🔬 CLINICAL PROTOCOL
If you work in professional aesthetics, acne-prone skin is part of your everyday routine. We apply protocols, combine specific cosmetics and, increasingly, incorporate technology such as the blue laser in the treatment room.
And when you understand how the milesman Blauman laser acts on acne-prone skin, the way you work changes. You fine-tune your protocols better, you know what to expect in the days that follow, you convey greater confidence to your client and you work with far more judgement.
In this article we are going to look, step by step, at what happens in acne-prone skin before, during and after treatment with the Blauman blue laser, based on real clinical evidence.
8 sections
- 1. What happens in the skin before treatment
- 2. Porphyrins: the target of the blue laser
- 3. How Blauman acts in the treatment room (step by step)
- 4. The hours and days that follow
- 5. Clinical evidence · studies
- 6. Conclusions and the value of the treatment
- 7. Treatment-room protocol: hygiene + laser
- 8. Frequently asked questions (FAQ)
1. What happens in acne-prone skin before treatment
In acne-prone skin, a fairly well-known sequence tends to repeat itself in the treatment room:
- Increased sebum – follicular hyperseborrhoea
- Cell build-up inside the follicle
- Difficulty draining and microcomedones
- Proliferation of Cutibacterium acnes
This bacterium produces porphyrins, natural compounds that absorb blue light very efficiently.
👉 This detail is the starting point of the entire blue laser treatment.
2. The role of porphyrins: the “target” of the blue laser
The porphyrins produced by Cutibacterium acnes accumulate in the inflamed follicle, becoming the perfect target for the blue laser.
From the laser’s point of view, this is very important because:
- ✅ they are localised
- ✅ they absorb blue light at 450 nm
- ✅ they allow a selective, precise action
Put simply: the blue laser acts where the skin needs it, without affecting the surrounding tissue.
3. How the Blauman blue laser acts in the treatment room (step by step)
Blauman by milesman makes it possible to work on acne-prone skin in an orderly way thanks to the combination of two spot sizes within a single protocol.
·
You act with precision
·
You rebalance the skin again
STEP 1 Global preparation pass (1 cm² spot)
- Act uniformly across the skin surface
- Reduce the surface bacterial load
- Prepare the skin for more localised work
STEP 2 Focal work on active lesions (0.3 mm² spot)
- The energy is concentrated on a very precise point
- Action is taken only where there is visible activity
- There is no bleeding or extended thermal damage
Sensation experienced by the client: mild and well tolerated
STEP 3 Global closing pass (1 cm² spot)
- The porphyrins absorb blue light at 450 nm
- That absorption generates singlet oxygen, an active form of oxygen
- This active oxygen acts on the bacteria inside the follicle
Put simply: blue light activates the oxygen so that it acts precisely where the bacteria are, without damaging healthy tissue.
This final step also: makes the skin’s response more uniform, reinforces the soothing effect and leaves the skin more balanced after the session.
4. What happens in the skin in the hours and days that follow
5. Clinical evidence for the Blauman blue laser: what the studies show
The use of the Blauman blue laser on acne-prone skin is not based on experience alone, but on clinical studies carried out specifically with this technology and this wavelength.
Conclusion: milesman Blauman is effective, safe and well accepted for mild and moderate acne.
6. Clinical conclusions and the value of the treatment
The clinical and histological study “Treatment of inflammatory acne with a high-power diode laser (milesman Blauman®)”, by Dr Mario A. Trelles, shows that milesman Blauman is effective, safe and well tolerated on papules and pustules.
📊 Result in a single session – Trelles study
| Parameter evaluated | Result with milesman Blauman |
|---|---|
| Type of study | Clinical, prospective, blind evaluation |
| Patients | 10 patients (97 lesions treated) |
| Sessions | 1 single session |
| Reduction in lesions | 64% in 3 weeks (p = 0.0051) |
| Skin repair | Rapid and complete (epidermis and dermis) |
| Scarring | None observed |
| Pain | Mild–moderate (mean 3.5/10) |
| Safety | No relevant complications |
| Patient satisfaction | High (mean 8.4/10) |
| Therapist satisfaction | Very high (mean 9/10) |
7. Treatment-room protocol: facial hygiene and blue laser
- Professional facial hygiene tailored to the condition of the skin
- Preparation: clean, dry skin
- Global pass with the blue laser (1 cm² spot)
- Focal and perilesional work (0.3 mm² spot)
- Final closing pass (1 cm² spot)
- Soothing post-treatment cosmetics
- Session planning with maintenance according to progress
8. Frequently asked questions from professionals
The Blauman blue laser integrates very well into complete treatment-room protocols, especially with:
- Specific cosmetic treatments
- Devices used in facial hygiene
- Radiofrequency, to support tissue regeneration processes
⚡ Technology matters.
Knowledge is what makes the difference.
