Take the skin test and I'll show you how suitable this product is for you.
Take the skin testThe AESTURA Regederm 365 Skin Tightening Capsule Serum is an advanced firming serum designed to visibly improve skin elasticity and deliver a lifted, tightened appearance. Featuring encapsulated active ingredients that burst upon application, this innovative formula ensures optimal delivery of skin-firming and barrier-strengthening components. Enriched with peptides and elasticity-supporting complexes, it helps smooth fine lines while enhancing skin density and resilience. Its rich yet refined texture absorbs comfortably without heaviness, providing deep nourishment alongside tightening care.
Regederm 365 Skin Tightening Capsule Serum is a cushioning serum from Aestura, a brand based in Korea. The formula is built mainly around hydration and soothing. The ingredient list runs to 49 ingredients, each broken down in full below.
By its ingredient list the formula reads as moderately cushioned — emollient enough to feel like a cream, without the heaviest occlusives near the top. It contains both silicones and oils, a combination that usually finishes smooth and slightly satin and sits well under makeup. Hydration is handled by Butylene Glycol, Propanediol and Ethylhexylglycerin, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Propanediol, Ethylhexylglycerin and Water.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Cetyl Ethylhexanoate, Lactobacillus Ferment Lysate, Niacinamide and Adenosine.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry, Combination (dry), Combination (oily) and Oily 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 cell renewal 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, no drying alcohol, paraben-free, microplastic-free and sulfate-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 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.
Drawn purely from the ingredient list
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.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Brightens and balances complexion for a more uniform appearance
Regulates sebum production to reduce shine and greasiness
Fades hyperpigmentation and evens out dark spots over time
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.

Judged by the same curated rules our routine checker uses. It reads the ingredients, not the label.
Nothing in this formula belongs to a group our rules can put in conflict, so it layers freely. Order still matters — thinnest texture first.
This product is the "Treat" step.
Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.
