Frequently asked questions
FAQYes, E45 Face Hydrating Serum is completely safe during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or other ingredients that are restricted during pregnancy. Hyaluronic acid is a naturally occurring substance in the body, and when applied topically, it does not significantly enter the bloodstream. All ingredients have been dermatologically tested and are considered safe for expectant and nursing mothers.
Yes, E45 Face Hydrating Serum is fungal acne safe. The formula is oil-free and does not contain fatty acids, esters, fermented ingredients, or polysorbates that can feed malassezia yeast. Ingredients like hyaluronic acid, glycerin, and the algae extracts are all safe for those dealing with fungal acne or pityrosporum folliculitis. This has been verified by multiple ingredient analysis databases.
Yes, E45 Face Hydrating Serum pairs well with most active ingredients. Hyaluronic acid is hydrating and non-irritating, making it an excellent partner for potentially irritating actives like retinol or acids. For best results: apply this serum first to hydrate skin, then follow with your actives. When using with vitamin C, apply the serum on slightly damp skin, let absorb, then apply vitamin C. For retinol or acids, the serum helps buffer potential dryness and irritation.
E45 Face Hydrating Serum is specifically formulated for dry and sensitive skin, but works well for all skin types. It's especially beneficial for: dry or dehydrated skin needing intense moisture, sensitive or eczema-prone skin requiring gentle formulas, combination skin that needs hydration without oiliness, and acne-prone skin that's been stripped by treatments. The lightweight, oil-free formula makes it suitable even for oily skin types.
You'll notice immediate results – skin feels 55% more hydrated after just one application. Within 1-2 weeks of consistent twice-daily use, skin texture improves noticeably with reduced tightness and flakiness. After 4-6 weeks, the skin barrier is strengthened, reducing sensitivity. For visible anti-aging benefits like plumped fine lines, expect to see results after 8+ weeks of regular use.
Apply E45 Face Hydrating Serum after cleansing and toning, but before heavier treatments and moisturizer. The order is: cleanser → toner (optional) → E45 serum → treatment serums → moisturizer → sunscreen (AM only). For best absorption, apply to slightly damp skin. The serum should always go before oils and creams as it's water-based and needs to penetrate skin first.
No, E45 Face Hydrating Serum will not clog pores. It has a comedogenic rating of 0/5, meaning it's completely non-comedogenic. The formula is oil-free and contains no pore-clogging ingredients. All ingredients have been tested and are suitable for acne-prone skin. The lightweight gel texture absorbs quickly without leaving any residue that could block pores.
E45 Face Hydrating Serum has a 12-month PAO (Period After Opening). Once opened, use within 12 months for best results. Store at room temperature away from direct sunlight. The 30ml bottle typically lasts 2-3 months with twice-daily use (1-2 drops per application). Look for the open jar symbol on the packaging for the exact PAO date.
Verdict: E45 Face Hydrating Serum delivers on its promises of intense, long-lasting hydration in a simple, sensitive-skin-friendly formula. With 70+ years of pharmacy heritage behind it, this serum offers clinically proven results at an accessible price point. The minimal 13-ingredient formula makes it perfect for those who prefer clean, no-fuss skincare. While it won't replace active-focused serums for anti-aging or brightening, it excels at its core job: deeply hydrating dry, sensitive, and eczema-prone skin without irritation. A solid choice for anyone seeking reliable British pharmacy skincare.
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.
