π¬ Ingredient Breakdown
π§ Sodium Hyaluronate (Hyaluronic Acid) Proven
The star ingredient and salt form of hyaluronic acid that penetrates more easily into skin. A powerful humectant naturally found in the body that attracts and retains moisture in the skin's upper layers.
- Mechanism: Attracts water molecules from the environment and deeper skin layers to hydrate the surface
- Benefits: Plumps skin, reduces appearance of fine lines, improves skin elasticity
- Research: Studies show improved skin elasticity and reduced roughness in 2-8 weeks of use
π§΄ Water (Aqua) Base
Purified and filtered water serves as the base of this serum, providing the primary hydration vehicle and allowing the hyaluronic acid to work effectively.
- Function: Solvent and hydration base
- Quality: Purified and filtered for maximum purity
π‘οΈ Phenoxyethanol <1% Preservative
A gentle preservative necessary to prevent microbial growth in water-based products. Used at safe concentrations well below industry limits.
- Function: Broad-spectrum preservative against bacteria and yeast
- Safety: EWG rating of 4 (moderate) - safe at concentrations used in leave-on products
- Note: DIME Beauty conducts stability testing to ensure minimum effective concentration
πΏ Ethylhexylglycerin <1% Preservative Booster
A gentle, plant-derived preservative booster that enhances the efficacy of phenoxyethanol while also providing mild moisturizing properties.
- Function: Preservative enhancer and skin-conditioning agent
- Safety: Considered very safe and gentle; relatively new to market
- Benefit: Allows lower concentrations of primary preservative
4 ingredients

π Where It Fits in Your Routine

β Frequently Asked Questions
Yes! Hyaluronic acid is a substance naturally found in your body and is considered completely safe for use during pregnancy and breastfeeding when applied topically. This serum contains no retinoids, salicylic acid, hydroquinone, or other ingredients to avoid during pregnancy. All 4 ingredients have been reviewed by EWG scientists and deemed safe. As always, consult with your healthcare provider if you have specific concerns.
Yes! This serum is completely fungal acne safe. It contains no oils, fatty acids, esters, ferments, or polysorbates that feed Malassezia yeast. The minimal 4-ingredient formula (water, sodium hyaluronate, phenoxyethanol, ethylhexylglycerin) is free from all common fungal acne triggers. It's an excellent hydrating option for those prone to pityrosporum folliculitis.
Absolutely! Hyaluronic acid is compatible with virtually all other skincare ingredients including retinol, vitamin C, AHAs, and BHAs. In fact, HA acts as a carrier that can enhance the absorption of other products. Apply HA serum first (on damp skin), let it absorb, then follow with your active treatments. The hydration from HA can also help buffer potential irritation from strong actives.
This serum works well for all skin types including oily, dry, combination, sensitive, and acne-prone skin. It's particularly excellent for sensitive and acne-prone skin due to its minimal, non-comedogenic formula. Those with very dry skin may want to layer with a rich moisturizer or consider a formula with multiple HA molecular weights for deeper hydration.
You'll notice immediate hydration and plumping effects right after the first application. With consistent daily use, most users report improved skin texture within 1-2 weeks and enhanced elasticity by week 4. Studies show hyaluronic acid can improve skin elasticity and reduce roughness in 2-8 weeks of regular use. Long-term benefits continue to build with continued use.
Apply after cleansing (and toning, if you use one) but before heavier serums, moisturizers, and sunscreen. For best results, apply to slightly damp skin - the HA will draw in that moisture. Always follow with a moisturizer to seal in the hydration. Use morning and/or evening. Order: Cleanser β Toner β HA Serum β Treatment Serums β Moisturizer β Sunscreen (AM).
No! This serum has a comedogenic rating of 0/5. None of the four ingredients are known to clog pores. It's oil-free, lightweight, and specifically suitable for acne-prone skin. The formula is non-comedogenic and won't contribute to breakouts. It's actually an excellent choice for those with congestion-prone skin who need hydration without heaviness.
The serum has a PAO (Period After Opening) of 12 months. At the recommended usage of 3-5 drops twice daily, one 30ml bottle typically lasts 30-60 days depending on how generously you apply. Store in a cool, dry place away from direct sunlight. The preservative system (phenoxyethanol + ethylhexylglycerin) effectively prevents microbial growth throughout its shelf life.
Verdict: DIME Beauty Hyaluronic Acid Serum is an excellent choice for those who prioritize clean, minimal skincare with transparent, EWG-verified ingredients. Its ultra-simple 4-ingredient formula is ideal for sensitive skin, pregnant/nursing individuals, and those with fungal acne. While it may lack the multi-weight HA and added actives found in competitors like The Ordinary, its purity and safety profile justify the premium for clean beauty enthusiasts. Best suited for those who want a straightforward hydration booster that plays well with any routine. Always follow with moisturizer for optimal results.
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 Β«promisesΒ» 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.
