The "Water-Light" Innovation

Skin Aqua (by Rohto Mentholatum) is famous for its "Solarex-3" technology, which provides photostable protection that doesn't break down easily under UV exposure. The "Gel" designation is slightly deceptive—it behaves more like a refreshing essence. Once applied, it "bursts" into a watery fluid that disappears into the skin, leaving behind a natural, healthy glow rather than a greasy film.

Key Features & Benefits:

Maximum PA++++ Protection: Offers the highest level of defense against UVA rays, which are responsible for deep-seated skin aging and pigmentation.
Quadruple Hyaluronic Acid: Infused with specialized Hyaluronic Acid molecules (including Nano and Super versions) that hydrate different layers of the skin.
Sweat & Water Resistant: Designed to stay effective even if you perspire, though it is easily removed with a standard cleanser like the Neutrogena Hydro Boost Water Gel.
Zero White Cast: Completely transparent on all skin tones, making it perfect for layering under the W7 12 Hour HD Foundation without altering the shade.
Large 110g Value Size: Most facial sunscreens come in 30ml or 50ml; this 110g bottle offers significantly more product, making it economical for daily use on the face, neck, and arms.

How to Use for All-Day Defense:

Prep: Apply as the final step of your morning skincare, following the Simple Replenishing Rich Moisturiser.
Amount: Use about a 1/4 teaspoon for the face alone. Because it is a 110g bottle, don't be afraid to apply a generous amount to your neck and chest as well.
Application: Spread evenly and allow it to "dry down" for about 60 seconds. It creates a smooth, non-tacky base.
Makeup Synergy: Because it is so hydrating, it prevents your Maybelline Fit Me Foundation from clinging to dry patches or looking "cakey" by mid-day.
Reapplication: If you are outdoors, its lightweight nature makes it easy to layer another coat without feeling "heavy."

Pro-Tip: If you are treating dark spots with the Anua Niacinamide 10% + TXA 4% Serum, this sunscreen is your best friend. Its high PA++++ rating ensures that the sun doesn't "re-darken" the spots you are trying to fade, while the Hyaluronic Acid keeps your skin barrier plump and resilient.
