Hydrating vs. Moisturizing: What's The Difference?

Cracked, flaky, peeling skin just means it’s dry, right?


Not necessarily. Just because your face feels like the Sahara Desert doesn’t mean it’s simply dry. Your skin might actually be dehydrated, meaning it lacks water — whereas dry skin lacks oil and needs to be moisturized.

The distinction is important: here’s why.

3 signs your skin is dry

  • Your entire body feels dry, and you constantly need moisturizer
  • You have no natural sebum (oil)
  • Your skin feels dull, flaky, itchy, and tight

The best treatment for dry skin

Keeping very dry skin moisturized can seem like a full-time task. Make sure you apply moisturizer from head to toe. Here are Dr. Sandra Lee’s favorite dry skin hacks:

For face

Use a moisturizer with antioxidants. SLMD Skincare Facial Moisturizer contains vitamin C, to boost collagen production and protect the skin from environmental stressors.

Add niacinamide to your routine. This potent B vitamin strengthens your skin barrier and helps regulate sebum production. Try it in SLMD Skincare All Bright Niacinamide Brightening Toner.

Don’t skip the sunscreen. Protecting your skin from damaging, inflammatory UV exposure will keep your complexion less stressed. SLMD Skincare Daily Moisturizer with SPF 15 does double duty in a lightweight, nourishing formula.

For body

Start with a good scrub. SLMD Skincare Glycolic Acid Body Scrub uses both physical and chemical exfoliants to slough off dead cells gently yet effectively.

Stash body lotion in the shower. Applying SLMD Skincare Glycolic Acid Body Lotion to damp skin locks in moisture. This body lotion combines exfoliating glycolic acid with moisturizing ingredients like shea butter.

Dehydrated skin before treatment with Glycolic Acid Body Lotion by SLMD Skincare

4 signs your skin is dehydrated

  • Your skin feels oily and dry simultaneously
  • Your skin tends to change texture based on your environment, the products you use, and your diet
  • You tend to break out occasionally and unexpectedly
  • Your skin is dull, congested, and flakes easily

If you’re still not sure your skin is dehydrated, try the pinch test: pinch your skin between two fingers. If it bounces back (meaning it lays flat again) right away, you’re hydrated. If it takes longer to fall, it’s likely you’re dehydrated.

It’s worth noting that your skin doesn’t have to fall into the dry skin type to be dehydrated. Combination and oily skin types can also experience dehydration.

The best way to treat dehydrated skin

  • Drink plenty of water. You’ve heard it before: your body is mostly water, so skin suffers if you’re deficient.
  • Eat a balanced diet with healthy fats like avocado, olive oil, salmon and nuts, which are high in omega-3, to improve the overall health of your skin
  • Wash face in warm — not hot — water. Hot water can dry out skin by opening pores and allowing moisture to escape.
  • Hydrate and moisturize your skin. SLMD Skincare Hyaluronic Acid Serum is a great combination hydrator + moisturizer, made with both hyaluronic acid and squalane — an ideal two-in-one combination for treating parched skin.
