Liquid Microneedling: How Does it Work? | As Seen in Byrdie

Here at Mona Dermatology, we offer microneedling treatments that help stimulate collagen and elastin in the skin and reduce fine lines, wrinkles, and scarring. For those who may prefer an at-home option to maintain and boost your results, liquid microneedling could be a great option. It’s important to note, though, that at-home treatments will not create the same results as professional in-office procedures. Listen to board-certified Dr. Alexandra Bowles explain how these products work and give some helpful recommendations.

What is liquid microneedling?

Liquid microneedling is a non-invasive skin treatment that uses microscopic, naturally derived “needles” suspended in a serum or cream to gently exfoliate and stimulate the skin. These tiny needles, often called spicules, are small enough to be applied topically but still create a mild, temporary sensation that triggers the skin’s natural repair process.

What’s the difference between liquid microneedling products and professional microneedling treatments?

Liquid microneedling products use spicules or similar microscopic structures to create very small, superficial channels in the skin. When massaged in, the spicules prompt cell turnover, boost circulation, and improve absorption of active ingredients. Professional microneedling treatments use a device with fine needles to penetrate deeper into the skin, stimulating more collagen and elastin production. In my experience, at-home liquid versions are gentler, offer more subtle results, and can be used regularly without downtime.

How do the results of these two microneedling methods differ?

Both encourage renewal and collagen production, but traditional microneedling generally produces more dramatic and longer-lasting results because it reaches deeper layers of the skin. Liquid microneedling is less intense, making it safer for at-home use and easier to incorporate into a regular routine. While you may not see the same degree of wrinkle softening or scar improvement, you can still achieve smoother texture, brighter tone, and a refreshed look with consistent use.

Who are liquid microneedling products for? Is there anyone who should avoid them?

Liquid microneedling can be a good choice for people who want to brighten a dull complexion, smooth rough patches, or boost radiance without visiting a clinic. However, it is not suitable for those with very sensitive skin, eczema, rosacea, active acne, or open wounds, as it can cause irritation. I always recommend that anyone who is pregnant, breastfeeding, or being treated for a skin condition check with their dermatologist before trying these products.

What are some of the key ingredients in liquid microneedling products?

The main ingredient is the spicules themselves, which are microscopic needle-like structures often derived from freshwater sponges or marine plants. Many formulas also include brightening agents like vitamin C or niacinamide, and hydrating ingredients like hyaluronic acid. Soothing botanicals like aloe or centella asiatica to help balance stimulation with skin-calming benefits.

How do the spicules work?

Spicules are the microscopic structures that give liquid microneedling its name and effect. They act as both a mechanical exfoliant and a delivery system for active ingredients. When massaged into the skin, they create a mild prickling sensation and lodge temporarily in the upper layers. This prompts gentle exfoliation and encourages better absorption of active ingredients. They are typically derived from freshwater sponges or marine plants and can remain in the skin for 24 to 72 hours before naturally shedding. While they can be very effective, overuse may cause redness or dryness. It’s important to follow product directions and avoid combining with other strong exfoliants on the same day.

Any other recommendations regarding liquid microneedling?

Liquid microneedling can be a valuable addition to a skincare routine, but results are gradual and build over time. For best outcomes, use the product consistently and avoid pairing it with other strong exfoliants on the same day. Be sure to protect your skin daily with sunscreen, as exfoliated skin can be more sensitive to UV exposure. It works best as part of an overall healthy skin regimen that also includes hydration, balanced nutrition, and sun protection.
