduce wetness, this may not be the right product for you.
Yes. Potassium alum is a type of aluminium salt. It is different from common antiperspirant actives such as aluminium chlorohydrate or aluminium zirconium salts, which are used to reduce sweating by blocking sweat ducts.
No added scent. It will not make you smell like flowers, powder or perfume. It is made for people who prefer a clean, neutral deodorant routine.
It should not leave the same creamy or oily residue as many stick deodorants. Let your skin dry before dressing to reduce transfer.
Yes. Besides underarms, Rockstar can be used on feet or other sweaty areas where odour tends to build up.
Potassium alum has also traditionally been used as an after-shave block because it is astringent and can help calm the feel of freshly shaved skin. Some people also dab it lightly on occasional spots or blemish-prone areas to help keep the area feeling clean and dry.
Use it sparingly, avoid broken or irritated skin, and stop if your skin feels tight, stingy or uncomfortable.
Try not to. Rockstar is a crystal, so it can chip, crack or break if dropped, and broken pieces may have sharp edges.
If it breaks, do not throw the pieces away. Smooth pieces can still be used carefully as deodorant, on feet, or as an after-shave block. Smaller or sharper pieces can be dissolved in warm water and used as a simple deodorising rinse for areas like feet.
Store any broken pieces safely and keep them away from children and pets.
With proper care, one crystal can last months and potentially years. Keep it dry between uses and do not drop it.
Store it on a dry soap dish, tray or its paper wrapper on a flat surface. Do not leave it sitting in a puddle, or it may dissolve faster.
