Hydrosols

Hydrosols are aromatic waters obtained through steam distillation of plants: a noble by-product that retains the water-soluble molecules of the plants and a delicate portion of essential oils. Naturally versatile, they are used in facial, body, and hair care, as well as an ingredient in DIY cosmetic preparations. With 131 selected references, this collection gathers hydrosols of certified plant origin, pure or ready to use, suitable for every type of need.

How to choose the right hydrosol for your needs

The first criterion for selection is the plant of origin: each hydrosol has a distinct aromatic profile and chemical composition. Chamomile hydrosol, for example, is traditionally associated with formulations for sensitive skin, while lavender hydrosol is among the most versatile. Always check that the product label includes the complete botanical name, the extraction method, and the absence of added preservatives, elements that ensure quality and purity. Prefer products packaged in dark glass or barrier materials: hydrosol, being water-based, is more vulnerable to contamination compared to oils.

A common mistake is to confuse hydrosol with scented floral water, which often contains preservatives, alcohol, or synthetic fragrances. Read the ingredient list: a pure hydrosol should have as its only component aqua followed by the botanical name. Also evaluate the concentration: some products are already ready to use, while others may need to be diluted before application. If you use it in DIY cosmetics, accurately calculate the percentages in the formulation and store the product in the refrigerator once opened.

Frequently Asked Questions

What is the difference between hydrosol and essential oil?

Essential oil is the concentrated lipophilic fraction extracted from the plant, while hydrosol is the aqueous phase that separates during distillation. Hydrosol contains aromatic molecules in much lower quantities and is generally usable directly on the skin without dilution, unlike essential oils which almost always require a carrier.

Do hydrosols have an expiration date?

Yes. Being water-based, hydrosols are subject to microbial contamination. Respect the expiration date indicated on the label and, once opened, store them in the refrigerator, preferably consuming them within the time indicated by the manufacturer.

Can I use a hydrosol on my face every day?

In general, pure hydrosols are among the least aggressive cosmetic products. However, as with any cosmetic, it is advisable to perform a patch test before prolonged use and consult a pharmacist or dermatologist in case of reactive skin or specific conditions.
