Lasers Designed for Acne and Aging Effective for Rosacea
ORLANDO, Fla. — For decades, pulsed dye laser (PDL) has been an established treatment for rosacea, with intense pulsed light (IPL) emerging as a more recent alternative. But new energy-based approaches also appear promising, especially for hard-to-treat disease subtypes. At The American Society for Laser Medicine and Surgery (ASLMS) 2025 Annual Meeting, specialists shared experimental strategies for treating rosacea and other vascular skin conditions, including rare presentations and severe subtypes. Several of the treatment strategies involved energy-based devices designed for other indications. Acne-Targeting Laser for Papulopustular and Phymatous Rosacea Dermatologist Hyemin Pomerantz, MD, who practices in Wellesley, Massachusetts, presented results from an observational study using a 1726 nm laser, which is designed to treat acne by selectively targeting sebaceous glands, in patients with mild to severe papulopustular rosacea. In this disease subtype, papules and pustules occur alongside redness and inflammation. The idea for the study, Pomerantz said at the meeting, came from her observations of treating patients with acne using the device. 'It works well for inflammatory papules in acne vulgaris,' she noted. And in a small, unpublished split-face study using the device in patients with acne, Pomerantz and her colleagues saw that inflammatory symptoms also improved on the untreated side. 'We were wondering if there might be a systemic influence of the device in lowering inflammation,' she said. 'We then wondered if it would help the inflammatory aspect of papulopustular rosacea.' The five patients in Pomerantz's study ranged in age from 31 to 50 years; three were women. Four had failed oral antibiotics or topical therapies, and one responded to these therapies but wanted to avoid medication because she was pregnant. Patients underwent 1-3 laser treatments spaced 1 month apart. While the oldest patient saw less improvement than the rest, all experienced visible improvement, Pomerantz reported. This argument, she said, called for further investigation of the 1726 nm laser as a treatment for rosacea. While some sebaceous gland involvement is thought to occur in all rosacea, phymatous rosacea is characterized by the overgrowth of these glands, often on the nose (rhinophyma). This growth can also affect other areas of the face. Usual treatment involves surgery, which may result in more severe scarring and other adverse effects in patients with disease in areas besides the nose. At the meeting, David Hashemi, MD, who practices dermatology in Neptune, New Jersey and New York City, presented two cases using the 1726 nm laser in two men, aged 62 and 60 years, with severe, disfiguring phymatous rosacea. The first patient underwent electrosurgery on the nose, followed by 1726 nm laser treatment on the cheeks and chin. Similar to what Pomerantz observed in her inflammatory acne pilot study, the patient saw improvement in an untreated area — the forehead. The second patient, treated with the laser only, experienced halted progression and clinical improvement. In an interview, Hashemi said he had also used the device on a patient with the more common erythematotelangiectatic subtype of rosacea, which is characterized by redness and flushing, and the benefit was less pronounced. Still, he noted, papulopustular rosacea 'is almost as common as the redness type. And then when it starts to get into the phymatous category, that's where we see the most significant results' from the 1726 nm laser. Phymatous presentations are rare, Hashemi said, but can be difficult to treat. 'The eye, the chin, the cheeks, the forehead — you don't necessarily want to be doing electrosurgery in those areas.' Commenting on the findings by Hashemi and Pomerantz, dermatologist Paul M. Friedman, MD, who practices in Houston and is a past president of the ASLMS, praised them as an example of 'utilizing existing technology outside of the box to target and go after challenging conditions.' Tightening Laser Shows Surprise Benefit Against Redness A 1550 nm laser with 'focal point' technology, designed to promote skin tightening in all skin types, also works on facial erythema, according to results presented by Dieter Manstein, MD, PhD, of the Cutaneous Biology Research Center at Massachusetts General Hospital in Boston. 