What Is a Hydrosol? How to Use Floral Water in Skincare

Decades ago, I fell down a research rabbit hole about alchemy and distillation while building a brand called Backyard Botanicals. My vision was obsessive: grow everything myself, distill every essential oil and hydrosol on my own land from plants I grew. What I found changed how I think about skincare forever — because I discovered something the industry was underutilizing and even throwing away. 

That overlooked byproduct was hydrosol. 

Most people are splashing plain water or alcohol-heavy toners on their faces every day, not realizing they could be using living plant water packed with botanical benefits instead. 

Here is what you will learn: what a hydrosol is, how it is made, how it differs from floral water and essential oils, which skin types benefit most, how to use it step by step, and how to store it properly…. Herrroo. 

What Is a Hydrosol?

A hydrosol is the water-based condensate produced during steam or hydro-distillation of plant material. It contains water-soluble plant compounds. Ie: micro-droplets of essential oil and the botanical's full aromatic signature suspended in water.

Here is how the process works. Raw botanicals go into a copper still (aka an alambique in Spanish). Heat causes the plant compounds to separate through condensation, producing two distinct products from one distillation: the essential oil and the hydrosol. Same plant, different products. 

Here's what still frustrates me: in many operations, people discard the hydrosol. Eeeekk waste. In some cases, people treat it as a week-old leftover. The Latina in me wants to honor the fact that the whole plant deserves to be used and adored. The hydrosol isn't a lesser product, folks. It is different and, for skincare, often more appropriate for those with sensitive skin or you practive skin flooding. 

What Is the Difference Between a Hydrosol and Floral Water?

A true hydrosol is produced exclusively through steam or water distillation and contains the full spectrum of water-soluble plant actives. "Floral water" is often a marketing label that may describe either a genuine hydrosol or a synthetic imitation — and unfortunately you cannot tell which just by looking at the packaging. 

The two most common counterfeits on the market are:

1. Diluted essential oils sold and labeled as hydrosols

2. Infused flower waters made by soaking plants in water

Neither is a true hydrosol. 

A real hydrosol requires hand-picked herbs, significant volumes of water, a copper still, and patience. It is a labor-intensive process that you can't replicate by dropping essential oil into a bottle of water.

What Does a Hydrosol Do for Your Skin?

Hydrosols hydrate without stripping the skin's natural oils, calm inflammation, balance the skin's microbiome, and deliver water-soluble plant actives directly to the skin—without the volatile organic compounds that can make essential oils irritating. Ie: this is great for sensitivities. 

Essential oils are concentrated. They can be astringent and sensitizing even when they come from organic botanicals. Hydrosols offer the same botanical benefits without that harshness, making them suitable for daily use on even the most reactive skin. 

My cousin Antonia has very sensitive skin and cannot tolerate many of my products because I do add essential oils to most formulations. Introducing her to hydrosols — plant water instead of complicated formulas — has helped to keep her skin clear, refreshed, and calm. 

According to the National Center for Complementary and Integrative Health, plant-based compounds can meaningfully affect skin health when properly formulated—which is exactly why production method and sourcing matter so deeply to me. Caring for plants is a religion in my corner of the internet. 

How to Use Hydrosol in Your Skincare Routine

The biggest mistake I see is skipping hydrosols entirely — jumping straight from cleanser to serum and missing the hydration and botanical-delivery window that a hydrosol mist creates between those steps. 

Another friend thought she couldn't use my oil-based products, like the bee venom serum, because they'd leave her feeling like a greased monkey. BUT then I told her you can layer it with hydrosol to customize the water you add to your routine, instead of inviting a complicated preservation system to the party.  

Morning: Skip cleanser if you cleansed thoroughly the night before. Instead, mist hydrosol directly onto your skin as a plant-powered refresh. It primes the skin for serums and moisturizer without disrupting your microbiome. 

Evening: After cleansing, apply hydrosol while skin is still slightly damp. It acts as a bridge between cleansing and moisturizing, locking in moisture before you layer heavier products on top.

Seasonal adjustment: I use hydrosol to emulsify a facial balm into a custom moisturizer and adjust the ratio by season. In summer, more hydrosol than balm — lighter, more hydrating. In winter, more balm and less hydrosol to compensate for dryness. A simple, flexible system that adapts your routine without a full product overhaul every few months.

Which Hydrosol Is Best for Your Skin Type?

Oily, acne-prone, or congested skin: Look for hydrosols with clarifying and antibacterial properties. Colloidal silver is a useful addition — it minimizes bacterial growth without aggressively stripping the skin.

Dry, dull, or aging skin: Frankincense and neroli are my go-to botanicals. Frankincense purifies, minimizes pores, and supports skin elasticity. Neroli adds brightness and lifts dull skin without irritating it.

Microbiome support: Some hydrosol formulations now include probiotics — specifically lactobacillus — to feed and balance the skin's microbiome. This is the opposite of what alcohol-based toners do. A microbiome mist combining frankincense, neroli, and lactobacillus addresses aging, brightening, and microbiome support all in one.

3 Common Mistakes With Hydrosols

Mistake 1 — Skipping the step entirely. Jumping from cleanser directly to serum or moisturizer is the most common error. The hydrosol step delivers botanical actives and helps everything that follows absorb more effectively. We need to water our skin… so it may as well be copper-distilled and organic, you feel me?  

Mistake 2 — Buying a fake. If the ingredient list shows "water" and "fragrance" rather than a named plant distillate, it is not a true hydrosol. Look for labels that specify the botanical source and confirm steam distillation as the production method. A genuine hydrosol's ingredient list should be short and to the point. 

Mistake 3 — Storing it incorrectly. Leaving your hydrosol on a sunny bathroom shelf degrades the plant actives quickly. Hydrosols are raw, living plant waters — treat them like fresh produce. Keep them away from direct sunlight and store them in the refrigerator for maximum potency.

How to Store a Hydrosol

Refrigeration is not always mandatory, but it is strongly recommended. Cold storage slows oxidation, preserves water-soluble plant actives, and significantly extends shelf life.

Heat and sunlight are the enemy. Once a botanical is distilled, the clock starts on its potency—just like with any fresh plant material.

There is also a practical bonus: a chilled hydrosol mist is especially effective in winter. Most people are drier than they think in colder months, and a cold spritz delivers instant hydration and reduces puffiness. When something feels good to use, you use it consistently. Hydrosols are no exception. 

How to Spot a High-Quality Hydrosol

Three things tell you almost everything:

1. Production method. Look for "steam distilled" or "hydro-distilled" on the label. If the method is not listed, that absence is itself a signal.

2. Sourcing and traceability. Premium hydrosols come from ethically sourced, hand-picked botanicals — ideally organic. For example, our partner distills our hydrosols in a copper alambique still using botanicals from family farms. 

3. Ingredient simplicity. A genuine hydrosol's ingredient list should be short: the botanical distillate and perhaps a simple preservation system. Alcohol, synthetic fragrance, or a long list of additives signals a diluted or imitation product. The U.S. Food and Drug Administration's cosmetic labeling guidance requires ingredients to be listed in descending order of concentration — use that to your advantage.

The Takeaway

Hydrosols are the overlooked byproduct of distillation. They offer botanical benefits without the irritation risk of essential oils and belong in virtually every skincare routine, regardless of skin type.

Two things you can do starting today: store your hydrosol in the refrigerator and use it either as a morning face wash or as a dedicated toner step between cleansing and moisturizing. I like to use it when I'm drinking my coffee, nothing like a cold burst of hydrosol to wake you up in the morning.
