Learn the correct order to layer Great Barrier Relief serum and Oat So Simple Water Cream for deep, lasting hydration without irritation.
Quick Answer
For maximum hydration, apply Great Barrier Relief serum first to soothe and repair your skin barrier, then follow with Oat So Simple Water Cream to seal in moisture. This order ensures your skin gets the reparative benefits of the serum while the lightweight moisturizer locks in hydration without feeling heavy. Always apply on damp skin for best results.

Layering skincare products correctly can make a huge difference in how effective they are. If you have sensitive or easily irritated skin, finding the right combination of products that hydrate without causing breakouts or greasiness is key. KraveBeauty's Great Barrier Relief and Oat So Simple Water Cream are two fan-favorites that work beautifully together, but only when applied in the right order.
In this guide, we'll walk you through the exact steps to layer these two products for maximum hydration, explain why the order matters, and highlight common mistakes to avoid. By the end, you'll have a simple, effective routine that keeps your skin calm, comfortable, and deeply moisturized.
Why Layering Order Matters
The general rule of skincare layering is to apply products from thinnest to thickest consistency. This allows each product to absorb properly and ensures that the active ingredients reach the skin without being blocked by heavier formulas. When you apply a thick moisturizer before a serum, the serum can't penetrate effectively, wasting its benefits.
In the case of Great Barrier Relief and Oat So Simple Water Cream, the serum is a reparative treatment with a lighter, more fluid texture, while the moisturizer is a creamy, water-based product designed to seal in hydration. Applying the serum first allows its active ingredients—like Tamanu Oil—to sink in and start repairing your barrier, and then the moisturizer locks in that moisture and provides an extra layer of comfort.
- Always apply on slightly damp skin to enhance absorption.
- Wait 30–60 seconds between layers to let each product settle.
- Use gentle, upward strokes to avoid tugging on sensitive skin.
Step-by-Step Layering Routine
Start with a clean face. After cleansing, gently pat your skin dry—leave it slightly damp. This helps the serum spread evenly and absorb better. Take 2–3 drops of Great Barrier Relief and press it into your skin, focusing on areas that feel tight or irritated. Allow it to absorb for about a minute.
Next, take a pea-sized amount of Oat So Simple Water Cream and warm it between your fingertips. Apply it over your entire face and neck, using gentle pressing motions. The lightweight, water-cream texture will feel cooling and soothing, especially on sensitive areas. Finish by gently pressing any remaining product into your skin to lock in the hydration.
- If your skin is very dry, you can add a few drops of facial oil after the moisturizer.
- Use this routine both morning and night for best results.
- Always patch test new products to ensure no adverse reactions.
Common Mistakes to Avoid
One common mistake is applying too much of each product. With Great Barrier Relief, a little goes a long way—over-applying won't speed up results and can leave a residue. Similarly, Oat So Simple Water Cream should be used sparingly; a pea-sized amount is enough to cover your face. Overloading your skin can lead to clogged pores and a greasy feel.
Another mistake is layering on completely dry skin. If your skin is dry, the serum may not absorb as well, and the moisturizer might sit on top rather than sink in. Always apply to damp skin to maximize hydration. Also, avoid rubbing or massaging too vigorously, especially if your skin is sensitive—gentle pressing is more effective and less irritating.
- Don't skip the waiting time between layers.
- Avoid using other active ingredients (like exfoliants) at the same time unless your skin is used to them.
- If you experience any stinging or redness, reduce frequency or consult a dermatologist.
Step-by-Step Layering Guide
- Cleanse and prep: Wash your face with a gentle cleanser and pat dry, leaving skin slightly damp. This prep step ensures optimal absorption of subsequent products. Checkpoint: Your skin should feel clean and slightly tacky, not bone-dry.
- Apply Great Barrier Relief serum: Dispense 2–3 drops of the serum onto your fingertips and press gently into your skin, focusing on areas of tightness or irritation. Allow it to absorb for about one minute. Checkpoint: Your skin should feel soothed and slightly hydrated, with no sticky residue.
- Follow with Oat So Simple Water Cream: Take a pea-sized amount of the water cream and warm it between your fingers. Apply over your entire face and neck using gentle pressing motions, avoiding the eye area. Checkpoint: Your skin should feel soft, hydrated, and comfortable, without any greasy after-feel.
- Seal it in (optional): If your skin is extremely dry or you're layering for nighttime, you can finish with a few drops of facial oil or a heavier moisturizer to lock in all the hydration. Checkpoint: Your skin should feel deeply nourished, but not suffocated.
