Aestura THERACNE365 ACTIVE SERUM

Ingredient analysis and how the ad lines read

Read on 2026-09-24

What is this product?

A Korean acne care serum from Aestura's THERACNE 365 line, a 30 ml dropper bottle sold on the brand's own sites. The 31 entry list, identical in order in Korean and English, pairs the line's zinc chloride, dipotassium glycyrrhizate, niacinamide and salicylic acid with lactic and glycolic acid, denatured alcohol fourth, zinc PCA and centella triterpenes. No level or pH is printed. The brand reports a seven day test on 29 adults: sebum down 16.9 percent, dead skin 7.6 percent, temporary pores 34.5 percent, texture 7.1 percent and pigmentation 4.7 percent. Its Korean and international pages give different test dates, and the international page states the comparison was against its own control product. Patch, repeat application and non comedogenic tests are described without results. There is no fragrance entry, but it is not acid free and not alcohol free. No lived use reports were collected.

What makes it different?

Within its line, this serum is the entry that adds alpha hydroxy acids and alcohol: the landed toner and moisturiser share its zinc chloride, salicylic acid, licorice salt and niacinamide, but print no lactic acid, glycolic acid or denatured alcohol. Glycolic acid, sunflower seed oil, lupinus albus seed extract, menthoxypropanediol and zanthoxylum piperitum oil appear in none of the brand's 21 other records read here. The trade-offs: no active level or pH is printed, the seven day test results are modest and dated differently on the two brand pages, and the safety badges carry no results.
