Skin Boosters: What Practitioners Need to Know (But Most Aren’t Taught)

 "Skin booster" has become one of the most overused and misunderstood terms in aesthetics. It sounds impressive, but most practitioners haven't been taught the clinical differences between the various products falling under that label, or when and how to use them properly.

This guide breaks down the key distinctions, mechanisms, and treatment logic behind skin boosters so you can prescribe with clarity, not guesswork.

What Actually Counts as a Skin Booster?

In clinical terms, a skin booster is a product designed to improve skin quality, not structure or volume. That means: hydration, density, texture, elasticity, tone, and overall dermal function.

If your product doesn’t reach the dermis or stimulate cellular activity, it may hydrate the surface, but it’s not a true booster.

The 3 Core Categories of Skin Boosters

1. HA-Based Boosters

Example: Profhilo, Jalupro, Seventy Hyal

• Hydrophilic (attracts water) to deeply hydrate and plump
• May provide low-level collagen stimulation via fibroblast activation
• Typically injected in bolus or microdroplet technique 

2. Polynucleotides

Example: Plinest, Newest

• DNA fragments that support cell regeneration and repair
• Anti-inflammatory, ideal for post-inflammatory ageing, scarring, and compromised skin
• Often used in a course for progressive results

3. Exosomes

• Nano-scale vesicles that influence cell signalling
• Stimulate fibroblasts and keratinocytes to promote tissue repair, collagen production, and balanced cell turnover
• Can be delivered via microneedling due to their size and structure

Why Delivery Method Matters

You can have the right molecule, but the wrong method.

• Injectables: Deliver directly into the dermis, making them effective for dense HA gels and certain polynucleotide formulations
• Microneedling: Suitable for nano-structured actives like exosomes and some peptides that can pass through microchannels
• Topicals: Useful for support, but limited penetration. Alone, they are not clinically comparable to injected or needled delivery. 

If you’re calling microneedling with plain HA a "booster treatment," it’s time to revisit your product specs.

Choosing the Right Booster for the Right Indication

The question isn’t "What’s popular?" It’s "What’s clinically appropriate?"

Your decision should be based on:

• Skin condition vs skin type
• The inflammatory state of the skin
• Cellular function and barrier health
• Desired treatment depth, spread, and outcome

Understanding why you’re choosing a molecule is just as important as knowing how to deliver it.

The Knowledge Gap in Training

Too many practitioners are performing skin booster treatments without truly understanding:

• How fibroblast vs keratinocyte stimulation differs
• When barrier dysfunction needs correcting first
• Why delivery methods change the outcome
• What their product is actually doing at the cellular level

These gaps aren’t your fault. Most CPD courses simply don’t teach it. But it’s your responsibility to fill them if you want to work at a clinical standard.

Final Thought

Knowing the difference is what separates a technician from a clinical professional.

If you're offering skin boosters, you should understand them, not just inject them.
