Ingredient breakdown
INGREDIENTS5D Hyaluronic Acid Complex 5 TypesProven
Five molecular weights of hyaluronic acid work in synergy to hydrate every layer of the skin. High-MW HA forms a protective moisture film on the surface, medium-MW HA plumps and smooths, and low-MW HA penetrates deeper to deliver hydration from within.
- Sodium Hyaluronate: Salt form of HA, excellent surface hydration and barrier protection
- Hydrolyzed Hyaluronic Acid: Low-MW HA for deeper skin penetration and elasticity
- Sodium Acetylated Hyaluronate: "Super HA" with enhanced skin adhesion and moisture retention
- Sodium Hyaluronate Crosspolymer: Cross-linked HA with 5x water-binding capacity for long-lasting hydration
- Hydrolyzed Sodium Hyaluronate: Ultra-low MW (10 kDa) for the deepest penetration and antioxidant activity
Panthenol (Pro-Vitamin B5)Proven
A powerful humectant and skin-soothing agent that attracts and binds moisture. Once absorbed, it converts to pantothenic acid (vitamin B5), supporting skin barrier repair and wound healing. One of the key soothing ingredients that made this serum famous in Korean skincare.
- Function: Humectant, skin barrier repair, anti-inflammatory
- Evidence: Extensive clinical literature supporting wound healing and moisturizing properties
AllantoinProven
A well-established soothing and skin-protecting ingredient derived from the comfrey plant (though typically synthesized for cosmetics). Calms irritation, promotes wound healing, and softens the skin. Particularly beneficial for sensitive and redness-prone complexions.
- Function: Skin-soothing, wound healing, skin softening
- Evidence: Long history of clinical use in dermatology for skin repair
Madecassoside & Madecassic AcidProven
Two active compounds derived from Centella Asiatica (cica). These centella compounds calm inflammation, promote collagen synthesis, and accelerate skin healing. They work synergistically with panthenol and allantoin to soothe and repair irritated skin.
- Function: Anti-inflammatory, collagen synthesis, wound healing
- Evidence: Extensively studied in dermatology for scar healing and skin barrier repair
Ceramide NP + CholesterolProven
Ceramides are essential lipids that make up the skin's natural moisture barrier. Ceramide NP combined with cholesterol mimics the skin's own lipid structure, helping to repair and strengthen a compromised barrier. This duo locks in the hydration delivered by the HA complex.
- Function: Barrier repair, moisture retention, lipid replenishment
- Evidence: Ceramides are a gold-standard ingredient for barrier repair, backed by decades of research
Malachite Extract TracePromising
A copper-rich mineral extract that gives this serum its distinctive pastel blue-green color (no artificial colorants are used). Provides antioxidant protection against free radical damage and environmental stressors.
- Function: Antioxidant, natural colorant, skin detoxification
- Evidence: Emerging research on mineral-based antioxidants in skincare

Where it fits in your routine
ROUTINEUse AM & PM after cleansing and toning. Apply on damp skin for maximum absorption. Always seal with a moisturizer to lock in hydration.
How to use
HOW TO USECleanse & Prep
Wash your face with a gentle cleanser. Leave skin slightly damp — hyaluronic acid works best when it can draw from surface moisture.
Dispense 3–5 Drops
Use the dropper to place 3–5 drops of serum onto your fingertips or directly onto your face. The pastel blue color is from natural malachite extract.
Spread & Pat Gently
Spread evenly across your face and neck. Gently pat with your palms to encourage absorption. The serum absorbs within about 3 seconds.
Layer (Optional) & Seal
For extra hydration, apply a second layer. Always follow with a moisturizer to seal in the moisture. In dry climates, an occlusive moisturizer is essential.
Who is it for?
WHOPerfect for you if:
- You have dehydrated skin that needs an intensive moisture boost
- Your skin feels tight, dry, or flaky — especially in winter or air-conditioned environments
- You have sensitive or irritation-prone skin and need a gentle, fragrance-free hydrator
- You want a lightweight serum that layers well under makeup without stickiness
- You are using retinol or other drying actives and need a hydration buffer
- You want affordable K-beauty with clinically tested results
Consider alternatives if:
- You need heavy anti-aging actives like retinol or peptides — this is purely a hydrator
- You have confirmed fungal acne (contains Polyglyceryl-10 Laurate)
- You prefer a single-step rich moisturizer — this serum needs to be sealed with a cream
- You live in an extremely dry climate and do not follow up with an occlusive
- You want visible brightening or pigmentation correction
Skin type compatibility
SKIN TYPESUltra-lightweight, watery texture absorbs instantly without adding shine or greasiness. Ideal for oily-dehydrated skin that needs moisture without weight.

