Facial rejuvenation via the sequential combined use of multiple laser modalities: Safety and efficacy

A Novel Macrophage-Activating Gel Improves Healing and Skin Quality After CO2 Laser Resurfacing of the Chest

BACKGROUND

After laser resurfacing, it is imperative that an appropriate postoperative regimen is followed for optimal wound healing. There is currently no consensus about which agents should be used.

OBJECTIVE

To evaluate the safety and efficacy of a novel macrophage-activating gel in a Phase 2B trial to be used after fractionated ablative laser resurfacing of the chest.

MATERIALS AND METHODS

Forty-two adults who received fractionated CO2 laser resurfacing of the chest were randomized (active or placebo) for 5 consecutive days after procedure. Skin quality at baseline and follow-up was assessed by a blinded evaluator using the Fitzpatrick-Goldman Wrinkle Scale. Subject satisfaction with skin healing and quality was also assessed.

RESULTS

At 28 days according to the Fitzpatrick-Goldman Wrinkle Scale, 85% of subjects achieved an improvement of at least 33% for the active group versus 50% in the placebo group (absolute difference 35%; p = .04). Similarly, 75% of subjects achieved an improvement score of at least 33% in elastosis in the active group versus 35% in the placebo group at 28 days (40% absolute difference; p = .011).

CONCLUSION

This study confirms the potent effects of the novel macrophage-activating gel for optimization of skin healing and quality after laser resurfacing of the chest.

[Pre- and post-interventional skin care for laser and peel treatments]

Treating the signs of skin ageing or acne scars by chemical peels or ablative lasers is increasingly used worldwide. Due to their reduced invasiveness, these methods are often favored over aesthetic surgical interventions. Both procedures rely on the principle of controlled damage to the skin. The subsequent regeneration may lead to the development of new epidermal (and dermal) tissue and therefore improve the skin's aesthetic appearance. At present, there are no official guidelines in Germany concerning pre- and post-interventional skin care, which is currently based on the personal experiences and evaluations of the practitioner. It is known that an appropriate treatment regime can improve the outcome and reduces downtime pre- and post-laser as well as pre- and post-peel. The aim of this article is to present the different possibilities of pre- and post-interventional care. In most cases, priming includes intense ultraviolet (UV) protection, topical retinoids as well as skin brightening agents, and occasionally oral herpes simplex prophylaxis. In order to support post-interventional wound healing, skin care should modulate inflammation and balance skin hydration. In addition to light moisturizers, broad spectrum UV protection as well as the avoidance of sports and sweating are essential.
