How to use

HOW TO USE
1

Cleanse & Prep

Start with clean skin. Leave face slightly damp or mist with toner for enhanced absorption.

2

Dispense

Apply 4-5 drops to fingertips. A little goes a long way - this is enough for face and neck.

3

Apply & Massage

Gently press and pat the serum into skin. Massage until fully absorbed (about 30 seconds).

4

Seal with Moisturizer

Wait until serum is dry, then apply your moisturizer to lock in hydration and prevent transepidermal water loss.

Frequently asked questions

FAQ

Yes, this product is completely safe during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or any other ingredients on the pregnancy-avoid list. Hyaluronic acid and Panthenol are both naturally occurring in the body and pose no risk to mother or baby.

Yes, this product is fungal acne safe. The formula contains no ferments, fatty acids (like oleic acid), esters, polysorbates, or oils that feed Malassezia yeast. The clean 8-ingredient formula makes it an excellent choice for those prone to fungal acne or pityrosporum folliculitis.

Yes, hyaluronic acid pairs well with virtually all actives. It can help buffer potentially irritating ingredients like retinol, vitamin C, and acids by providing hydration. Apply HA before or after these actives (it works either way). The Panthenol in this formula adds soothing benefits that help calm skin when using strong actives.

This serum works for all skin types but is especially beneficial for dry and dehydrated skin. The oil-free, lightweight formula also makes it excellent for oily and acne-prone skin. The minimal ingredient list is ideal for sensitive skin, and it's safe for those with fungal acne. Mature skin will appreciate the fine line-plumping effects.

You'll notice immediate plumping and hydration after the first application. Improved skin texture typically becomes noticeable within 1-2 weeks of consistent use. Visible reduction in fine lines and improved overall radiance usually appears within 3-4 weeks. For barrier strengthening benefits, allow 6-8 weeks of consistent use.

Apply after cleansing and toning, but before heavier serums and moisturizers. The rule of thumb is to apply thinnest to thickest consistency. For best results, apply to damp skin to give the HA water to bind to. Always follow with a moisturizer to seal in the hydration. Can be used both morning and evening.

No, this product has a comedogenic rating of 0/5 and will not clog pores. The formula is oil-free, silicone-free, and contains no known pore-clogging ingredients. Hyaluronic acid and Panthenol both have comedogenic ratings of 0. It's safe for acne-prone and breakout-prone skin.

The product has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maximize shelf life. The glass dropper bottle helps protect the formula from contamination. If you notice any changes in color, smell, or texture, discontinue use.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: Revox B77 Hyaluronic Acid 5% delivers exceptional value with its higher-than-average HA concentration and impressively clean 8-ingredient formula. The addition of Panthenol sets it apart from basic HA serums, offering both hydration and barrier support. While it lacks the multi-molecular weight technology found in some competitors, its simplicity is also its strength—making it ideal for sensitive skin, fungal acne sufferers, and those who prefer minimalist skincare. An excellent budget-friendly choice for anyone seeking effective hydration without unnecessary additives.

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 «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.

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.

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

question
lightbulb What are Ingredients Related to Skin Type?

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.

muscle Pro Tip Alert!

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!

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.
