ILIA Super Serum Skin Tint SPF 40 — Formosa ST4 light warm, lightweight hydrating coverage, mineral sun protection (1 fl oz)

ILIA Super Serum Skin Tint SPF 40 in Formosa ST4 is a lightweight, hydrating skin tint that combines sheer-to-medium coverage, mineral SPF 40, and skin-conditioning ingredients for a natural, dewy finish.

Designed to act like makeup and skincare in one, this award-winning skin tint evens skin tone while delivering broad-spectrum mineral sun protection. The formula blends hyaluronic acid, niacinamide and plant-based squalane to hydrate, refine texture and support skin elasticity without feeling heavy or clogging pores. Fragrance-free, vegan and dermatologist-tested, the tint is available in a wide range of shades—Formosa ST4 is described as a light shade with warm undertones and comes in a 1 fl oz (30 ml) pump bottle.

How does this skin tint protect and treat skin throughout the day?

The Super Serum Skin Tint uses mineral SPF 40 to provide sun protection while active ingredients work to improve skin appearance over time. Hyaluronic acid attracts and retains moisture, niacinamide helps minimize the look of pores and uneven tone, and squalane supports barrier hydration.

• Mineral SPF 40 for broad-spectrum sun defense
• Hyaluronic acid for immediate hydration and plumping
• Niacinamide to refine texture and balance tone
• Plant-based squalane to lock in moisture without greasiness

What coverage and finish can I expect when using Formosa ST4?

This tint delivers a natural, dewy finish with buildable sheer-to-medium coverage so skin looks like skin but more even. It blurs minor imperfections and redness while still allowing freckles and natural skin texture to show through.

• Sheer-to-medium, buildable coverage
• Fresh, luminous finish that’s not oily
• Minimizes appearance of pores and fine lines visually
• Formosa ST4: light with warm undertones

Will this formula work for sensitive or acne-prone skin?

The product is formulated to be non-comedogenic, fragrance-free and dermatologist-tested, making it suitable for many sensitive or breakout-prone skin types. It avoids silicone, talc and gluten, relying on gentle, clean ingredients that aim to hydrate without clogging pores.

• Non-comedogenic and fragrance-free
• Dermatologist-tested and vegan
• No silicone, talc or gluten in the formulation
• Lightweight feel reduces likelihood of pore congestion

How should I apply the tint for best results and sun protection?

Dispense a small pump and smooth across face with fingers, brush or sponge, blending outward for even coverage. Reapply sunscreen every two hours when exposed to direct sunlight; because it’s a mineral SPF, layering and reapplication provide the best ongoing protection.

• Start with one pump; build where more coverage is needed
• Blend with fingers or a damp sponge for seamless finish
• Reapply mineral SPF every two hours for sustained protection
• Use additional sunscreen beneath if you need full sunscreen replacement

Who this is for: If you want a multitasking product that smooths and hydrates skin while offering mineral SPF and natural-looking coverage, ILIA Super Serum Skin Tint SPF 40 in Formosa ST4 is a strong choice. It suits people who prefer clean, lightweight cosmetics, those with normal to dry or combination skin seeking glow and subtle camouflage, and anyone looking to streamline their beauty routine with a cruelty-free, vegan option.
