The 4 Best Supplements For Dry Skin

1. Collagen: For Elasticity and Moisture

Collagen is a vital protein that helps maintain skin’s elasticity and moisture. As we age, our body’s natural collagen production decreases, which can lead to drier, less supple skin.

  • How it Helps: Supplementing with collagen can help improve skin hydration and reduce the appearance of dryness (1).
  • Supplementing Tips: Look for hydrolyzed collagen supplements for better absorption.

2. Biotin: The Building Block of Healthy Skin

Also known as Vitamin B7, biotin is integral to skin health. It plays a role in the production of fatty acids that nourish the skin and help to maintain its moisture barrier. A deficiency in biotin can lead to a variety of skin issues, including dryness and irritation (2).

  • How it Helps: Biotin supports the production of fatty acids that nourish the skin, helping to maintain its moisture barrier.
  • Sources: Besides supplements, biotin can be found in eggs, nuts, and whole grains.

3. Omega-3 Fatty Acids: A Hydration Powerhouse

Omega-3 fatty acids, found abundantly in fish oil, are essential for maintaining healthy skin. They are known for their ability to support skin barrier function (3). EPA and DHA in particular are thought to nourish the skin by helping to maintain its lipid barrier, which is essential for retaining moisture and protecting against irritants. Thus, they play a key role in skin hydration, preventing dryness and flaking. Omega-3s also possess anti-inflammatory properties, which can help reduce redness and irritation associated with dry skin.

  • How it Helps: Omega-3s strengthen skin cell membranes, ensuring that they retain moisture effectively.
  • Recommended Intake: Incorporate fatty fish into your diet twice a week or consider a high-quality fish oil supplement.

4. Probiotics: Balancing the Skin’s Microbiome

The health of the gut microbiome is increasingly recognized as being linked to skin health. Probiotics are beneficial bacteria that can help balance the gut microbiome, which in turn may positively impact skin hydration, barrier function, and health. They may also help reduce skin inflammation and sensitivity (4).

  • How it Helps: Probiotics can improve the skin’s barrier function, reducing dryness and sensitivity.
  • Consumption: Available in supplement form or through probiotic-rich foods like yogurt and kefir.


Treating dry skin effectively involves more than just external care; it requires internal support as well. Supplements like Collagen, Biotin, Omega-3, and Probiotics can provide this internal support, helping to enhance your skin’s hydration and overall health. Remember, it’s always recommended to consult with a healthcare professional before starting any new supplement regimen.
