As a listener to this show, you’ve probably heard of the gut microbiome. But did you know that your skin has its own microbiome?  Recent evidence suggests that these microbiomes are vital for our skin health. So, what should we do? Which foods make an impact?  And if we want our skin to look healthier, how about those collagen supplements that many of you have asked us about?  In today’s episode, our guest is Dr. Justine Kluk, a consultant dermatologist with a specialist interest in acne. Justine is a member of the British Association of Dermatologists, the Royal Society of Medicine, and the Royal College of Physicians.  ZOE’s Chief Scientist Dr. Sarah Berry also joins as a cohost to explore these ideas.  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:00 Intro 02:01 Quick Fire questions 03:52 What does skin do? 04:51 Why is the skin so important? 06:34 Is there a correlation between aging skin and health? 07:41 What is the skin microbiome? 11:46 Is exposure to the natural environment beneficial for children? 12:39 Can we change the skin microbiome? 13:32 Would an oral or topical probiotic help improve our skin microbiome 15:11 What can we do to help support the skin barrier? 15:39 Can overwashing/scrubbing disturb your skin? 16:40 Why does acne matter? 18:37 Is acne just found in teenagers? 19:12 What effect does menopause have on your skin? 20:36 What impact does diet have on acne? 22:14 Are diets with high glycemic content bad for acne? 23:01 What is happening to create the effects of acne? 24:23 Is there a connection between our gut health and skin health? 25:15 Practical advice for people with acne 28:16 Diet tips to help support healthy skin 29:51 How has the ZOE diet gone down in Jonathan and Justine's household? 32:54 How can the ZOE diet help with day-to-day cooking habits? 35:46 What causes skin aging? 37:44 What can we do to slow down skin aging? 39:55 Do collagen supplements work to keep your skin youthful? 41:52 How can retinol help your skin? 42:30 3 things that could help keep your skin young 43:31 Top nutrition skin myths 45:50 How important is it to apply sun protection? 46:36 How does stress impact our skin? 48:38 Questions for Jonathan 54:57 Summary & Outro Mentioned in today’s episode:  Mortality is written on the face from The Journals of Gerontology: Series A Too clean, or not too clean: the hygiene hypothesis and home hygiene from Clinical & Experimental Allergy Impact of outdoor nature-related activities on gut microbiota, fecal serotonin, and perceived stress in preschool children from Scientific Reports Justine shares more in-depth skincare and acne information at drjustinekluk.com and as @drjustinekluk on Instagram  Follow ZOE on Instagram.  Episode transcripts are available here.
