ASCE+ Exomist-S Toner

ASCE+ Exomist-S Toner is a regenerating, ultra-hydrating exosome toner-mist by ExoCoBio, built on rose stem cell exosomes, a peptide complex with Copper Tripeptide-1 and Nonapeptide, amino acids, trehalose and hydrating oils, designed to support deep cellular repair, restore the skin barrier and deliver intense hydration in a light, fast-absorbing mist

ASCE+ Exomist-S is the regenerating facial toner-mist from the ASCE+ exosome range by ExoCoBio, the Korean biotechnology company that pioneered exosome-based skincare. It is a dermocosmetic care product conceived as a spray toner that combines rose stem cell exosomes with a peptide complex, amino acids, trehalose and light hydrating oils. The formula is focused on deep cellular repair and restoring the skin barrier, making it a comforting, ultra-hydrating step for skin that is stressed, dehydrated or recovering after a professional treatment. Applied as a fine mist with a delicate rose scent, it prepares and soothes the skin before the rest of the routine.

Rose exosome technology

Rose stem cell exosomes are the heart of this toner. Exosomes are tiny vesicles that cells release to carry signals between one another, and in skincare they are valued for their ability to support the skin's own repair and renewal processes. ExoCoBio is recognised as a pioneer of exosome cosmetics, and its ASCE+ range brings this technology into targeted care. In Exomist-S, the rose-derived exosomes are the signal that helps drive deep cellular repair, so the skin looks calmer, healthier and more resilient with regular use.

A fresh two-part activation system

Exomist-S is a two-component product designed to keep the actives fresh. The lyophilised (freeze-dried) exosome powder in the capsule is mixed with the activator solution just before use, producing a light emulsion with a fine rose scent. Freeze-drying the exosomes until the moment of use helps preserve their activity, so the mist is at its most potent when you start using it. Once mixed, the product is meant to be used within 21 days, which keeps every application fresh and effective.

Barrier repair and skin regeneration

The core purpose of Exomist-S is deep cellular repair and restoring the skin barrier. A healthy barrier is what keeps moisture in and irritants out, and it is often weakened by dryness, sensitivity or professional procedures. By combining the regenerating signal of the exosomes with soothing, hydrating actives, the mist helps the skin rebuild its protective barrier and recover a calmer, more comfortable feel. This makes it especially valuable for skin that feels tight, reactive or depleted.

Peptide complex - Copper Tripeptide-1 and Nonapeptide

The formula is reinforced with a peptide complex that includes Copper Tripeptide-1 and Nonapeptide, peptides recognised for supporting collagen production and helping maintain firmness. Copper Tripeptide-1 is a well-known signal peptide associated with skin renewal and support of the skin's structure, while the nonapeptide contributes to the formula's smoothing, firming character. Together they add a firming, regenerating dimension to what is primarily a soothing, hydrating mist, so the skin is not only comforted but also supported over time.

Amino acids and trehalose for lasting hydration

Exomist-S contains amino acids and trehalose, ingredients that work to maintain an optimal level of water in the upper layers of the skin and prevent dehydration. Amino acids are natural components of the skin's own moisturising system, and trehalose is a sugar prized for its ability to hold water and protect cells against moisture loss. This pairing gives the mist its ultra-hydrating character, helping the skin stay plump, supple and comfortable rather than tight and dry.

Light hydrating oils for a velvety finish

To round out the hydration, the formula includes small amounts of hydrating oils - shea butter, olive oil and squalane. These are used in measured quantities to give the mist a soft, velvety finish without a greasy or sticky feel. Squalane in particular is a lightweight, skin-friendly emollient that mimics the skin's own lipids, so it cushions and smooths the surface while keeping the texture light. The result is a mist that leaves the skin comfortable and supple rather than heavy.

Main benefits of ASCE+ Exomist-S

The key benefits are: deep cellular repair and support for the skin's barrier from rose stem cell exosomes; firming, regenerating support from the Copper Tripeptide-1 and Nonapeptide complex; intense, lasting hydration from amino acids and trehalose; a velvety, non-greasy finish from light hydrating oils; and a fresh, freeze-dried formula activated just before use. It is designed to leave stressed, dehydrated or recovering skin looking calmer, more hydrated and more resilient.

Who it is for

Exomist-S suits anyone who wants an exosome-powered, barrier-repairing and ultra-hydrating toner. It is particularly valuable for skin that feels dehydrated, tight, sensitive or compromised, and for skin that is recovering after professional dermatological or aesthetic procedures, when calming and barrier support matter most. Because it focuses on repair and hydration rather than exfoliation, it is a gentle, comforting choice that fits into most routines and skin types looking for regeneration and comfort.

How to use

Before first use, mix the freeze-dried exosome powder from the capsule with the activator solution to form the light emulsion. On clean skin, mist Exomist-S evenly over the face as your toner step, or apply to the areas that need soothing and hydration, and let it absorb. Follow with a serum and moisturiser as usual. It can be used morning and evening, and is a comforting step after professional treatments. For best results, use the mixed product within 21 days, and in the morning finish the routine with a broad-spectrum SPF as good daily practice.

The toner-mist step in a routine

As a toner-mist, Exomist-S sits early in the routine, right after cleansing, where it hydrates and preps the skin so the following steps absorb better. Its light, fast-absorbing texture layers easily under serums and creams, and its mist format makes it convenient for a quick soothing, hydrating refresh whenever the skin feels tight or stressed. This flexibility lets it work both as a daily toner and as a targeted comfort step during recovery periods.
