Hello Dr Irwin, I got here throughout your web site doing google search to study sunscreens. Your web site is unimaginable and really informative, and your non-biased web site may be very a lot appreciated. I stay in Phoenix which has climate that goes from heat to sizzling and usually very dry. My query is relating to the usage of hyaluronic acid to assist my 47 yr outdated getting old pores and skin. I’ve tried completely different manufacturers and embody Clinique in addition to on-line manufacturers. I’ve delicate, pimples inclined pores and skin and have bother with the smaller molecule measurement of hyaluronic acid inflicting pimples. I’ve observed that irrespective of the model, my pores and skin is at all times drier after placing hyaluronic kind cream in my face. It occurred to me that our air is drier right here in Phoenix and has no moisture for hyaluronic acid to drag from. I attempted bedside humidifier in a single day however did cease the overdrying of my pores and skin. I’ve stopped the hyaluronic acid fully and gone again to moisturizers which helps me trying youthful. Would you be capable of present recommendation for all of us that stay in very dry climates and use of hyaluronic acid merchandise for each Zits inclined and non-acne inclined pores and skin? Thanks in your again and again, I like your web site and so glad I discovered it!
You made my day! Generally I get that author’s factor, the place the writing simply goes out into the universe, and I don’t know the place it lands. It helps to get suggestions. ?
Concerning topical use of hyaluronic acid (HAs), it’s often simply listed on the ingredient listing as hyaluronic acid. Molecular weight (MW) will not be specified . From what I can glean from the medical literature, the very low MWs can a be drying as a result of they enhance water loss throughout the barrier layer (dermis). They thus are drying. And conversely, the upper MW kinds or “resistent” types of HA lower pores and skin water loss. They’re then moisturizing.
For the pores and skin nerds amongst us, that is referred to as a lower or enhance in transepidermal water loss (or TEWLs). I’ll do extra analysis on particular merchandise to see if I can discover a solution to advocate a couple of for pores and skin sorts.
Zits and HAs
Usually, I can’t consider a case of pimples that I’ve seen that was aggravated by HA serums. HA is best in a serum kind as a result of the focus might be increased and there’s no oil. HAs in lotions may definately worsen pimples relying on what’s within the base. Lotions usually have oils within the base. Since pimples in ladies and men may be very hormonal, it’s very potential that the pimples outbreak had extra to do with hormone shifts, or a rise in inflammatory meals, then something within the HA serum. It may be powerful to pin down the precise reason behind an pimples flare.
Backside Line for HA use:
- Purchase the serum, not the lotions
- In the event you’re dry, or dwelling in a really dry local weather. Wash your face with a really mild cleanser that doesn’t strip moisture just like the Eminence Lemon Cleanser. Then apply an excellent serum like this one, then your moisturizer, after which your moisturizing sunscreen. Similar factor at evening, however you don’t want the sunscreen, and chances are you’ll must reapply sunscreen or moisturizer noon if it’s actually dry.
- Search for moisturizers to go over the HA serum which have natural oils or ceramides in them.
Hope this helps,
