Frequently asked questions
FAQCaution is advised. Altruist SPF 50 contains chemical UV filters including avobenzone, octocrylene, and octisalate, which can be absorbed through the skin. While not strictly contraindicated, most dermatologists recommend using mineral-only sunscreens (with only zinc oxide and/or titanium dioxide as active ingredients) during pregnancy and breastfeeding. Consult with your healthcare provider for personalized advice.
No, Altruist SPF 50 is NOT fungal acne safe. It contains ingredients that can potentially feed Malassezia yeast, including Ethylhexyl Stearate (an ester), Cetearyl Alcohol (a fatty alcohol), and Glyceryl Stearate. If you suffer from fungal acne or pityrosporum folliculitis, look for sunscreens specifically formulated to be FA-safe.
Yes! Altruist SPF 50 is compatible with all common active ingredients. Apply your vitamin C serum in the morning before sunscreen. For retinol, AHAs, and BHAs, use these in your evening routine, then apply Altruist as the final step of your morning routine. The high UVA protection actually makes it an excellent choice when using photosensitizing actives like retinol.
Altruist SPF 50 is best suited for dry, normal, and sensitive skin types. The moisturizing formula with glycerin and panthenol provides excellent hydration. Those with oily skin may find it too dewy - consider the Altruist Face Fluid (lighter texture) or a different mattifying sunscreen. It's excellent for sensitive skin as it's fragrance-free and hypoallergenic.
UV protection is immediate upon application. However, the visible anti-aging and skin-protecting benefits develop over time with consistent daily use. After 2-4 weeks, you may notice reduced sun-induced redness. After 1-3 months, skin texture improvements from prevented UV damage become apparent. The long-term anti-aging benefits (prevention of wrinkles, age spots, and loss of elasticity) accumulate over years of diligent use.
Sunscreen is ALWAYS the last step of your skincare routine, before makeup. The correct order is: 1) Cleanser, 2) Toner/Essence (optional), 3) Serum/Treatment, 4) Moisturizer (optional - Altruist is moisturizing enough to skip this), 5) Sunscreen, 6) Makeup. Wait 1-2 minutes between sunscreen and makeup for best results.
Altruist SPF 50 has a comedogenic rating of approximately 1 out of 5 - meaning it is unlikely to clog pores for most people. It is marketed as non-comedogenic. However, individual reactions can vary. The Cetearyl Alcohol has a comedogenic rating of 2, which is still considered low. If you're highly prone to clogged pores, patch test on a small area first.
Altruist SPF 50 has a Period After Opening (PAO) of 12 months. This means the product remains effective and safe to use for 12 months after you first open it. Store in a cool, dry place and keep the cap tightly closed. If the texture, color, or smell changes significantly, discontinue use. With generous daily application (which is recommended!), a 200ml pack typically lasts 2-3 months for face and neck use.
Verdict: Altruist Dermatologist Sunscreen SPF 50 delivers exceptional value with its professional-grade PPD 54 UVA protection at a fraction of luxury brand prices. Created by a UK skin cancer surgeon and formulated with advanced Tinosorb filters not available in the US, it offers some of the best broad-spectrum protection money can buy. While not suitable for those with fungal acne or seeking a pregnancy-safe mineral formula, it's an outstanding choice for dry, normal, and sensitive skin types who want maximum sun protection without breaking the bank. The moisturizing, fragrance-free formula makes it ideal for daily wear, and the charitable mission adds feel-good value. A deserving cult favorite in the skincare community.
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.