'Typically, you wouldn't pick a 1550 nm laser for treatment of vascular lesions,' Manstein said at the meeting. But in a prospective study enrolling 31 patients with facial erythema (ages 22-66 years; 71% women; Fitzpatrick skin types I-IV), Manstein found that erythema was reduced by a mean 30% after an average of four treatments with the device ( P < .05), administered at 4- to 6-week intervals. Blinded evaluations of pre- and posttreatment photos were used to determine treatment effect, and the improvement was sustained at 3-month follow-up. The device used in the study creates a conical shape that allows for less involvement of the epidermis while delivering high energy deeper into the dermal layers. Although the 1550 nm wavelength has no selectivity for blood vessels, as with the PDL, the focal point laser can seal small blood vessels by generating a pattern of coagulation zones within the dermis. In an interview following his presentation, Manstein said his results 'serve as a reminder that for the treatment of abnormal blood vessels, we might want to also consider concepts other than the classic 'selective photothermolysis,' he said, referring to the established laser treatment model using wavelengths that selectively target hemoglobin. 'To use a nonselective laser for treatment of blood vessels is a game changer.' In a separate presentation, Roy Geronemus, MD, of NYU Langone Health, New York City, who also has a private practice in New York City, showed the case of an older adult woman patient with a severe port wine stain he successfully treated using the 1550 nm focal point laser. Port wine stains are a type of vascular lesion that can begin as a birthmark and thicken and redden over time. These, too, are usually treated with PDLs. In an interview, Geronemus said that he has been using the device experimentally for treatment-resistant port wine stains and seeing success. 'We are working right now on a case series, a retrospective analysis of our efforts to improve port wine stains that haven't responded as well as we'd like to laser treatment, and also some of the hypertrophic or thicker stains that are more difficult to treat,' he said. The laser 'is helping a variety of vascular [skin] conditions. This is a sort of an accidental finding,' Geronemus added, noting that his own investigations were inspired by findings from Manstein's group. 'There's a lot to explore there.' PDL: An Option for Refractory Ocular Rosacea Rosacea blepharitis, also known as ocular rosacea, occurs when inflamed facial blood vesselsrelease proinflammatory cytokines that propagate to the eyelids, disrupting the function of the eye's meibomian glands and causing dry eye symptoms. Though cases have been treated successfully with IPL, a team of dermatologists at the Naval Medical Center, San Diego, presented results from a split-face placebo-controlled trial using a 595 nm PDL. They chose this approach, they said, because it had the advantages of a smaller handpiece to maneuver, no need for pretreatment anesthesia, easier cleanup, and possible therapeutic benefits over standard treatment. Monica Borza, DO, presented findings from five patients referred to the hospital's dermatology service from ophthalmology. Four were treated with PDL on one side of the face, including the periocular area, cheek, and forehead, and received sham treatment on the opposite hemiface, while one patient was treated on both sides. Treatment was performed every month for 4 months, and intraocular metal eye shields were used in all patients. Borza reported that the PDL treatment was safe and well tolerated and that all patients had significant improvement on the treated side, according to assessments by ophthalmologists using a validated disease scoring tool. She noted that this was the first time PDL had been investigated in patients with rosacea blepharitis and may offer a more practical option for dermatologists over IPL. Commenting in an interview on the study by Borza and her colleagues, Manstein said he found the results intriguing for a different reason. 'For years, we have treated rosacea with the idea that skin improves only where you directly aim the laser,' he said. 'Here we saw that treating the skin adjacent to the eye reduced an inflammation of the eye. I would like to know whether this represents the kind of anti-inflammatory 'field effect' we are seeing in the other studies.' What the findings from the conference collectively show, Manstein continued, 'is that we still don't know everything about rosacea and that a paradigm change may be underway.' Geronemus disclosed financial relationships (consulting, contract research, and/or speaker fees) with Accure, Allergan, AbbVie, Avava, BellaMia Technologies, Inc., Candela Medical, Cynosure Lutronic, Cytrellis Biosystems, Inc., Galderma, Novoxel, Sofwave Medical, Solta Medical, and the New York Stem Cell Foundation. Friedman disclosed financial relationships with Acclaro, Allergan, Candela Medical, Cytrellis Biosystems, Inc., Merz Aesthetics, R2, and Solta Medical. Manstein is a co-founder of Blossom Innovations, the company that manufactures the AVAVA (1550 nm) device used in his study, and reported relationships with German Medical Engineering, R2, Shiseido, and IPG Photonics. Pomerantz is a consultant for Accure.

