Frequently asked questions
FAQYes, Medik8 confirms this product does not contain any ingredients to avoid during pregnancy or breastfeeding. It's free from retinoids, salicylic acid, hydroquinone, and chemical sunscreens. However, always consult your doctor or midwife before using any skincare products during pregnancy.
Yes, this serum is fungal acne safe. It's free from fatty acids, oils, esters, polysorbates, and fermented ingredients that feed malassezia yeast. Multiple ingredient analyzers confirm it contains zero fungal acne triggers.
Yes, Hydr8 B5 Intense pairs excellently with all these actives. In fact, Medik8 recommends using it with their Crystal Retinal in the evening for enhanced results. Apply Hydr8 B5 Intense first as a hydrating base, then layer your treatment actives on top. The hydration helps buffer potential irritation from retinol and acids.
This serum excels for dehydrated and dry skin types, but works well for all skin types including oily, combination, sensitive, and acne-prone. It's specifically designed for skin in need of "intense hydration boost" versus the regular Hydr8 B5 for daily maintenance.
Instant hydration is noticeable immediately after application. Clinical studies show visible smoothing and plumping results within 24 hours. After 4 weeks of consistent use, participants showed significant improvement in skin hydration, firmness, and fine line reduction.
Apply after cleansing (and toning if you use toner), but before heavier serums and moisturizers. The order is: Cleanser → Toner → Hydr8 B5 Intense → Treatment Serums (Vitamin C AM, Retinal PM) → Moisturizer → Sunscreen (AM). Apply to damp skin for enhanced absorption.
No, this serum has a comedogenic rating of 0/5. It's completely oil-free and non-comedogenic. All key ingredients (hyaluronic acid, panthenol, glycerin) have 0 comedogenicity ratings. It's safe for acne-prone skin and won't clog pores.
The product has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight. If you use the recommended 6 drops twice daily, a 30ml bottle typically lasts 2-3 months.
Hydr8 B5 Intense is the "supercharged" version with added Natural Moisturizing Factors (NMFs), Saskatoon berry antioxidants, and a triple-action hydration booster. The original Hydr8 B5 is simpler with just multi-weight HA and B5 - great for daily maintenance of normal/sensitive skin. Choose Intense for dehydrated skin needing extra help.
Verdict: Medik8 Hydr8 B5 Intense is a premium, clinically-proven hydrating serum that delivers on its promises. The sophisticated formula with multi-weight hyaluronic acid, NMFs, and antioxidants goes beyond basic hydration to truly transform dehydrated skin. While the price is steep compared to budget alternatives like The Ordinary, the superior texture, clinical backing, and comprehensive ingredient list justify the investment for those who can afford it. Ideal for retinol users, sensitive skin types, and anyone serious about combating dehydration. A true holy grail hydrator for those willing to splurge.
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.
