What about smoking on acne?<\/h1>\n

\"tobacco\"<\/p>\n

Tobacco is harmful to the skin, we know today that it promotes early aging (with more wrinkles and more marked) and is responsible for a dull and blurred complexion.<\/p>\n

Le tabac favorise-t-il l’acn\u00e9?<\/h2>\n

If the answers to this question are sometimes contradictory, studies show that it would finally favour retentional lesions, i.e. dilated pores, blackheads and microcysts, but that it would have an antiflammatory action and would therefore protect against papules and pustules.<\/p>\n

Tobacco, and in particular the nicotine it contains, increases the differentiation and proliferation of keratinocytes, i.e. the cells of the skin. The excretory ducts of the sebaceous glands become \"keratinized\" and thicken, hindering the flow of sebum and obstructing the pores: open comedones (blackheads) and closed comedones (microcysts) are formed; in general, the skin thickens and the complexion becomes blurred<\/p>\n

The effects of smoking on wound healing<\/h2>\n

This is particularly true for teenagers, but also for some adults, where acne is favoured by other factors such as genetic factors, hormonal<\/a>, food<\/a> or the stress<\/a>, le tabac appara\u00eet alors comme un cofacteur aggravant. De plus, il ralentit la cicatrisation et\u00a0 aggrave ainsi\u00a0 les marques et cicatrices d’acn\u00e9. La nicotine<\/strong>\u00a0 \u00e9tant une substance vasoconstrictrice, \u00a0elle r\u00e9duit l’afflux sanguin au niveau de la peau et freine ainsi \u00ab\u00a0l\u2019apport \u00a0de mol\u00e9cules r\u00e9paratrices \u00bb. Les marques d\u2019acn\u00e9, form\u00e9es notamment quand un bouton a \u00e9t\u00e9 perc\u00e9 ou excori\u00e9, s’effacent donc beaucoup plus lentement si l\u2019on fume\u2026<\/p>\n

Si le tabac semble avoir des cons\u00e9quences sur l’aggravation de l’acn\u00e9, ses effets n\u00e9fastes sur les l\u00e9sions inflammatoires pourraient d\u00e9pendre de la dose quotidienne fum\u00e9e. A forte dose (plus de 20 cigarettes par jour), le tabac aurait une action anti-inflammatoire en inhibant notamment la formation de prostaglandines et emp\u00eacherait la formation de \u00ab\u00a0boutons rouges. Mais cela ne veut surtout pas dire que le tabac est protecteur de l\u2019acn\u00e9 et rappelons nous qu\u2019il tue en France chaque ann\u00e9e environ 73000 personnes uniquement pas cancers sans compter les accidents cardiovasculaires.<\/p>\n

Although smoking does not directly cause acne, it aggravates it and promotes scarring.<\/p>\n