Clinically tested non-irritating. Fragrance-free, alcohol-free formula with soothing panthenol, allantoin, and centella compounds. A top choice for reactive skin.
Low comedogenic rating (1/5) and oil-free formula. However, contains Polyglyceryl-10 Laurate which may not be suitable for fungal acne sufferers.

Frequently asked questions
FAQYes. The Torriden DIVE-IN Serum contains no retinoids, salicylic acid, hydroquinone, chemical sunscreen filters, or any other ingredients flagged as unsafe during pregnancy or breastfeeding. Its formula is built around hyaluronic acid, panthenol, allantoin, and centella compounds — all of which are considered safe for expectant and nursing mothers. As always, consult your healthcare provider if you have specific concerns.
Not entirely. The serum contains Polyglyceryl-10 Laurate, an emulsifier that may feed the Malassezia yeast responsible for fungal acne. While many acne-prone users report no issues, those with confirmed fungal acne should patch test carefully or consider alternatives like The Ordinary HA 2% + B5, which is fungal-acne safe.
Yes. This serum is a pure hydrator without any pH-dependent actives, so it pairs well with virtually all other skincare ingredients. Many users apply it as a hydration buffer before or after retinol to reduce irritation. It also layers well with vitamin C serums, AHAs, and BHAs. Apply the serum first, let it absorb, then follow with your active.
This serum works well for all skin types but is particularly excellent for oily-dehydrated, combination, and sensitive skin. Its lightweight, watery texture absorbs quickly without leaving residue, making it ideal for those who dislike heavy or greasy products. People with very dry skin may need to layer it generously and follow with a rich cream.
Hydration is noticeable immediately — most users report plumper, dewier skin after the very first application. Consistent improvement in skin texture and softness typically appears within 1–2 weeks. More significant results like reduced dehydration lines and improved barrier function are generally seen after 4+ weeks of daily use.
Apply after cleansing and toning, before your moisturizer. In the morning routine: Cleanser → Toner → DIVE-IN Serum → Moisturizer → Sunscreen. In the evening: Cleanser → Toner → DIVE-IN Serum → (Actives if using) → Moisturizer. Always apply on damp skin for best results.
The serum has a very low comedogenic rating of 1 out of 5. It contains no heavy oils, silicones, or known pore-clogging ingredients. The lightweight, oil-free formula is designed to hydrate without causing breakouts. It is widely used by acne-prone individuals without issues, though individual results may vary.
The serum has a Period After Opening (PAO) of 12 months. At the recommended usage of 3–5 drops twice daily, a single 50ml bottle typically lasts 4–8 weeks depending on how generously you apply it. Store in a cool, dry place away from direct sunlight to maintain potency.
Verdict: The Torriden DIVE-IN Low-Molecular Hyaluronic Acid Serum delivers on its promise of deep, multi-layer hydration at a remarkably affordable price point. The 5D hyaluronic acid complex, paired with panthenol, ceramides, and centella compounds, creates a well-rounded hydrating serum that punches well above its weight class. Its almost instant absorption, zero stickiness, and fragrance-free formula make it a standout in the crowded HA serum market. The only notable drawbacks are the small bottle size and the Polyglyceryl-10 Laurate that makes it unsuitable for fungal acne sufferers. For everyone else — especially those with sensitive, dehydrated, or combination skin — this is one of the best value-for-money hydrating serums available today. There is a reason it has been the #1 serum on Korean beauty charts for years running.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.

Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.

Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
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.
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.
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

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.
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.
