This Is Why Your Skin Is So Dry (and What to Do About It)

Address these underlying causes, and you'll probably need less moisturizer.

Got dry skin? More moisturizer is not the answer!

At least it's not the ONLY answer. When you're dealing with dryness, there's often more going on than just a lack of product. 

In this article, I want to draw your attention to 12 other factors that can be involved in dry skin. (Not including the weather, because there's not much we can do about that!)

You will learn:

  • The physiological causes of dryness
  • Where you might be going wrong in your routine
  • The products that can cause dryness vs. treat it
  • How moisturizer can affect your skin long-term

You may just find that you need less cream after addressing some of these!

Vitamin A Deficiency

Vital Proteins Beef Liver may help correct vitamin A deficiency, which is linked to dry skin.

If you're low in vitamin A (and most people probably are!), it can cause skin cells to shed too quickly, resulting in dryness. 

This is known as abnormal keratinization, and vitamin A helps by slowing things down, so skin cells function longer before they flake off.

Food sources are always best, and you can find vitamin A in the highest quantities in liver, butter, cream and eggs. Otherwise, you might consider taking a low-excipient oral supplement such as:

Low Thyroid Function

Hypothyroidism: The Unsuspected Illness by Broda O. Barnes, M.D. and Lawrence Galton explains how low thyroid is connected to dry skin.

Low thyroid causes dryness (among other skin issues) because of poor circulation, especially in colder weather. 

According to Dr. Broda Barnes in his book, Hypothyroidism: The Unsuspected Illness:

"In hypothyroid patients, blood circulation through the skin is less than normal at all times and is reduced even further in cold weather since at that time more blood is shifted away from the skin and to the interior of the body in order to preserve body heat."

Keep in mind that it's very possible to be functionally hypothyroid, even if blood tests indicate normal thyroid function. Dr. Barnes (who is considered the pioneer of thyroid research) deemed lab tests "unreliable" and claimed 40 percent of Americans were in fact hypothyroid. That was back in 1976, so imagine how high that number is today!

If you'd like to learn more, his book is an excellent place to start.

Not Exfoliating 

Foreo Luna 2 for Sensitive Skin gently exfoliates dry skin.

If you think dry skin types shouldn't exfoliate, think again. 

Dry skin still needs regular gentle exfoliation, in order to remove dead cells. If they remain stuck on the surface, your products won't be able to reach and hydrate the LIVE cells, where they're needed—so you'll just be wasting your time (and product!).

Here are a few of my favourite gentle methods:

Exfoliating Too Much

With 25 percent AHAs and 2 percent BHAs, Drunk Elephant T.L.C. Sukari Babyfacial is not suitable for dry skin. 

On the flip side, make sure you're not over-exfoliating, either. I would avoid grainy scrubs and nylon cleansing brushes, which can be too aggressive, drying and irritating. 

Obviously, you want to be cautious with acids. (So, Babyfacial is probably not for you!) I think mild salicylic or lactic acids are the best choices for dry skin. In general, AHAs are more inflammatory (read more about that here).

How often should you exfoliate? For dry skin, I think three times a week is a good number. As always, it's a matter of self-experimentation to find the product and frequency that works for you.

Harsh Actives

Skin Inc. Vitamin B3+ Serum is a niacinamide treatment that is ideal for dry skin.

Many active ingredients, including acids, retinol and vitamin C, can be drying. Even more so if you're using multiples!

I know it's tempting, but you don't have to use every active, all the time, to get results. You can always rotate them at different times of day, on alternate nights, or even by the seasons.

Also consider these alternatives:

Sulfate-Based Cleanser

Dr Roebuck's Cleanse Natural Nourishing Crème Cleanser will cleanse dry skin without stripping.

Definitely avoid anything with sulfates, which are harsh cleansing agents that irritate and aggravate dryness. The most common ones you'll see on labels are sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).

