How to Use the Ultimate Hydration Kit — Your 3-Step Routine Guide

The Ultimate Hydration Kit is a 60-second, 3-step routine — Balance, Pure Hyaluronic Serum and Hydrate — that restores hydration, softness and glow. Here's how to use it, morning and evening, with pro tips and FAQs.

How to Use the Ultimate Hydration Kit — Your 3-Step Routine Guide

The Pestle & Mortar Ultimate Hydration Kit is a 60-second, 3-step routine that restores hydration, softness and glow to tight, dull or dehydrated skin. Balance, Pure Hyaluronic Serum and Hydrate — prep, flood, seal. Used consistently morning and evening, most people notice visibly softer, plumper skin within the first week.

What's Inside Your Kit

Your Ultimate Hydration Kit contains three products, each with a specific job in the routine:

Balance Fine Misting Facial Spritz (30ml) — An Irish deep-sea magnesium facial mist that balances skin's pH and prepares it to absorb everything you layer on top. Think of it as the foundation of the routine.

Pure Hyaluronic Serum (15ml) — A multi-molecular weight hyaluronic acid serum that draws and holds moisture at multiple skin depths. This is the hydration engine.

Hydrate Lightweight Moisturiser (30ml) — A weightless moisturiser with squalane, peptides and jojoba oil that seals in hydration and protects the skin barrier all day.

Your 3-Step Routine (60 Seconds, Twice Daily)

This routine works morning and evening. The order matters — each step builds on the last.

Step 1: Spritz Balance

Hold Balance 15–20cm from your face. Close your eyes and mist 2–3 pumps evenly across your skin. Balance delivers Irish deep-sea magnesium directly to the skin's surface, resetting your skin's pH and prepping it to absorb everything that follows.

Pro tip: Don't wipe or pat after spraying. Leave the mist sitting on the skin — you need that dampness for Step 2.

Step 2: Apply Pure Hyaluronic Serum

While your skin is still damp from Balance, place 1–2 drops of Pure Hyaluronic Serum onto your fingertips. Press gently into your cheeks, forehead, chin and neck. Don't rub — press and smooth. Pure HA contains multi-molecular weight hyaluronic acid, which means it hydrates at multiple skin depths.

Pro tip: Always apply hyaluronic acid to damp skin. On dry skin, HA can actually pull moisture out. The Balance spritz in Step 1 creates the perfect damp base.

Step 3: Seal with Hydrate

Take a pea-sized amount of Hydrate and warm it between your fingertips. Press and smooth over your face and neck in upward motions. Hydrate locks in all the moisture from Steps 1 and 2 using squalane, peptides and jojoba oil.

Pro tip: In the morning, follow Hydrate with SPF. At night, Hydrate is your final step.

Erase and Renew

Morning vs. Evening: Any Difference?

The 3-step routine is exactly the same morning and evening. The only difference is what comes before and after.

Morning: Cleanse → Balance → Pure HA → Hydrate → SPF. The routine takes 60 seconds. Your skin is prepped, hydrated and protected for the day.

Evening: Double cleanse if you've worn makeup → Balance → Pure HA → Hydrate. That's it. No complex layering, no 10-step programme. Three products, clean skin, done.

Ready to Level Up? What to Add Next

Your kit gives you the core hydration routine. Once you've been using it for 2–3 weeks and your skin has settled in, here are the products that complement it best:

Erase Balm Cleanser — The cleanse-before-the-routine. Removes makeup, sunscreen and daily buildup without stripping your skin.

Renew — A gentle resurfacing treatment to use a few nights a week. It lifts dull surface cells so the Pure HA and Hydrate sink in even better.


Frequently Asked Questions

Can I use the Ultimate Hydration Kit on sensitive skin?
Yes. All three products are fragrance-free, vegan, and dermatologically tested. No essential oils, no synthetic fragrance, no harsh actives. Suitable for all skin types including sensitive skin.

Do I use the kit morning, evening, or both?
Both. The 3-step routine works morning and evening. In the morning, follow with SPF after Hydrate. In the evening, use after cleansing as your final three steps before bed.

Why do I need to apply Pure HA to damp skin?
Hyaluronic acid is a humectant — it draws moisture into the skin. Applied to damp skin (after Balance), it pulls that surface moisture deep into the skin layers. Applied to dry skin, it can draw moisture out.

How long will the kit last?
Used twice daily, the Ultimate Hydration Kit lasts approximately 4 weeks — a full month to experience the results before committing to full-size products.

What results should I expect and when?
Softer, more comfortable skin within the first 2–3 applications. By day 7, skin feels plumper. By week 3–4, improved texture, reduced tightness, and a visible glow.