Married At First Sight star reveals devastating cryptic pregnancy in heartbreaking admission
Married At First Sight star Laura Vaughan has revealed she suffered a devastating cryptic pregnancy, that she didn't discover until the third trimester. The reality star, 35, who recently announced that she had found love again after her failed union on the show, opened up about the traumatic experience, which happened in 2016. She was forced to undergo a medical abortion after unknowingly putting her foetus at risk of 'extreme harm' and defects with the drug she was taking to treat her acne. Laura told The Sun: 'It was very difficult because I went from not thinking I was pregnant to being seven months pregnant to then having a very prolonged abortion and where I was so far gone. 'Then, when I got home from the procedure, my milk came in, which, as you can imagine, was just really hard to deal with. 'I hunkered down at home for weeks and didn't talk to anyone.' Laura appeared on Married at First Sight in 2023 when she was paired with Arthur Poremba, but their union was not to last after she realised he couldn't give her what she wanted in a marriage. Reflecting on her cryptic pregnancy, Laura said she thought it was 'impossible' when she first discovered that she was pregnant. This shock was only worsened when she was told that she was in the third trimester. While the star had sought treatment for her missing period and stomach cramps, her GP told her it was the result of a 'ruptured cyst' and not a pregnancy. However, she admits she was referred for an additional scan at the time but failed to book it in. Laura said that despite being so far along, she was able to fit into six 6 to 8 dresses, which also left her convinced that her GP's diagnosis was the correct one. She added: 'It was literally the week I decided to test that my stomach popped, and I remember thinking "this isn't right".' The situation went from bad to worse when Laura discovered the effect that her acne drug, Isotretinoin, is responsible for birth defects. Laura speculates that the pregnancy was the result of an expired condom as she remembers using protection. Those taking the acne drug should be advised to use two methods of contraception because of the immense risk to an unborn unborn foetus, according to dermatologists. Laura said that due to the advanced stage of her pregnancy, she was offered a medical abortion and it impacted her 'heavily'. Some of the issues she faced were the pain of the procedure itself, which lasted a week instead of a day and a half, and an alleged lack of support from medical staff, who she claims forgot to feed her on occasion. The star is hoping that by speaking out about her experience, she can dispel some of the shame that exists around planned abortions. Referring to her stint on MAFS, she said she chose not to tell producers about the ordeal but was forced to confront it anyway when discussing future family plans with husband Arthur. Laura, who said she is smitten with her new partner, said they have discussed the possibility of having children and neither of them see it in their future. If you or someone you know has been affected by baby loss, help is available from Tommy's in the UK on 0800 0147 800 or email midwife@ How common are cryptic pregnancies? One in 450 pregnant women in the UK don't know they are going to have a baby until week 20 of their pregnancy (half-way through), and one in 2,500 women are oblivious to the fact until they go into labour. It's a phenomenon known as cryptic pregnancy - also referred to as 'pregnancy denial'. Cryptic pregnancies typically affect either young women, who have never experienced a pregnancy, or women who believe they've gone through the menopause and who choose not to use contraception. Women with erratic menstrual cycles are also more likely to miss signs they are expecting. This is especially true among women with polycystic ovary syndrome (PCOS), where small cysts grow on the ovaries; the hormone imbalance often leads to irregular or non-existent periods. Yet there are some women who will continue to have monthly bleeds throughout their pregnancy. In this case, a scan at the local GP may be the only method of confirmation. Women may simply not expect to find they are pregnant if they are taking the Pill - but then those taking it religiously can still become pregnant. Eight in 100 women can get pregnant while on the Pill - usually not because of problems with the Pill, but with the taker, either because they've missed the Pill, thrown up or had diarrhoea.
