Frequently asked questions
FAQYes, this serum is considered safe for use during pregnancy and breastfeeding. It does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreens - the main ingredients to avoid during pregnancy. The formula relies on gentle hydrating ingredients like green tea, hyaluronic acid, and niacinamide that are safe for expecting and nursing mothers.
No, this serum is NOT fungal acne safe. It contains several potential malassezia triggers including Sorbitan Olivate (olive oil-derived), Sorbitan Isostearate (isostearic acid base), Lactobacillus Ferment Lysate (fermented ingredient), and Camellia Sinensis Seed Oil. If you have fungal acne, consider alternatives like COSRX Snail Mucin Essence or Hada Labo Premium Lotion.
Yes, this serum layers well with most active ingredients. It's a hydrating serum that can help buffer and soothe skin when using stronger actives. Apply this serum first, let it absorb, then follow with your retinol or vitamin C. For AHA/BHA, apply acids first on clean skin, wait, then follow with this serum to hydrate. The niacinamide content is compatible with vitamin C despite old myths.
This serum works best for oily, combination, and normal skin types seeking lightweight hydration. The fast-absorbing gel texture is excellent for oily skin that needs moisture without greasiness. Dry skin types may need to layer with a richer moisturizer on top. Those with fungal acne should avoid this product due to trigger ingredients.
You'll notice immediate hydration and plumpness right after first use. Within 1 week, skin texture improves and feels smoother. Clinical studies show 71% hydration boost after one week of use. Full benefits including improved radiance and barrier strength typically appear after 2-4 weeks of consistent AM/PM use. 96% of users reported stronger moisture barrier after continued use.
Apply after cleansing and toning, before heavier products like moisturizer and sunscreen. The order is: Cleanser → Toner → THIS SERUM → Essence (if using) → Moisturizer → Eye Cream → SPF (AM). For maximum absorption, apply to slightly damp skin and pat gently rather than rubbing. Use 2-3 pumps for face and neck, morning and night.
This serum has a low comedogenic rating of 1/5 and has been non-comedogenic tested by the brand. Most users find it doesn't clog pores due to its lightweight, fast-absorbing formula. However, individual reactions vary. Those with acne-prone skin should patch test first. Note that while it's unlikely to cause regular acne, it can trigger fungal acne due to specific ingredients.
The PAO (Period After Opening) is 12 months. The 80ml bottle typically lasts 4-6 months with twice-daily use (2-3 pumps per application). Store in a cool, dry place away from direct sunlight. The pump dispenser helps maintain product freshness and hygiene. Innisfree also offers refill pouches to reduce waste and save money on repurchases.
Verdict: The Innisfree Green Tea Seed Intensive Hydrating Serum is a solid K-beauty hydrating serum with clinically-proven 72-hour moisture and beneficial ingredients like 5 types of hyaluronic acid, niacinamide, and antioxidant-rich Jeju green tea. It excels for oily and combination skin types seeking lightweight, fast-absorbing hydration without greasiness. The vegan, cruelty-free, refillable formula aligns with eco-conscious values. However, those with fungal acne should avoid it due to multiple trigger ingredients, and very dry skin types may find it insufficient alone. The presence of alcohol may not suit everyone. Overall, a reliable everyday hydrating serum at a reasonable price point, though not without limitations.
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 «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.
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.
