Learn the order to layer ILIA's Sun Serum Mineral Sunscreen SPF 50 and True Skin Radiant Priming Serum for a dewy, protected base that lasts.
Quick Answer
For a radiant glow, apply True Skin Radiant Priming Serum first, let it absorb, then finish with Sun Serum Mineral Sunscreen SPF 50 as your last skincare step. This order ensures the primer's skin benefits sink in while the sunscreen forms an even protective layer. Both products layer well under makeup without pilling.
A glowing complexion starts with skincare that pulls double duty. ILIA's Sun Serum Mineral Sunscreen SPF 50 and True Skin Radiant Priming Serum are two products designed to work together, but the order you apply them matters. Getting the sequence right means you get both sun protection and a smooth, luminous base for makeup.
This guide walks you through a simple routine that layers these two formulas effectively, so you can enjoy the benefits of each without compromising your glow.
Why Order Matters: Primer Before Sunscreen
Skincare layering follows a simple rule: thinnest to thickest, and active treatments before occlusive protectors. True Skin Radiant Priming Serum is a water-based serum that delivers ingredients like Hibiscus Extract and Beta-Glucan. These need to reach your skin directly to work effectively. Sunscreen, on the other hand, is designed to sit on the skin's surface and form a protective film. If you apply a thick primer over sunscreen, you risk breaking that film and reducing protection.
When you apply the priming serum first, it can absorb fully and do its job—firming, moisturizing, and smoothing. Then, the mineral sunscreen creates an even shield on top. This order also helps makeup apply more smoothly because the sunscreen acts as a barrier that grips foundation and concealer.
- Checkpoint: Wait 2–3 minutes after the serum before applying sunscreen to let it absorb.
Step-by-Step: Building Your Glow Base
Start with clean, dry skin. Dispense a small amount of True Skin Radiant Priming Serum—about a pump or two—and press it into your face and neck. Give it a minute to sink in; the serum has a lightweight feel and shouldn't leave a sticky residue.
Next, shake the Sun Serum Mineral Sunscreen SPF 50 well. This mineral formula has a water-burst texture that needs a good shake to blend evenly. Apply about two finger-lengths of product to your face, spreading it in smooth, outward strokes. Don't rub aggressively; let it settle into an even layer. The formula is designed to quench dryness and control oil, so it shouldn't feel heavy.
- Common mistake: Applying sunscreen too sparingly. Use enough to cover your entire face—most people need at least a nickel-sized amount.
Makeup Application Over the Glow Base
Once your sunscreen has set for a few minutes, you can layer makeup on top. The Sun Serum's weightless feel means it won't disturb your foundation or concealer. If you're using a full-coverage base, apply it with a damp sponge or a stippling brush to avoid moving the sunscreen around.
For a no-makeup makeup look, you can stop here—the priming serum's radiant finish and the sunscreen's subtle glow might be all you need. If you want extra coverage, follow with a concealer like Skin Blur Serum Concealer, which self-sets and doesn't require powder, keeping the dewy effect intact.
- Checkpoint: If you notice pilling, you may be applying too much product too quickly. Slow down and let each layer dry.
Your 3-Step Glow Routine
- Prep with True Skin Radiant Priming Serum: Apply a pump or two to clean skin, pressing gently. Let it absorb for 2–3 minutes. This firms, moisturizes, and smooths while protecting against environmental stressors. Checkpoint: Skin should feel hydrated but not sticky before moving on.
- Shake and Apply Sun Serum Mineral Sunscreen SPF 50: Shake well, then apply a generous, even layer over the serum. Use smooth strokes and allow it to set for 2–3 minutes. This provides SPF 50 protection plus up to 24-hour hydration and 8-hour oil control. Checkpoint: No white cast? You've blended well. Wait until it feels dry before makeup.
- Layer Makeup or Go Bare: If wearing makeup, apply foundation or concealer with a damp sponge. For a minimal look, stop here and enjoy the natural glow from both products. Verdict: This routine gives you a dewy, protected base that lasts through the day.
