Did you know that the skin is our body’s largest organ? With our skin exposed to daily environmental stressors such as pollutants and UV radiation, it could lead to lasting skin concerns such as wrinkles, hyperpigmentation, and increased vulnerability to skin diseases. Furthermore, improper care can exacerbate these risks.

Proper skincare is essential for maintaining healthy skin and preventing various skin concerns and diseases.

Learn how to strengthen your skin barrier with these essential tips for a radiant complexion!

What does the skin barrier do?

The outer layer of our skin (stratum corneum), also known as the skin barrier, plays a vital role in maintaining the skin barrier function. It prevents water loss and protects against external threats such as air pollutants, pathogens, allergens, and irritants.

What are some common issues that affect the skin barrier?

When the skin barrier is compromised, various skin problems may arise. This includes dryness, sensitivity, and an increased vulnerability to environmental damage. Additionally, acne may be exacerbated due to irritation and inflammation caused by a damaged skin barrier.

The skin barrier can be impacted by several factors:

  • Prolonged sun exposure
    Extended exposure to harmful UV rays can affect skin elasticity and collagen production, weakening the skin barrier.
    Sun exposure
  • Harsh climates
    Extremely hot or dry climates may strip the skin of its natural moisture.
  • Use of harsh cleansers or exfoliators
    The use of abrasive facial skincare products may disrupt the skin's natural lipid barrier.
  • Ageing
    As we grow older, the skin's ability to repair itself and maintain moisture becomes weaker.

How do I achieve healthy skin barrier?

  1. Hydration is key
    Ensure moisturiser or lotion is applied daily to keep your skin well-hydrated. Pay attention to products that contain ingredients such as hyaluronic acid and glycerine, as they help retain moisture levels.

  2. Avoid over-exfoliation
    While exfoliation can be a game changer for your skin, it is still crucial to find the right balance. Too much exfoliation can damage the skin barrier. Stick to a gentle exfoliation routine by steering clear of granular scrubs and opting for chemical exfoliants like AHAs or BHAs.
  3. Get sun protection
    Apply a broad-spectrum sunscreen with at least SPF 30 or higher to shield your skin from harmful UV rays. Re-apply according to the manufacturer’s instructions if you are outdoors for an extended period, especially after swimming or perspiring.
  4. Consume antioxidants
    Skin supplements or foods containing antioxidants of vitamins C and E can help protect the skin from free radicals, thus promoting a healthier skin barrier and complexion. Nutrient-packed foods such as oranges, tomatoes, broccoli, avocados, and dark leafy vegetables are excellent sources of antioxidants.

Protecting your skin barrier requires a lifelong dedication to effective skincare and healthy lifestyle habits. This includes staying hydrated, maintaining a balanced diet, and prioritising regular sleep routine to optimise skin regeneration.

By incorporating these habits into your routine, you will achieve clearer and glowing skin in no time. Take control of your skin health today!
