Background and Design: The skin properties of 98 postmenopausal women with hormone replacement therapy (oestradiol gel or patches) or without hormone replacement therapy were studied using non-invasive techniques: skin thickness with skin echography, skin hydration with a dryness score and measurement of capacitance, skin surface lipids with a Sebumeter® and microtopography with image analysis of cutaneous replicas. Results: In this open study we demonstrated an increase in skin thickness and sebum in the treated group in comparison to the untreated group (7–15% according to area for skin thickness, 35% for sebum). Hydration and microtopography were not different in the two groups. Conclusions: Postmenopausal women who were receiving hormonal substitution have a greater thickness and casual level than untreated women. We therefore suggest that hormonal aging exists and that cutaneous atrophy can be prevented with hormone replacement therapy.

Background: The use of nicotine replacement therapy (NRT) can almost double the chances of success for smokers to quit. Nevertheless, there is still a considerable number of cessation attempts that are made without any treatment. This novel oral formulation, (lozenge containing nicotine bitartrate dihydrate) has been developed to enlarge the offer for efficient smoking cessation drug therapies, assuming that increasing treatment options will bring more smokers to find the support they personally need to stop smoking.
