Take the skin testThe AESTURA A-Cica 365 Hydrating Relief Toner pH4.5 is a low-pH calming toner designed to hydrate, soothe, and rebalance sensitive or acne-prone skin. Formulated at an optimal pH of 4.5, it helps maintain the skin’s natural protective barrier while reducing redness and irritation. Powered by the A-Cica Complex and barrier-supporting ingredients, this lightweight toner delivers immediate moisture while promoting long-term skin resilience. Its refreshing, watery texture absorbs quickly without stickiness, making it ideal for layering in both morning and evening routines. The AESTURA A-Cica 365 Hydrating Relief Toner helps calm stressed skin, refine texture, and prepare the complexion for the next steps in your skincare routine.
A-Cica 365 Hydrating Relief Toner pH4.5 is a watery-light toner from Aestura, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 25 ingredients, each broken down in full below.
By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte. Hydration is handled by Butylene Glycol, Glycerin and Ethylhexylglycerin, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Ethylhexylglycerin and Sodium Hyaluronate.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, 3-o-ethyl Ascorbic Acid, Gluconolactone and Tocopherol.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Asiaticoside, Madecassoside, Niacinamide and Sodium Hyaluronate.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Lecithin and Madecassoside.
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes after cleansing, before serums. Apply to slightly damp skin so the humectants have water to hold on to.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.

Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
