Do our skin and hair change every 7 years?


During my last Korean traditional anti-aging facial, beauty expert Han mentioned to me that women experience three major changes to their skin – during puberty, pregnacy and menopause.  I think biologically, this definitely makes sense since these are the periods when we encounter changes to our hormones too.  However, when I was speaking to Susan of True Beauty, she indicated that our skin changes every seven years! 

Important to know age for correct skin care analysis
Please note that I’m not discussing the epidermis, which sheds on a 28 – 30 days cycle but rather the entire skin which is made up of various layers.  In fact, I found several sources on the Internet which seem to confirm what Susan had said to me, in particular, this skin care document and this skin care consultation questionaire.  This also tells us why it is important for beauty experts or therapists to know our age before giving us a more accurate analysis.  I find it amazing that some of these people can comment negatively on my skin without first asking for my age.  I mean, on what basis are the comments made if they can’t quite tell my age?

The tipping point of aging
And of course I started thinking about my age in multiples of 7 and how they have changed too.  I cannot remember specifically at each stage but yes, there were some significant changes for some of those that I recall.  For example, when I hit 21, I noticed my skin becoming drier and I started on the Clinque 3-step skin care routine and the last time my age hit one of the 7 multiples, my skin took a nosedive and headed south!  You might also be interested to know that Futurederm, another beauty blogger, recently wrote an entry which indicated that 35 years old might be the tipping point of aging.  Coincidental or not, 35 is definitely one of the multiples of 7 isn’t it?

Body changes every 7 years
Well, apparently, it’s not only our skin that changes every 7 years, but our entire body chemistry.  So your hair, your teeth and your organs change every 7 years too.  I couldn’t find proper research material on this, but when I ran a search for “body chemistry changes every 7 years” or simply “body changes every 7 years” online, there were quite a number of discussions and articles found. 

Share your experience
So what do you think?  Do you remember how your skin or your hair changed when your age hit one of the multiples of 7?  If yes, did you develop a new allery?  Did you outgrow an allergy?  Did your skin type changed drastically?  What was it?

    I read an article on the 7 year cell changes too and vaguely remember that cancer cells take that long to be in remission (but that comes with a lot of other factors).

    With better knowledge of taking care our skin, hopefully we might end up having better skin every 7 years.

  2. Evah says:

    Well I’m only 21, so I can’t say that I’ve had enough experiences of changing skin every 7 years. But before I turned 21, my skin was super oily and I had moderately severe acne. Now at 21, I haven’t really had any bad break-outs but my skin is annoyingly dry.

  3. Renee says:

    Uh oh, I just turned 21! ? Thanks for another informative post, I find this very interesting (and Han is so sweet isnt she?). I’m not sure if my skin has ever drastically changed, but since 20 my skin has become very clear, before that I had suffered from zits and mild acne all my teen years. Hope this doesn’t change ?

  4. Blovet Beauty says:

    hmm.. looking back, i think my skin becomes drier at every 7 yr cycle. also, the pores aren’t as refined ? But I find that my tiredness shows up very easily on my face as I grow older… Sigh

  5. sesame says:

    Yesh…better skin every 7 years would definitely be great. ?

  6. sesame says:

    Good to know that yours has change for the better. Moisturizing and using a hydrating mask may help with your dry skin.

  7. sesame says:

    Great to know that your skin has also changed for the better and yeah, would definitely be nice for it to stay that way.

  8. sesame says:

    I think we all attribute these to aging…but hey, your skin looks good to me!

  9. Vonvon says:

    After giving birth to my little girl, I was approaching a multiple of 7, and indeed I notice my skin wasn’t as smooth as during pregnancy and before becoming pregnant. And body-wise….well, I have been battling with my weight since then…..

  10. Jyoan says:

    I am not so sure about this… The last time I had a multiple of 7, was during puberty, and of course, during puberty, my skin started to be able to develop acne. However, I was never really acne-prone or oily, maybe in fact, never oily.

    The other time when I reach multiple of 7, which was last year, honestly, nothing happened. Even until now, nothing happened.

    I have been a sensitive skin person since age 9? When my mum first tried to make me wash face, and bought J&J pH5.5 cleanser. Even at 9, without pimples, my skin grew red due to that.

    Till now, I have not grown out of any allergies. I still react to almost every bath foam and cleanser.

  11. Sukidoll says:

    Interesting, a while back I was sent to see a dental surgeon by my dentist due to a hard nob under my gums. He said I had bone sclerosis, but nothing to worry about. He booked me in for an appointment 7 years from then for a check up, after telling me our bones completely change every 7 years.

