As someone with barely-there brows, the 2-in-1 Brow Styler is great for shaping and blending, but I still reach for my NYX Micro Brow Pencil to create those hair-like strokes and add extra definition. 🤎✨
The perfect combo? Micro Brow for precision + 2-in-1 Brow Styler for effortless finishing and grooming.
Some call it magic. I call it a science
Your skin barrier is built like a layered structure of oil and water.Think of it as a “brick and mortar” system:🧱 Skin cells = the bricks💧 Water = hydration inside the skin🧈 Lipids (ceramides, cholesterol, fatty acids) = the mortar that locks moisture inHealthy skin needs both oil and water to function properly. Too little water can leave skin dehydrated, while too little oil can weaken the barrier and allow moisture to escape.That’s why an effective moisturiser should help replenish both hydration and lipids, supporting the skin’s natural bilamellar structure.
Most people think dry and dehydrated skin are the same thing.They’re not.Think of your skin like a sponge.💧 Dehydrated skin = the sponge has lost water.It feels tight, looks dull, and can even become oily as your skin tries to compensate.🧈 Dry skin = the sponge is missing its protective coating.It lacks oil, feels rough, flaky, and struggles to keep moisture locked in.The key difference?Dehydrated skin needs WATER.Dry skin needs OIL.Let’s use the Byoma Moisturising Rich Cream as an example.💧 Glycerin = the water magnetThis humectant pulls water into the skin, helping relieve dehydration and keeping skin feeling hydrated.🧈 Shea Butter + Caprylic/Capric Triglyceride = the comfort blanketThese emollients soften skin and help reduce moisture loss, making them ideal for dry skin.🧱 Ceramide NP + Cholesterol + Phytosphingosine = the bricklayer teamYour skin barrier is naturally made up of lipids. These ingredients help support and replenish that barrier, helping skin hold onto both water and oil more effectively.So who is this moisturiser for?✔️ Dry skin✔️ Compromised skin barrier✔️ Anyone looking for a richer, nourishing moisturiserThis isn’t sponsored. I’m simply using Byoma to show how understanding ingredients can help you choose products with confidence.Follow along for more Ingredient to Aisle, where we break down what products actually do, not just what the packaging says.

Greece gave me the heat, this mist gave me the hydration. ☀️🇬🇷not sponsored
Hydrating Face Mist
After days of intense sun exposure, sea salt, flights, and temperatures that should have left my skin dehydrated, my skin still looks plump and hydrated.
The science is why.
Powered by Hydroviton® Insta, a multi-level moisturizing active derived from organic cucumber, it helps support Natural Moisturizing Factors, filaggrin production, and hyaluronic acid synthesis for deeper hydration and a stronger skin barrier.
Combined with AQUAXYL™, it optimizes water circulation throughout the epidermis while helping reduce transepidermal water loss by reinforcing essential lipids and proteins in the skin barrier.
Hydration isn’t just about adding water. It’s about helping skin retain it.
This was my most-used skincare product in Greece, and my skin is proof. 💧