Some of my favourite sulfate-free cleansers for dry skin include:

Whatever you use, make sure to thoroughly remove it—even micellar water, I recommend rinsing off. Leftover cleanser residue can dry out your skin (not to mention cause breakouts).


To minimize the drying effects, keep showers short and lukewarm. Optional: Shhhowercap Shower Cap!

They feel so good, but long showers at hot temperatures can cause dry skin on your face (and body!). This is because they strip away our natural protective oils, which allows moisture in the skin to escape. 

Washing your face at the sink instead, in lukewarm water, would be a good start. But also keep in mind that water itself can have a drying effect, whether it's hot, warm or cold. So keep that part of your routine quick!

Note: Drinking more water won't hydrate your skin.

Letting Your Skin Dry

Consonant HydrExtreme is a natural hydrating serum that is perfect for dry skin (or any skin).

Make sure to apply your hydrators right after cleansing, while your skin is still damp. 

This is especially important in winter. When the air is dry, it pulls the moisture out of your skin more quickly. This happens as soon as you finish washing your face or step out of the shower—because there's more moisture in your skin than the air! 

So you want to trap that water in your skin, before it evaporates and causes dryness. The hydrating serums and essences with the best ingredients include:

Only Using Humectants

LXMI creme du Nil is an effective silicone-free moisturizing cream.

Humectants are water-attracting ingredients like hyaluronic acid and glycerin. But on their own, they aren't enough for dry skin.

You need to seal them in with something more emollient or occlusive, like a cream or oil—or both! Some of my top picks include:

One intriguing ingredient is snail secretion filtrate, which is both a humectant AND an emollient. You can find it in COSRX Advanced Snail 96 Mucin Power Essence.

Only Using Oils

Omorovicza Instant Perfection Serum is a lightweight, hyaluronic acid-based serum.

Oils lock in existing moisture, but if you don't have enough in your skin to begin with, they won't solve dryness. 

(Squalane has a finer molecular structure, so it's a bit of an exception to this rule.) 

For dry skin, use a humectant and/or emollient underneath an oil. Again, these would be your serums, essences and creams. I mentioned a few above; here are some more I like:

Applying Products in the Wrong Order

Drunk Elephant Virgin Marula Luxury Face Oil is an oil suitable for dry skin.

Apply your products in order of lightest to heaviest texture. 

One of the biggest mistakes I hear about is putting oil on too soon. This can prevent other ingredients from penetrating, resulting in dryness. 

If you're using any treatment products like niacinamide or vitamin C, those would go on bare skin after cleansing. Next would come your serums or essences; then cream; then oil.

So use your oil last—it will also form a barrier that will help protect you from the elements!


Sappho Essential Foundation is one of the only silicone-free liquid foundations on the market, so it won't dehydrate your skin like most other formulas.

Silicones are present in most beauty products because they're inexpensive and create a silky, supposedly "luxurious" texture. Since they fill in crevices and form a surface seal, it may initially seem like they're effective at moisturizing.

They're not. As I explained here, silicone ingredients don't actually hydrate, they just protect from water loss. What's worse, they may even CAUSE dryness over time, by dehydrating your pores and interfering with cellular renewal processes. 

All the products I've mentioned above are silicone-free, but don't forget your makeup! My favourite silicone-free foundations and concealers are:


Address the root causes, and you may find your skin isn't dry after all.

If you're suffering from dryness, I hope these tips get you on your way to moist, dewy, hydrated skin again!

My position is that it's better to address the root causes of dryness, rather than always chasing the problem with moisturizing creams.

In fact, I'm not really a fan of using creams on a long-term basis. Even a well-formulated one could interfere with barrier function and cell renewal by keeping your skin too "wet," according to this study

So maybe you need one at this point in time, but that may not be the case after you tweak your diet or routine. As I explained here, I don't like boxing people into "skin types." You may have dry skin now, but you're not necessarily destined to have it forever. 

Let me know if these tips work for you!
