Take the skin testThe AESTURA Theracne 365 Active Serum is a targeted treatment designed to visibly reduce breakouts, control excess sebum, and refine uneven skin texture. Developed with dermatological expertise, this lightweight serum helps unclog pores while soothing irritation, making it ideal for acne-prone and oily skin. Its fast-absorbing, non-greasy formula delivers active care without over-drying or compromising the skin barrier.
Theracne 365 Active Serum is a lightweight serum from Aestura, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 31 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Butylene Glycol, Glycerin and Menthoxypropanediol, 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, Menthoxypropanediol and Ethylhexylglycerin.
Oil control: Moderate. Ingredients that moderate sebum or absorb shine, and here that comes from Niacinamide, Silica, Salicylic Acid and Zinc PCA.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Dipotassium Glycyrrhizate, Lactic Acid and Glycolic Acid.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Asiaticoside, Niacinamide, Dipotassium Glycyrrhizate and Madecassic Acid.
On richness alone it suits Balanced, 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 antioxidant protection and 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, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain drying alcohol, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
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.
