AESTURA Theracne 365 Active Serum 30ml

AESTURA Theracne 365 Active Serum: Derm-Positioned Acne Treatment

The Theracne 365 line is AESTURA's answer to medicalized acne skincare, positioned for users who want a clinical approach without jumping to prescription retinoids or oral antibiotics. This serum combines salicylic acid at a regulated low percentage with AESTURA's Acne Solution Complex, which includes centella asiatica and Cica-7 (their proprietary calming blend). The goal is to treat active breakouts while simultaneously calming the surrounding skin, which is where most drugstore acne products fail.

AESTURA is widely recommended in Korean dermatology practice as an over-the-counter adjunct to prescription treatment. This product fits cleanly into that role: it is not replacing your dermatologist's topical tretinoin, but it supports the routine with gentle daily active care. At $48 for 30ml, it is priced in the midrange for Korean dermocosmetic products.

What It Does

Salicylic acid (BHA) penetrates sebum-filled pores to dissolve the oil and dead skin plug that forms acne. Centella asiatica (madecassoside, asiaticoside) reduces inflammatory signaling around active breakouts, preventing the red-bump halo that makes acne visible. The Cica-7 complex supports barrier recovery, because acne skin is often barrier-compromised in addition to being acne-prone. The combination treats and protects simultaneously.

Who It's For

• Mild to moderate acne: Primary use case. Whiteheads, small pustules, congested pores.
• Combination-oily skin with occasional breakouts: Good daily preventive serum.
• Sensitive acne skin that cannot tolerate benzoyl peroxide: Gentler, calming approach.
• Acne in adult skin: Targets acne without the drying effect of teen-focused products.
• Post-acne redness and texture: The calming complex helps alongside the active treatment.

How to Use

Start with 3 evenings per week, working up to nightly as tolerated. Apply 3 to 4 drops to clean, dry skin after cleansing and toner. Avoid the eye area. Follow with a barrier cream (AESTURA ATOBARRIER is the brand-mate option). Do not layer with retinol in the same evening initially, space them on alternate nights. Always use SPF 30+ during the day; BHA increases sun sensitivity.

FAQ

How does this compare to Cosrx BHA Blackhead Power Liquid?

Different positioning. Cosrx BHA is pure BHA with some willow bark, cheap and effective for oily skin. AESTURA Theracne pairs BHA with calming actives and a barrier focus, targeted at more sensitive acne skin. Cosrx is better value for oily tolerant skin; AESTURA is better for sensitive or reactive acne-prone skin.

How long until I see results?

Surface texture improvement: 1 to 2 weeks. Reduction in active breakouts: 4 to 6 weeks. Post-acne mark fading: 8 to 12 weeks. BHA works continuously, so consistency beats intensity.

Can I use it with tretinoin?

Yes, but space them out. Apply AESTURA Theracne in the morning and tretinoin at night, or alternate nights. Using both in the same evening often over-irritates.

Will it purge my skin?

Mild purging (an initial worsening in the first 2 to 3 weeks) is possible as BHA clears backed-up pore content. Persistent worsening past 4 weeks means the product is not right for your skin.

Is it safe during pregnancy?

Salicylic acid at low concentrations topically is generally considered low-risk, but pregnancy skincare is always a consult-your-doctor question. Many dermatologists approve salicylic acid, but some err conservative. Confirm with your OB.
