Skin-Nomad's Take — At a Glance
- Low-pH cleansing foam with eight Hyaluronic Acid types for all skin
- Amino acids smooth texture; barrier-safe twice-daily formula
- Fragrance-free and EWG verified, including for sensitive skin
ISNTREE is a Seoul-based South Korean brand founded in 2014, known for building products around a single well-evidenced active at a meaningful concentration. The Hyaluronic Acid Low-pH Cleansing Foam is exactly what it describes: a gentle foaming cleanser that maintains a low, skin-compatible pH while delivering eight types of Hyaluronic Acid and a full amino acid complex within the cleansing formula itself. This is not a standard foam cleanser with added marketing claims — it is a formula designed around the understanding that the cleansing step should preserve barrier integrity and actively support skin hydration, not simply remove impurities.
Key Benefits
The formula delivers thorough daily cleansing alongside meaningful hydration and skin texture improvement through an eight-type Hyaluronic Acid system at a barrier-compatible low pH.
- Eight-Type Hyaluronic Acid System for Hydration During Cleansing: Sodium Hyaluronate, Hydrolysed Hyaluronic Acid, Potassium Hyaluronate, and five additional Hyaluronic Acid variants of different molecular weights provide hydration to multiple skin depths simultaneously — even within a rinse-off formula. This means the cleansing step actively contributes to skin moisture retention rather than depleting it, addressing one of the most common complaints about twice-daily cleansing.
- Amino Acid Complex for Skin Texture and Smoothness: Glycine, Serine, Glutamic Acid, and other skin-identical amino acids smooth the skin's surface texture and support the natural moisturising factor (NMF) that keeps the stratum corneum supple and resilient. Their inclusion gives the skin a noticeably softer, more velvety feel after cleansing that standard surfactant-only formulas cannot deliver.
- Low pH for Barrier-Compatible Cleansing: The cleanser is formulated at a low pH that is compatible with the skin's natural acid mantle, preventing the barrier disruption that conventional alkaline foaming cleansers cause with daily use. This is particularly important for those using acid exfoliants or retinoids, where barrier preservation at the cleansing step reduces the overall irritation burden.
- Mild Surfactant System for All Skin Types: Gentle, plant-derived surfactants create a soft lather that effectively removes sebum and impurities without over-stripping, making the formula appropriate for twice-daily use on all skin types including dry and sensitive.
Why Choose the ISNTREE Hyaluronic Acid Low-pH Cleansing Foam?
- Eight Hyaluronic Acid Types in a Cleanser: Including eight molecular weights of Hyaluronic Acid in a rinse-off formula is unusual and reflects ISNTREE's commitment to making the cleansing step contribute positively to skin hydration rather than neutrally or negatively.
- Amino Acids for a Functional Difference: The inclusion of skin-identical amino acids alongside the Hyaluronic Acid complex is a formulation choice that goes beyond standard gentle cleansers, delivering visible smoothness and improved texture that users notice immediately after the first few uses.
- EWG Verified and Dermatologist-Tested: Free from artificial fragrance, essential oils, alcohol, and parabens. Verified to EWG safety standards and tested for sensitive skin suitability.
Ideal For
- Skin types: All skin types, including dry, combination, normal, and sensitive skin
- Skin concerns: Daily cleansing, barrier maintenance, dehydration, post-cleanse tightness, and skin texture improvement
- Best used by: Those who want their daily cleanser to actively support hydration rather than strip it; anyone using actives who needs a barrier-safe cleansing step; those who have noticed skin tightness or roughness after cleansing with conventional foaming formulas
FAQ
Q: Can this remove waterproof makeup or SPF?
A: It effectively removes light makeup and daily impurities. For waterproof makeup or SPF, use an oil cleanser or micellar water as a first cleanse and follow with this foam cleanser as the second step in a double-cleanse routine.
Q: Will Hyaluronic Acid in a rinse-off cleanser actually hydrate my skin?
A: With eight molecular weight variants, yes. While rinse-off contact time is brief, the multiple Hyaluronic Acid types in this formula have a meaningful hydrating effect that users notice as improved post-cleanse skin feel and texture compared to standard cleansers.
Q: Is this suitable during pregnancy?
A: Yes. The formula is free from retinoids, high-percentage acids, and other ingredients flagged during pregnancy. As always, check with your midwife or GP before introducing new products.
The ISNTREE Hyaluronic Acid Low-pH Cleansing Foam is the daily cleanser for anyone who has accepted that cleansing means depleting the skin's moisture, and wants to stop accepting that.
