Ingredient breakdown

INGREDIENTS

Sodium Hyaluronate 4,000 ppmProven

  • Benefit: Improves skin hydration by up to 96% in clinical studies
  • Molecular Weight: Medium weight for optimal penetration

  • Benefit: Supports wound healing and skin barrier repair
  • Source: Extracted from the Sea Buckthorn plant

Glycerin 4.7-7%Proven

A powerful humectant naturally present in skin. Studies show glycerin may be even more effective at hydrating than hyaluronic acid, pulling moisture deep into skin layers.

  • Safety: Comedogenic rating 0, irritancy rating 0

Frequently asked questions

FAQ

Yes, this essence is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or other ingredients typically advised to avoid during pregnancy. Hyaluronic acid is a naturally occurring substance in our bodies and does not penetrate beyond the skin's surface when applied topically. As always, consult with your healthcare provider if you have specific concerns.

Yes, this product is fungal acne safe according to ingredient analysis from SkinCarisma and other databases. It's free from oils, fatty acids, esters, polysorbates, and fermented ingredients that can feed malassezia yeast. The minimal 7-ingredient formula makes it an excellent choice for those prone to fungal acne.

Yes, this essence pairs well with most active ingredients. It's a hydrating product with no conflicting actives. Apply after cleansing and toning, before your serums. For acids (AHA/BHA), apply them first, wait a few minutes, then use this essence. For retinol, apply this essence first for hydration, then retinol. Vitamin C can be applied before or after - just wait for each layer to absorb.

This essence works for all skin types but is particularly excellent for oily, combination, sensitive, and acne-prone skin due to its lightweight, oil-free, non-comedogenic formula. Dry skin types will also benefit but may need to layer a richer moisturizer on top. The minimal ingredient list makes it ideal for sensitive and reactive skin.

You'll notice immediate hydration and softer skin right after the first application. Within 1-2 weeks of consistent use, expect improved skin texture and reduced dryness. By 3-4 weeks, many users report a visible plumping effect and reduced appearance of fine lines. Full benefits for skin barrier strengthening typically appear after 1-2 months of regular use.

Apply after cleansing and toning, before serums and moisturizers. The general rule is thinnest to thickest consistency. This essence should be step 3 in a typical routine: 1) Cleanser, 2) Toner, 3) This Essence, 4) Serum, 5) Moisturizer, 6) Sunscreen (AM). Apply to slightly damp skin for best hyaluronic acid absorption.

No, this product has a comedogenic rating of 0/5, meaning it will not clog pores. It's oil-free, fragrance-free, and formulated with only 7 non-comedogenic ingredients. It's specifically designed to be safe for acne-prone skin and has been dermatologist tested and patch tested for sensitive skin.

The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal efficacy and safety. The 100ml bottle typically lasts 3-4 months with twice-daily use (2-3 pumps per application). Store in a cool, dry place away from direct sunlight to maintain product integrity.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: The COSRX Hyaluronic Acid Hydra Power Essence is an excellent, no-fuss hydrating essence that delivers on its promises. Its standout feature is the ultra-minimal 7-ingredient formula that makes it safe for virtually everyone - including pregnant women, those with fungal acne, and sensitive skin types. While competitors may offer more sophisticated multi-weight HA formulas, COSRX's approach of "less is more" provides reliable hydration without the risk of irritation. The lightweight, oil-free texture absorbs beautifully and layers well under other products. At around $20 for 100ml, it offers solid value and proves that effective skincare doesn't need dozens of ingredients. Highly recommended as a daily hydration staple, especially for those who prioritize clean, simple formulas.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
