Sensitive skin and dehydration often stem from the same issue: a compromised skin barrier. When the barrier is weakened, skin loses moisture more easily, becomes more reactive, and can be harder to hydrate effectively. This guide explains the connection between sensitivity and dehydration, the ingredients that support barrier repair, and the simple routine changes that help restore comfort, resilience, and lasting hydration.

Ectoin and hyaluronic acid are both powerful hydration ingredients, but they work in very different ways. Hyaluronic acid draws water to the skin’s surface for fast, visible plumping, while ectoin anchors hydration around skin cells, supports the skin barrier, and helps protect against environmental stress. If your skin is simply dehydrated, hyaluronic acid is a great starting point. If it feels sensitive, reactive, or barrier-compromised, ectoin may be the better choice - or use both for complete hydration support.

Dry skin does not mean skipping SPF. It means choosing the right one. Many sunscreens are formulated for oily or combination skin, using lightweight gels and high-alcohol bases that can leave dry skin feeling tight, flaky, or uncomfortable. The good news?

In this guide, we break down exactly what to look for in an SPF for dry skin - from barrier-supporting ingredients like Polyglutamic Acid, Glycerin, and Squalane to the textures and formulas best avoided - plus how to layer your routine correctly for hydrated, protected skin every day.

Mineral vs chemical sunscreen: one of skincare’s biggest debates - and one of its most misunderstood. Both protect effectively against UV damage, but they differ in texture, finish, and wearability.

Think of the epidermis as your skin's suit of armour—its first line of defence. The condition of your skin’s barrier is closely tied to the overall health and appearance of your skin.
