Skincare Science

Skincare Science

Last month, I had the good fortune to sit down with famed skincare scientist Jules Zecchino.

While his name may be unfamiliar, the products he’s developed are NOT. He developed Elizabeth Arden’s Ceramide capsules and Estee Lauder’s Perfectionist, among countless other products for both brands. Over lunch, I picked Jules’ brain about skincare essentials (on the ground and up in the air), his new company and products under development, and science in general.

This is one science lesson you won’t want to snooze through.


Save Emolliant Invest Emolliant Splurge Emolliant

Jules recommends against using a facial spray while in-flight – it may feel good, but does very little in terms of rehydrating your skin. Using an emollient will seal in moisture, and reapplying said emollient on the plane is the best thing you can do for your skin.

Tip – slather on a thick layer of Crème de La Mer from the duty free shop sample before boarding your flight and re-apply a less expensive version when in flight.


Save Collagen Invest Collagen Splurge Collagen

Topical collagen treatments are the BEST for instantly rehydrating your skin after a long flight. Masks are the best way to deliver said moisture, either through a sheet or paste. These treatments, however, do nothing to boost your own skin’s production of collagen (which decreases as we get older).


Save Peptides Splurge Peptides Invest Peptides

Peptides, most commonly found in serums, are great catalysts for our skin’s own collagen production. I’ve been using the Jack Black Protein Booster serum for two years with excellent results – couldn’t recommend it more highly.

Iron Oxide

Save Iron Oxide Invest Iron Oxide Splurge Iron Oxide

Prevention is key. There’s a reason that every skincare expert preaches regular use of a sunscreen daily (yes, even when it’s cloudy). Looking for zinc oxide and iron oxide in your products will protect your skin from both UVA and UVB rays. Apply it early, apply it often. Your skin will thank you.

    Loved this! I’ve got a couple of long-haul flights coming up and this answered questions I didn’t even know I had. :) (Loving your Quarterly boxes, too.)

      Thank you so much, Karen! I learned a TON from Jules and am excited to be featuring some of his latest and greatest inventions soon :)

  • Hi Hitha! I truly enjoyed this post. The way in which you broke down each ingredient lesson was very helpful- we should know what we apply to our bodies, no? I’m all for more beauty posts!

      Thank you for the wonderful comment, Kira! More beauty posts for sure!

  • I appreciate this so much! I’ve been chatting more and more about skincare on my site too – and you never really know what all of these terms mean. Thank you for breaking it down. xo

    • hithaonthego

      Thank you so much, Kimberly! I’ll be checking your latest beauty posts today. xo

  • Sandi

    I love a nice fluffy product post as much as the next girl, but rarely do you find posts with information on the key ingredients we should care about as beauty consumers. I love how this presented the facts a concise, clear way with recommendations in varying price ranges. All around great post! Thanks, Hitha!

    • hithaonthego

      Thank you so much Sandi! It was a fun post for me to write – I rarely get to use my chemistry knowledge these days, and it was fun to put it in a context that every woman can appreciate.

  • Jennifer

    Beautiful, perfect timing on this post! I have been searching for help with skincare. Now that I’m 45, it’s time to change some of my routine and products. This was so very helpful! Thank you for sharing!

    • hithaonthego

      Thank you Jennifer! I’m so glad you enjoyed this post!

  • Great post! However, I avoid all petroleum based oils like the plague — anything that says mineral oil, petrolatum, etc. I bought the Jack Black Protein Booster for Joe a few years ago and ended up using most of the bottle myself. It’s a good summer time serum!

    • hithaonthego

      I got the Jack Black serum recommendation from you! It’s been a mainstay in my beauty routine ever since. I’m still on the hunt for non-petroleum based products in emollients, besides good ol’ coconut oil. Got any recommendations?

  • I love these posts! Keep them coming!

    • hithaonthego

      Awesome, Patti! Will do!

  • Tammy

    This is amazing, Hitha! I love these science-beauty posts. I especially love the save/invest/splurge idea as well. Many bloggers don’t do this and it’s tough for me because I know that they were gifted those items to review = I love how realistic your posts are.

    • hithaonthego

      Thanks Tammy! I appreciate the kind feedback and will be bringing this same price point breakdown in upcoming outfit posts as well. It’s my goal to have you all looking and feeling great, no matter what your budget is :)

  • Hitha this was a FABULOUS post!! I’m a skincare nut and while I do agree that natural is better than weird chemical junk, I really want some science in my products because… SCIENCE. Love it! And I can’t wait to try some of these out, especially the protein boost.

    • hithaonthego

      Thank you so much! I’m OBSESSED with the Protein Boost – it’s one of those products that I constantly restock and won’t try another. Let me know what you think about it!

  • Stefanie

    Hitha this is seriously an amazing post! I can only imagine how much time went into it, but man was it worthwhile. My question is around the Collagen/Peptide arena- sounds like if I want to increase my collagen production I should invest in a good peptide and call it a day. Is there a benefit to then using a collagen?


    • hithaonthego

      Excellent question! Peptides should be a part of your daily skincare routine to keep your body’s collagen production high, and collagen products should be used after a long flight or any time your skin feels really dehydrated. So peptides every day, collagen when you need it.
