Liquid Microneedling:
What Spicules
Actually Do to Your Skin

Liquid microneedling is one of the most requested treatments at Skin & Soul — and also one of the most misunderstood. It's not a relaxing facial. It's not a quick-fix with zero recovery. It's a clinical resurfacing treatment that works from the inside out, and the results reflect that.

Here's a full breakdown of what's actually happening to your skin, who it's right for, what to expect during the process, and how to take care of yourself after so you get the most out of it.

What Is Liquid Microneedling?

Liquid microneedling is an advanced skin resurfacing treatment that uses spicules — microscopic structures derived from marine sea sponges — to create thousands of micro-channels in the skin. These spicules are hollow rods, approximately 100–200 microns in length, with a sharp-edged, porous structure that allows them to penetrate the epidermis when massaged into the skin.

Unlike traditional microneedling, which uses metal needles to puncture the skin mechanically in-office, spicules embed themselves naturally into the epidermis and remain there for up to 24–72 hours. During that window, they act as a transdermal delivery system — continuously stimulating the skin and facilitating deep absorption of active ingredients long after you leave the treatment room.

How Spicules Work

Once embedded in the epidermis, spicules trigger several key regenerative processes simultaneously. This is what makes liquid microneedling a true corrective treatment rather than a surface-level refresh.

• 01
  Collagen induction and fibroblast activation The skin perceives spicules as foreign particles and launches a wound-healing response. This activates fibroblasts — the cells responsible for producing collagen and elastin — leading to firmer, more resilient skin over time.
• 02
  Microcirculation boost and oxygenation Spicules trigger a histamine response that increases blood flow and lymphatic drainage. This delivers more oxygen to skin cells and helps flush out stagnant pigment from deeper layers — particularly beneficial for hyperpigmentation and dull, congested skin.
• 03
  Accelerated cellular turnover As spicules dissolve, they stimulate keratinocyte proliferation — the process of new skin cells moving to the surface. This is what causes the peeling and roughness in the days following treatment, and what produces the brighter, smoother skin that follows.
• 04
  Deep ingredient delivery Spicules themselves contain vitamins, minerals, natural steroids, and antimicrobial peptides. The micro-channels they create also allow topically applied actives to penetrate far deeper than they could through intact skin — dramatically increasing the effectiveness of every ingredient used during treatment.
• 05
  Melanocyte regulation By normalizing melanocyte activity, spicules help correct hyperpigmentation at a cellular level — making this treatment particularly effective for post-inflammatory pigmentation, sun damage, and melasma.

What It Treats

Liquid microneedling addresses a wide range of skin concerns because of how broadly it impacts skin function — not just surface-level texture.

Liquid Microneedling vs Chemical Peels

Clients often ask me how this compares to a chemical peel. Both promote cellular turnover and collagen stimulation — but the mechanism and experience are quite different.

For clients managing pigmentation on melanin-rich skin, or who haven't responded well to acid-based treatments, liquid microneedling is often the smarter path. Some clients benefit from alternating both depending on their skin goals and timing.

What to Expect: The Full Timeline

This is the part I want every client to read before they book. Liquid microneedling is not a lunchtime treatment. There is a real recovery process, and knowing what's coming makes it a much better experience.

• Day 1
  Treatment day

  During the treatment you'll feel a prickly, stinging sensation as spicules penetrate the skin — this is normal and expected. Immediately after, skin may appear red and feel rough, similar to a mild sunburn. Do not cleanse, apply moisturizer, or apply SPF for the first 24 hours. The skin needs to be left fully undisturbed during this initial phase for best results. Book your appointment later in the day if possible to minimize sun exposure on the way home.

• Day 2
  Spicules still active

  After 24 hours, cleanse gently and apply a light moisturizer. Tingling, tightness, and sensitivity are normal — the spicules are still embedded and working. Avoid exercise, saunas, steam rooms, hot yoga, and any heat exposure. Internal heat rising can increase inflammation and risk of PIH. Cold compresses can help if you're uncomfortable.

• Day 3
  Roughness and mild peeling begin

  Mild to moderate flaking, dryness, or rough texture is completely normal at this stage. The spicule sensation may still be present. Continue avoiding heat and exercise. Do not pick, scratch, or manually remove any peeling skin — this is the fastest way to cause PIH or uneven results. Let the skin shed naturally.

• Days 5–7
  Peeling and renewal

  Peeling is normal and may be at its peak or starting to subside. Skin should be looking noticeably brighter and smoother underneath. Keep the routine gentle — no exfoliating acids, retinoids, or active serums for at least 7 days post-treatment. Broad-spectrum SPF 30+ daily is non-negotiable from day 2 onward.

• Week 2+
  Results continue building

  Once peeling has fully subsided, resume your normal skincare routine based on your skin type and concerns. Collagen induction continues working in the background for weeks. Results progressively improve in texture, tone, and clarity. The next session can be booked 10–14 days after peeling has finished.

Who Is Not a Good Candidate

Liquid microneedling is not right for everyone. Please flag any of the following before booking:

Pre-Treatment Prep

For 5–7 days before your appointment, discontinue the following:

• —
  Retinoids and retinol-based products
• —
  Exfoliating acids — AHAs, BHAs, PHAs, and physical scrubs
• —
  Benzoyl peroxide or strong acne treatments
• —
  Heavy, occlusive moisturizers — switch to something lighter in the days before

Clients who prep properly experience less irritation, more even exfoliation, better ingredient absorption, and faster recovery. Skipping this step can result in increased discomfort, uneven peeling, or no peeling at all.

How Often Should You Book?

Each session should be spaced 10–14 days after peeling from the previous one has fully subsided. For active corrective goals — significant pigmentation, texture, or aging concerns — a series of sessions produces the most meaningful results, followed by monthly maintenance. We'll map out the right plan for your skin at your consultation.

Liquid microneedling should not be combined with chemical peels, traditional microneedling, or laser in the same session. Space these treatments at least 3–4 weeks apart.
