โ“ Frequently Asked Questions

Yes! This serum is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Hyaluronic acid is a naturally occurring substance in the body and topical application does not significantly enter the bloodstream. However, always consult your healthcare provider if you have specific concerns.

No, this serum is NOT fungal acne safe. It contains several ingredients that can feed malassezia yeast, including isohexadecane, PEG-40 hydrogenated castor oil, and PPG-26-buteth-26. If you're prone to fungal acne, consider alternatives like The Ordinary HA 2% + B5 or COSRX Hyaluronic Acid 3% Serum which are FA-safe.

Yes! Hyaluronic acid is compatible with most active ingredients. It actually pairs well with retinol and exfoliating acids as it helps counteract dryness these actives can cause. Apply this serum before retinol to buffer and hydrate, or after vitamin C to boost moisture. When using AHA/BHA, apply this serum after the acid has absorbed to replenish hydration.

This serum is excellent for dry, dehydrated, combination, and mature skin types. It works well for normal skin too. Oily skin types can use it but may find the dewy finish too rich - apply sparingly. Sensitive skin should patch test first due to the fragrance content. NOT recommended for fungal acne-prone skin.

Immediate: Instant hydration and dewy plumpness. 1-2 weeks: Improved skin texture, fewer dry patches. 4 weeks: Visible reduction in fine lines, more radiant complexion. 6-8 weeks: Strengthened moisture barrier with long-term benefits. For best results, use consistently morning and evening.

Apply after cleansing and toning, before heavier serums, essences, and moisturizers. The rule is thinnest to thickest consistency. Apply to slightly damp skin for best absorption. Follow with moisturizer to seal in hydration, and sunscreen in the morning. Can be used both AM and PM.

This serum has a low comedogenic rating of 1/5, meaning it's unlikely to clog pores for most people. The lightweight, water-based formula absorbs well without leaving heavy residue. However, individual reactions vary - if you're acne-prone, patch test first. Note: while it won't cause regular acne, it's NOT safe for fungal acne.

The PAO (Period After Opening) is 12 months. Store in a cool, dry place away from direct sunlight. The glass bottle with pump dispenser helps maintain product integrity by limiting air exposure. Most users find the 40ml bottle lasts 2-3 months with twice-daily use, so you should use it well before it expires.

โ˜…โ˜…โ˜…โ˜…โ˜†
4.2 out of 5

Verdict: It's Skin Hyaluronic Acid Moisture Serum delivers solid K-beauty hydration at an accessible price point. The formula, developed with Seoul University dermatologists, combines low-molecular hyaluronic acid with antioxidant-rich botanicals like acerola and blueberry for comprehensive moisture care. It's pregnancy-safe, has low comedogenic potential, and provides visible plumping results. However, it's NOT suitable for fungal acne-prone skin and contains fragrance, which may not suit everyone. If you're looking for a no-frills, FA-safe option, The Ordinary offers better value. But for those wanting botanical benefits alongside hydration in a luxurious texture, this K-beauty gem delivers.

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 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.

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.
