๐ฌ Ingredient Breakdown
๐ง Hyaluronic Acid Complex ~1.5% Proven
A powerful humectant naturally found in skin that can hold up to 1,000 times its weight in water. This formula uses both hydrolyzed sodium hyaluronate (smaller molecules for deeper penetration) and sodium hyaluronate (larger molecules for surface hydration).
- Clinical Evidence: Extensively studied for skin hydration with proven efficacy
- Source: Derived from wheat fermentation (plant-based)
- Mechanism: Attracts and binds water to skin surface and upper layers
๐ฌ Polyglutamic Acid (PGA) ~0.5% Promising
A next-generation humectant derived from fermented soybeans that can hold up to 5,000 times its weight in water - 5x more than hyaluronic acid. Works synergistically with HA to prevent moisture loss.
- Clinical Evidence: Studies show enhanced moisture retention when combined with HA
- Source: Derived from corn and soy fermentation (natural origin)
- Mechanism: Forms a film on skin that locks in moisture and prevents transepidermal water loss
๐ฟ Glycerin & Diglycerin ~5-8% Proven
Classic humectants that draw moisture to the skin. A 2016 study found glycerin to be more effective as a humectant than AHAs and even hyaluronic acid in some applications.
- Clinical Evidence: Extensively proven for hydration and barrier support
- Source: Plant-derived (typically from vegetable oils)
- Mechanism: Low molecular weight allows deep penetration and water attraction

๐ Where It Fits in Your Routine

๐ How to Use
Cleanse Your Face
Start with clean, freshly washed skin. Pat your face until it's slightly damp - not completely dry.
Dispense 2-3 Drops
Apply a few drops of serum to your fingertips. A little goes a long way with this concentrated formula.
Gently Pat & Press
Spread evenly across face and neck using gentle patting motions. Massage until fully absorbed (about 30 seconds).

โ Frequently Asked Questions
Yes! This serum is completely safe for pregnancy and breastfeeding. It contains only pregnancy-approved ingredients like hyaluronic acid, polyglutamic acid, and glycerin. There are no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or any other ingredients of concern during pregnancy. Both major ingredient types (HA and PGA) are widely considered safe by dermatologists for expectant and nursing mothers.
Yes! This serum is verified fungal acne safe. The formula is free from fatty acids, esters, ferments, polysorbates, and oils that feed malassezia yeast. It relies entirely on humectant-based hydration (hyaluronic acid, polyglutamic acid, glycerin) which do not promote fungal growth. SkinSort and other ingredient analyzers confirm this product is safe for those with fungal acne.
Yes, this serum pairs beautifully with most actives! Apply the hydrating serum first to damp skin, let it absorb, then follow with your retinol, vitamin C, or exfoliating acids. The hydration actually helps buffer potential irritation from stronger actives. For AHAs/BHAs, you can apply the serum after the acid has absorbed. Just avoid layering too many actives at once - stick to 1-2 treatments per routine.
This serum is excellent for ALL skin types, including sensitive and acne-prone skin. It's particularly beneficial for: dry/dehydrated skin (intense moisture), combination skin (lightweight, won't overwhelm oily areas), sensitive skin (minimal ingredients, fragrance-free), and acne-prone skin (non-comedogenic, fungal acne safe). Even oily skin types can benefit from this lightweight hydration.
You'll notice immediate hydration and plumping right after application. Clinical studies show 48% increased hydration at 8 hours. For longer-term benefits like reduced fine lines and improved skin texture, consistent use for 28 days shows a 17% decrease in dehydration lines. Maximum benefits are typically seen with 4-8 weeks of twice-daily use.
Apply after cleansing and toning, before heavier serums, treatments, or moisturizer. The general rule is thinnest to thickest consistency. This serum should go: Cleanser โ Toner โ THIS SERUM โ Treatment serums (retinol, vitamin C) โ Moisturizer โ Sunscreen (AM). Apply to slightly damp skin for best absorption, then seal with moisturizer.
No, this serum is non-comedogenic with a very low comedogenic rating of 1/5. The formula is oil-free and contains no pore-clogging ingredients. All the humectants used (hyaluronic acid, polyglutamic acid, glycerin) are water-based and attract moisture without blocking pores. It's safe for acne-prone skin and has been clinically tested for all skin types.
The serum has a PAO (Period After Opening) of 12 months. With twice-daily use on face and neck, the 30ml bottle typically lasts 2-3 months. Store in a cool, dry place away from direct sunlight. The glass dropper bottle helps protect the formula from light degradation. No refrigeration needed, but avoid extreme temperatures.
Verdict: The Sephora Collection Hydrating Serum delivers impressive hydration at an accessible price point. Its clinically-proven formula combining hyaluronic acid with polyglutamic acid provides effective dual-action moisture that lasts 24 hours. The minimal ingredient list (just 16), fragrance-free formula, and clean beauty credentials make it an excellent choice for sensitive skin, pregnant individuals, and those with fungal acne concerns. While it won't replace targeted anti-aging treatments, as a foundational hydrating serum it offers exceptional value with 97% natural-origin ingredients and eco-friendly packaging. A solid choice for anyone seeking straightforward, effective hydration.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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 ยซpromisesยป 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.
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.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
