Budget-friendly alternatives (dupes)
DUPESUses 5D hyaluronic acid instead of deep sea water. Equally lightweight and hydrating. Contains panthenol and allantoin for soothing. Slightly thicker gel texture. Also fungal acne safe.
Uses 96% snail mucin for hydration and repair. Thicker, more viscous texture. Better for scar healing and skin repair. Not vegan. Larger 100ml size for similar price.
Also uses Ulleungdo deep sea water (72 minerals). More of a toner than serum - thinner consistency. Contains mild exfoliating properties. Great for toner step but different product category.
Focuses on multiple weights of hyaluronic acid. More watery toner consistency. Good hydration but lacks the mineral-rich deep sea water benefits and peptides.

Frequently asked questions
FAQYes, this serum is completely safe for pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or any other ingredients restricted during pregnancy. The formula is gentle and focuses on hydration with mineral-rich deep sea water and plant-based ingredients. It has been reviewed and approved by pregnancy-safe skincare experts.
Yes, this serum is verified fungal acne safe. It's free from fermented ingredients, problematic fatty acids, esters, polysorbates, and oils that can feed malassezia yeast. The formula has been analyzed by fungal acne databases like SkinSort and confirmed safe for those prone to fungal acne. It's actually the top-rated fungal acne safe serum from PURITO.
Yes, this serum is compatible with all major active ingredients. It contains no conflicting actives and can be safely layered with retinol, vitamin C, AHAs, BHAs, niacinamide, and other treatments. Apply this hydrating serum after water-based serums and before oils or creams. Its hydrating properties can actually help buffer potential irritation from stronger actives.
This serum is excellent for oily, combination, sensitive, and acne-prone skin types due to its lightweight, non-greasy formula. It's also good for dry skin when layered or used with a heavier moisturizer. The formula is particularly well-suited for those who find traditional hyaluronic acid serums too sticky or those living in humid climates who want hydration without heaviness.
You'll feel immediate hydration upon first application - skin feels refreshed and dewy within seconds. Visible improvements in skin texture typically appear within 1-2 weeks of consistent use. Enhanced skin barrier function and improved moisture retention develop over 3-4 weeks. For cumulative benefits like plumping and sustained hydration, expect 6-8 weeks of regular use.
Apply this serum as step 3 in your routine: after cleansing and toning, but before heavier serums, oils, moisturizers, and sunscreen. The thin, watery texture should go on before thicker products following the thin-to-thick layering rule. For best absorption, apply to slightly damp skin. Use both morning and evening for optimal results.
No, this serum has a comedogenic rating of 0/5, meaning it will not clog pores. The formula is oil-free, non-comedogenic, and specifically designed to be safe for acne-prone skin. It contains no pore-clogging ingredients and is lightweight enough to absorb completely without leaving residue that could trap bacteria or sebum.
The serum has a PAO (Period After Opening) of 12 months. Once opened, use within one year for best results. The hygienic pump packaging helps preserve the formula by minimizing air exposure and contamination. Store in a cool, dry place away from direct sunlight. The 60ml bottle typically lasts 2-3 months with twice-daily use.
Verdict: The PURITO Hydro Wave Deep Sea Serum is an exceptional lightweight hydrating serum that delivers on its promises without irritation or heaviness. Its unique 66% Gangwondo deep sea water formula provides mineral-rich hydration that feels refreshing rather than sticky - perfect for oily, combination, and sensitive skin types. The fungal acne safe and pregnancy safe credentials make it a rare find for those with specific safety requirements. While very dry skin types may need to layer this with heavier products, for most people this serum offers an ideal balance of effective hydration, clean ingredients, and sensorial pleasure. The addition of peptides provides bonus anti-aging benefits beyond basic hydration. At its price point with the doubled 60ml size, it offers excellent value for a well-formulated K-beauty serum.
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.