    Thanks for the post ?

  12. sesame says:

    Actually conceiving a child will change our body chemistry quite a lot…

  13. sesame says:

    The 7 years is probably not absolute for all…some may experience more changes, others may experience subtle changes.

    Woah, your skin is really sensitive…is it SLS that you’re sensitive to since you mentioned foam and cleanser?

  14. pf1123 says:

    Hmmm….I’m not sure. But its highly possible. If you realise, our body also became worse over 7 years e.g. more easily tired, PMS worse and worse. Haha…

  15. sesame says:

    Even bones huh…that’s really interesting indeed!

  16. sesame says:

    Yes, getting worse for sure! Brains too…I don’t know about others but mine is degenerating for sure!

  17. raelynn says:

    i’m 21.. not enough “7s” to do an accurate analysis too. but having been through 12 and approaching 21, i realise that the change might not just be from biological change. for example, at 14, there’s the oily and acne prone skin. when that happens, a lot of acne and oil control products are used to keep in in check (though i have to admit i used it excessively), which led to sensitive reactive and flushed skin for the next 3 4 years. now approaching 21, it’s slowly balancing the oiliness out, but it’s becoming dehydrated.

  18. stella says:

    i think lifestyle habits play a major role. from the age of 19-24/5, i did not exercise *at all* but then i had some lifestyle changes and worked out anything from 3-5x a week, definitely felt better. when i was 26-28, i slowed down to 1-3x a week due to other commitments, i felt a little less energetic but i can’t really tell if it’s lack of exercise or age. even at 31 now and sadly (due to work) back to age 21 lifestyle, i don’t feel any much different physically from 10 years ago. so really, i think if you lead an active lifestyle, you can keep your body – and thus skin – in tip top condition for sometime ahead. just slap on that sunscreen! … now i just need to get started again

  19. holly says:

    I’m in my early 40’s (yikes, time flies!) and up to 40 years of age, I was often mistaken for being a good 10 years younger than my age. But the last couple of years I’ve definitely seen a change in my skin, much drier etc. so I’ve had to re-boot my whole skin care routine..because at 50, I still want to look sensational. I think it’s alot about attitude, energy, nutrition, good skin care, and over-all health. But sometimes, you just have to relax & know that you’ll get older sure, but thank goodness you are still around to enjoy all that life has to offer, regardless what greets you in the mirror, life is for living.

  20. minsin says:

    I noticed i started to develop redness and some pimple at my early 20’s which it didn’t happened to me when I am in my teenager age.

    And my teenager age’s problem ( skin irritation with almost all type of allergen) just disappear.

    I think our body and skin trying to find way out of old problem but yet it too “young” and get itself into another new problem. It is so kinda of evolution process..

  21. eliza says:

    I guess it does
    when I was 7 I had silky straight hair, age 14 my hair was frizzy and unruly. But I hadn’t had any pimples or skin problems except my face getting oilier as I grew. Very bad pimples start pooping up at age 18, bad pimples ended at age 20 leaving scars ==’. I shall observe next year whether my skin changes for the better or not XD

  22. sesame says:

    Seems like dryer skin is common for those approaching 21…actually I can’t remember how my skin was like in my teens except that I didn’t have acne and pimples…but it was developing towards combination type I think.

  23. sesame says:

    Yeah, you’re right that lifestyle makes a difference. A lot of us are lazy and exercise can improve circulation and help to build collagen for us. I wish I’m more active!

  24. sesame says:

    So lucky! I wish I can look 10 years younger! I think the stress does add up and cause damage too so you’re right that relaxing and enjoying life help. ?

  25. sesame says:

    I read about people who outgrew their allergy after 7 years – skin or otherwise – so it’s interesting to learn of yours. Yes, what you said is apt – it’s a kind of evolution…sometimes we’re more aware, sometimes we’re not if the signs are subtle. I think perhaps it becomes more evident when we grow older.

  26. sesame says:

    Wow, your hair has changed drastically…that’s kind of surprising. Certainly hope your skin will look great when you hit 21 (I guess that’s your age next year?) ?

  27. Jyoan says:

    I thought it is SLS that I am sensitive to. But it I have been using an SLS containing product for some time now. And it seems to be no problem. Perhaps it is also the concentration that matters… … Things like Lux, Dove (though said to be gentle), all cannot.

    haha, I think I am still lucky enough to be not that sensitive. Just a few red bumps on hands… Compared to someone I know who will get whole body breakouts.

