MEDIHEAL Collagen Glow Firming Cleanser — Mousse Raffermissante au Collagène 300 Da

At the heart of this firming foam: Vegetable hydrolyzed collagen (Hydrolyzed Collagen) with 98% purity and especially featuring an ultra-low molecular weight of 300 Daltons — much smaller than an average human pore. This micro-fragmentation allows optimal penetration beyond the skin barrier, where structural fibers need to be plumped. Result: a visible "density restored" effect after use.

Palmitoyl Pentapeptide-4 (synthetic collagen peptide): mimicking natural collagen fragments, it stimulates extracellular matrix synthesis. In synergy with Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid and Hydrolyzed Sodium Hyaluronate (three molecular weights of hyaluronic acid), the epidermis retains its moisture cushion even after rinsing.

Another strategic duo: LHA (lipohydroxy acid) and PHA (polyhydroxy acid) provide gentle surface exfoliation, releasing dead cells without stripping. Combined with Panthenol (provitamin B5) and Betaine, these exfoliants respect the balance of the hydrolipidic film.

☀️ Morning routine

1. Moisten your face with lukewarm water, take a small amount of foam
2. Add a few drops of water to the palm to create a light pink airy foam
3. Massage with upward circular motions, focus on the T-zone without rubbing
4. Rinse with lukewarm water, finish with a splash of cool water to close the pores
5. Follow with your toner, then your usual serum

🌙 Evening routine

1. If you wear makeup, start with a double cleanse using a cleansing oil
2. Then apply this foaming cleanser as the second step of cleansing
3. Leave on the face for 20 seconds to let the peptides work
4. Gently massage, rinse thoroughly
5. Continue with your night routine (essence, ampoule, cream)

This foaming cleanser is intended for the following profiles:

• Mature skin (30 years and older) looking for a cleanser that does more than just clean, but actively prepares the skin for subsequent anti-aging treatments
• Dehydrated skin after washing : if you usually experience tightness or immediate dryness after rinsing, this mildly alkaline pH (9.5-10.5) dissolves sebum while preserving comfort
• Dull complexion, rough texture : LHA/PHA gradually smooth the skin texture without irritation
• Normal to combination skin with early signs of sagging (less defined oval, loss of firmness)
• Layering enthusiasts wanting to optimize the absorption of active ingredients — liposomal collagen facilitates the penetration of products applied afterward

Avoid if: severe skin reaction to peptides (rare), confirmed allergy to Palmitoyl Pentapeptide-4.

From the first use : dense elastic foam that does not "collapse," immediate sensation of plump skin to the touch. No tightness after rinsing thanks to the hyaluronate trio.

After 2 weeks of daily use : noticeable improvement in sebum control (+105.34% according to clinical tests on a non-comedogenic formula), more even complexion. Skin texture refines thanks to gentle enzymatic exfoliation with LHA/PHA.

After 1 month : measurable improvement in skin elasticity (clinical data show +102.88% firmness and +177.73% radiance after a single use in vitro test — cumulative results expected with prolonged use). The facial contour appears reshaped, skin looks firmer without being dried out.

This cleanser acts as a structural primer: it does not replace an anti-aging serum but prepares the skin’s architecture to maximize its benefits.

Can collagen in a cleanser really penetrate the skin, since it is rinsed off?

Yes, thanks to the ultra-low molecular weight of 300 Daltons — well below the skin permeability threshold (500 Da). Even with brief contact (30-60 seconds), the liposomal system encapsulates plant collagen fragments and promotes their delivery into the superficial layers of the epidermis before rinsing. It’s obviously not equivalent to a leave-on serum, but sufficient to initiate a structural “boost” effect.

Why an alkaline pH (9.5-10.5) when the skin is naturally acidic (pH 5.5)?

This slightly alkaline pH is strategic to effectively emulsify sebum and oily impurities without using harsh sulfate surfactants. The formula compensates with a massive supply of moisturizing agents (Panthenol, Betaine, Glycerin), and the protective film naturally rebuilds within 20-30 minutes. It’s a scientific compromise validated by the primary irritation test (index 0.00 — hypoallergenic).

What’s the difference compared to other cleansers in the MEDIHEAL range?

The Collagen Glow Firming Cleanser is the brand’s only cleanser focused on skin density and firming. Unlike classic moisturizing formulas (N.M.F Line), it includes collagen peptides + gentle exfoliants (LHA/PHA) for a preventive anti-aging action starting at the cleansing step. If you just want to cleanse without tightness, favor the N.M.F versions. If you aim for firmness + radiance, this is the one.

How long does a 120 ml bottle last with daily use?

About 2 to 3 months (morning + evening use), since a small amount (0.5-1 ml) is enough to generate abundant foam thanks to high-density microbubbles. The yield is excellent: the elastic bubbles cover the entire face without needing overdosing.

Can I use it if I have a retinol or acid (AHA/BHA) routine in the evening?

Absolutely. This cleanser contains LHA/PHA at a gentle concentration (non-irritating even for sensitive skin). You can use it as the first step even on evenings when you apply retinol or more concentrated acids afterward. Just be sure to rinse well to avoid any interaction between actives, and wait 5-10 minutes before applying your treatment.

Is the fragrance strong? Does it contain allergens?

The formula contains Fragrance (listed at the end of the INCI list), but the scent remains subtle and fleeting — it does not linger after rinsing. If you are very sensitive to synthetic fragrances, do a patch test on your forearm 24 hours before full use. No major allergens (essential oils, denatured alcohol) have been reported in the composition.

Founded over 10 years ago in Seoul, MEDIHEAL has established itself as the number one fabric mask brand in Korea — with five masks sold every second worldwide. Born in a medical academic environment, the brand develops its formulas in collaboration with renowned dermatologists and estheticians, in an independent R&D center opened in 2017.

Initially positioned with ultra-affordable sheet masks sold at Olive Young, MEDIHEAL quickly expanded its expertise to complete ranges (ampoules, toner pads, cleansers) while maintaining its DNA: all-in-one, scientifically validated solutions at fair prices. The historic collaboration with the BTS group propelled the brand internationally, solidifying its reputation as a specialist in "power-packed" masks.

Today, MEDIHEAL offers innovations like this 300 Da collagen cleanser, proof that the brand no longer limits its expertise to masks but rethinks every step of the routine with a rigorous dermocosmetic approach.
