In this video, board‑certified dermatologist Dr. Jane Yoo reviews two products from Shiseido’s Japanese IHADA sensitive‑skin line. She first explains the IHADA Tone Up UV Milk (Clear Beige SPF 50+ PA++++), a lightly tinted sunscreen that also works as a makeup primer. She details its filter system—octinoxate, ensulazol, Uvinul A+, titanium dioxide, and iron oxides—highlighting UVB, UVA, visible‑light, and high‑energy blue‑light protection, and notes the inclusion of Trans‑Ammic Acid, a brightening agent that reduces melanin production. Dr. Yoo emphasizes its convenience for a streamlined morning routine and its relevance for hyperpigmentation management. Next, she introduces the IHADA Aller Screen X spray, an allergen‑barrier mist that creates an invisible ionic layer using Shiseido’s Particulate Absorption Prevention Technology. The mist reduces static electricity on the skin, limiting adherence of airborne particles such as pollen and certain viruses, and can be applied over makeup or a mask. It is paraben‑free, contains hot‑spring water, and is suitable for ages six and up. Dr. Yoo cautions that the product does not guarantee complete protection and should be used alongside other protective habits. Throughout, she frames IHADA’s approach as a broader view of environmental skin exposure, integrating UV, visible light, and particulate protection.

Hi everyone, I'm Dr. Jane Yoo, board-certified dermatologist and Mohs surgeon. Today I want to highlight two products from Ihada, Shiseido's sensitive skin line from Japan. Ihada is a line that takes a broader approach to skin protection, considering UV exposure and also environmental factors like pollen and particulate matter. First is the Ihada Tone Up UV Milk in Clear Beige SPF 50+ PA++++. This is a lightly tinted sunscreen that also functions as a makeup primer, giving a more even finish right out of the tube. The filter system combines octinoxate and ensulazol for UVB protection, Uvinul A+ for UVA, and titanium dioxide, which covers both UVB and part of the UVA range. Iron oxides are also included, which extend protection into the visible light and high-energy blue light ranges. This is especially relevant for anyone managing hyperpigmentation since visible light can contribute to melanin production. On the active ingredient side, Trans-Ammic Acid, an ingredient developed in Japan, helps reduce excess melanin production and can gradually improve the appearance of dark spots. So in just one step, this product provides sun protection, some visible light coverage, a subtle tint, a primer effect, and a brightening ingredient. So for people who prefer a more streamlined routine in the morning, this can simplify a few steps. The second product addresses something many people deal with, including myself, especially during allergy season. The I'HAADA Aller Screen X is designed as an allergen barrier. When sprayed before going outside, it forms an invisible ionic layer over the skin and hair using Shiseido's Particulate Absorption Prevention Technology. This layer works by reducing static electricity on the skin's surface, which is one of the ways airborne particles like pollen and certain viruses can adhere. The mist applies evenly and can be used over makeup and can also be used while wearing a mask. It is suitable for ages 6 and up is paraben-free, and includes natural hot spring water in the formula. However, it is important to note that this type of product is not a guarantee. It does not completely block particles or prevent all allergic reactions, and it works best alongside other measures like hand washing and general protective habits. As an additional layer during high pollen season or in more polluted environments, This is an interesting approach. IHADA as a line takes a broader view of environmental skin exposure, and these two products are examples of that perspective.