  28. Leon says:

    Hey Sesame, its so true now I realized why I got my first cystic acne when i was 28.

  29. sesame says:

    You did? I actually started developing more acne the last time I hit one of the multiples! My cheeks also became drier and there are open pores! ?

  30. sesame says:

    You’re probably right that it’s the concentration. I think those mass products tend to have more SLS.

  31. zhenling says:

    i developed acne and pores when i was fourteen. now closing in on 21 with more sensitive skin. i wonder if there is anything we can do to make our body chemistry better in the next cycle?

  32. sesame says:

    I think if we can understand how our body chemistry might change may help to alleviate. For example, when we get older, we may lack certain nutrients or vitamins, or some of our organs may become weaker and if we know that and act on it, it might help.

    However, this is easy said than done cos I find it hard to find out all the info and be on guard…plus there are also some of the unknowns and unpredictables which differ according to individuals.

  33. Leon says:

    Yeah Sesame, I too feel very bad about it:( I don’t recall any major changes on my skin when I hit 21 but I am sure it would have changed a bit.

  34. sesame says:

    Actually, this morning I thought about this again and I realized that the age I developed these red patches on my body was also in a multiple of 7! Just that it didn’t hit me at first cos I was also pregnant that time and I just attributed to the changes in hormones. I guess it’s both then or maybe coincidental…

  35. Carla says:

    What an interesting post! Dunno if it’s every 7 years. But I just turned 25 and for the first time in my life I stopped breaking out. Not even the occasional zit hehehe. Also, I had very very dry hair till the age of 20, really, it was like straw! And after that it completely changed and has been silky smooth ever since and I don’t even use conditioner or nothing. So there might be some truth in what you wrote. :p


  36. sesame says:

    Wow, another one with great changes to hair texture! It’s so amazing to hear your story because I seldom hear/read of pple whose hair has changed drastically. Very interesting!

  37. Leon says:

    Oh! Now I am more curious about this number 7 thing

  38. stiffedneck says:

    I guess this doesnt apply to me, or at least not so obvious. I’m now reaching 25, first time ever have acne. My hair’s getting drier for the last year, and I get tired so much quicker. I remember at 21, my skin was great and supple and so smooth; my hair was so easy to manage and always shiny; I just pretended to be tired to not do things (hahaha…my bad). But now, its the mid cycle and everything take a worse turn for me. Lets hope that when I reach 28, the cycle’ll be back like when I was 21 :-).

  39. sesame says:

    The cycle probably doesn’t apply to you absolutely. Yes, let’s hope everything goes back to normal in the next cycle! ?

  40. Cherrie says:

    Wow, I think there may be some truth in this. I had baby smooth, soft and radiant skin all along (runs in the family!), even thoughout my teenage years and I never had to deal with pimples, that is, till I reached 21.

    My pores get clogged easily now and I’ve lots of little bumps and the occasional pimple on my face ? As compared to the past, my tzone is no longer so oily though.

  41. sesame says:

    Hope whatever you’re experiencing is temporary and your skin might change for the better. But of course the best bet is to take care of it too. ?

  42. Lore says:

    very interesting post! it makes sense that our body changes since our cells are always regenarating.
    i had very straight silky hair until puberty, then my hair turned wavy.
    My skin remained smooth and clear until i was 20-21. i guess hormones and other health issues started causing changes because now at 25 i’m very acne-prone and my hair is still wavy and frizzy :S

  43. sesame says:

    Yes, they do. But I wish they’ll change for the better. ?

  44. herbal vigaplus says:

    Yes , your right… But we need to take care of our skin with Korean traditional anti-aging facial cream. Its really good

  45. Stacey says:

    I wondering if it changes life style. From the age of 4-16 I had a eating disorder and couldn’t bring myself to eat anything but cheese sandwiches. I was in poor health asa you can imagine. From 16-20 I began to eat other regular stuff, like meat, but again staying away from fruit and veg. Everytime I had any, I would gag and refuse to touch them. I’m now 21 and for the first time last night, I picked up an apple and ate it without even gagging. Now that was something huge for me! I was shocked and the thought I might have gotten over the fear of it. I was wondering if this could be something to do with this 7year change…

  46. kae says:

    Well I’m kind of scared of this peeling stuff because idk if it could be a disease or just the 7 year cycle because on my right hand the skin is peeling and I want to know what it is.
