With the rise of eco-friendly and zero-waste movements, solid cosmetics are becoming increasingly important in our skincare routines. Whether it's shampoos, soaps, or even deodorants, these solid versions offer an alternative to traditional liquid products. But why should they replace your bottles and tubes?
Here's an overview of the main advantages of solid cosmetics over liquid cosmetics.
1. Reduction of plastic waste
One of the biggest advantages of solid cosmetics is their lack of plastic packaging. In fact, plastic bottles often end up in the trash once they're used up.
Solid cosmetics:
- Less plastic packaging! They are generally sold in cardboard, recyclable paper, or even bulk packaging.
- You are directly contributing to reducing plastic pollution, one of the biggest ecological challenges today.
Liquid cosmetics:
- Plastic bottles are ubiquitous, and even when they are recycled, their environmental footprint remains significant.
2. A more economical product
Although some solid cosmetics may seem more expensive to purchase, their shelf life is often much longer than that of liquid products.
Solid cosmetics:
- They are highly concentrated in active ingredients, so you use less product per use. For example, a solid shampoo can last up to three times longer than a bottle of liquid shampoo.
- You save money in the long run because you buy your products less often.
Liquid cosmetics:
- Liquid products are diluted with water, making them bulkier and less durable.
3. A practical format for travel
Traveling with liquid cosmetics can be a hassle due to restrictions on liquids on airplanes. Plus, they take up space and can burst open in your bags and luggage.
Solid cosmetics:
- They are compact and lightweight, making them ideal for travel.
- No worries about regulations regarding solids on airplanes, you can take them in your hand luggage or cabin baggage without any problem.
Liquid cosmetics:
- Often bulky and subject to 100ml limits in airplane cabins, they sometimes require travel bottles.
- Can sometimes open in your bag.
4. More natural and skin-friendly ingredients
Solid cosmetics, particularly those from brands committed to an ecological approach, are often formulated with natural ingredients and without additives or preservatives.
Solid cosmetics:
- They are generally preservative-free, as the absence of water in their composition limits the development of bacteria.
- They are often made with organic and environmentally friendly ingredients, such as vegetable oils, natural butters, and essential oils.
Liquid cosmetics:
- Many liquid products contain preservatives, sulfates, silicones, or parabens, substances that can be potentially irritating to some sensitive skin.
5. Save space in the bathroom
With bottles and tubes piling up in our bathrooms, it's sometimes difficult to find space for all the products.
Solid cosmetics:
- They are small, compact, and fit easily into a soap dish or soap box.
- They contribute to a more minimalist and refined bathroom, reducing visual and material clutter.
Liquid cosmetics:
- Bottles and flasks take up space and quickly accumulate, which can make your space feel cluttered.

Switching to solid cosmetics means opting for more responsible consumption, both economical and ecological. These products last longer, generate less waste, are easy to transport, and are generally better for your skin. They fit perfectly into a minimalist routine, while offering the same (or even better) results as their liquid counterparts.
So, why wait to make the switch? Try solid cosmetics and do a simple but powerful thing for the planet while taking care of yourself!
