About RX Hyaluronic Acid 2% Hydrating Serum

Overview

RX Hyaluronic Acid 2% Hydrating Serum is a watery-light serum from Heimish, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 18 ingredients, each broken down in full below.

Texture and finish

By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte. Hydration is handled by Propanediol, Butylene Glycol and Sodium Hyaluronate, humectants that pull water into the upper layers of skin rather than sealing it there.

What the formula does

Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Butylene Glycol, Sodium Hyaluronate and Panthenol.

Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Ectoin, Sodium Hyaluronate and Sodium Hyaluronate Crosspolymer.

Who it suits

On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry, Combination (dry) and Balanced 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.

What it does not target

The formula contributes little or nothing on antioxidant protection, oil control, brightening and tone and cell renewal. 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.

What is not in it

Reading the full list, the formula is essential-oil-free, no drying alcohol, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, worth knowing if your skin reacts to any of them.

Where it fits in a routine

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.

Where it fits in a routine

Morning Evening
  1. Cleanse
  2. Toning
  3. Treat
  4. Moisturise
  5. Protect

This product is the "Treat" step.

  • 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.

Safety and suitability

Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.

Pregnancy and breastfeeding
Nothing in this formula is on the standard pregnancy-caution list. That is not clearance — ask your doctor about anything you use daily.
Fungal acne (malassezia)
1 ingredient could feed malassezia: Glycereth-25 PCA Isostearate. That is about the yeast's food supply, not a prediction that you will break out.
Sensitive and reactive skin
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.
