  • Can skin be dry for any other reason besides water loss?

    Posted by DaveStone on October 14, 2021 at 1:24 am

    A section of my forehead has somewhat rough skin (wasn’t always like that). The rest of my face isn’t scaly, but usually looks and feels quite dehydrated. I try to stay hydrated and use a good moisturizer every day. I wash my face with a mild cleanser. Now lately I have been using a highly humectant tonic followed with Vaseline. Rather than standard glycerin…I use better water-holding ingredients like Sodium Lactate and low-molecular weight Hyaluronic acid. But they’ve made no permanent difference over the course of a month or so. Does it take a long time to repair? Any better way to remedy dried-out skin? Would tretinoin help?

    tretinoin may make it dry. 

    One reason can be lipid loss. 

    One reason can be a disease.

    One reason can be your mild cleanser. What are the ingredients of this?

    Try to use low pH moisturizer and products. pH 4 or below.

    @DaveStone Dry skin and dehydrated skin conditions are not interchangeable meanings. Dehydrated skin - is water deficiency ( when skin is losing its ability to retain water) while dry skin is a sign of the decreased or abnormal lipid synthesis in the skin. TEWL takes place in both conditions. 
    If your moisturizers and occlusive preparations are obviously useless, it might be the dry skin condition. There are plenty of methods to maintain the lipid content and production in the epidermis. Light acid peels and Nicotinamide, for instance, show good results. 
    Be careful with Tretinoin. I would use it only after the consultation with a dermatologist.

    The cleanser I’ve been using lately is Cerave: Aqua / Water / Eau, Cocamidopropyl Hydroxysultaine, Glycerin, Sodium
    Lauroyl Sarcosinate, Peg-150 Pentaerythrityl Tetrastearate, Niacinamide,
    Peg-6 Caprylic/Capric Glycerides, Sodium Methyl Cocoyl Taurate,
    Propylene Glycol, Ceramide NP, Ceramide AP, Ceramide EOP, Carbomer,
    Methylparaben, Sodium Chloride, Sodium Lauroyl Lactylate, Cholesterol,
    Disodium EDTA, Propylparaben, Citric Acid, Tetrasodium EDTA, Hydrolyzed
    Hyaluronic Acid, Phytosphingosine, Xanthan Gum.
    Before that I used Dove Beauty Bar, which is what I use on the rest of my body. The PH of that is apparently 7. I read some online sources that claim Cerave’s PH is 5.5.

    I don’t know how to classify my skin condition. I don’t have flakes/peeling so it’s not dry in that sense.

    I haven’t tried acid peels but will give them a shot. Is mandelic acid any good? There’s so many acids out there now. Niacinimide is in my tonic, around 3%.

    @DaveStone Mandelic acid may work great. However, it is quite difficult to recommend something particular distantly. I assume you may want to see your dermatologist to determine the exact skin condition.

    This leads me to another question…can skin ever be over-hydrated? Say you used a blend of 50% water and 50% hyaluronic acid (which already has the best water-holding capacity) with a 100% occlusive. Could that be too much water for skin to take?

    It can be overhydrated when the skin is exposed to water, for example shower or foot baths. Hyaluronic acid works only on the surface while you need to  enhance water retention in the Stratum Corneum. Components of the natural moisturizing factor, such as Lactic acid, Urea, etc would be highly efficient along with polyols, sugar alcohols, etc.

    Us that Dove or a face wash with more anionic and less amphoteric surfactant to wash your face too and see if it gets better. 

    I haven’t used sultaine at high levels but CAPB at high level can cause skin to become dry and then very oily in reaction.

    The Dove bar has CAPB though I don’t know how much.

    Sodium Lauroyl Isethionate, Stearic Acid, Lauric Acid, Sodium Oleate, Water (Eau), Sodium Isethionate, Sodium Stearate, Cocamidopropyl Betaine, Fragrance (Parfum), Sodium Laurate, Tetrasodium Etidronate, Tetrasodium EDTA, Sodium Chloride, Kaolin or (ou) Titanium Dioxide.
