Frequently asked questions
FAQUse with caution. This product contains chemical UV filters (Avobenzone, Homosalate, Octisalate, Octocrylene) which some healthcare providers recommend avoiding during pregnancy. Always consult your doctor before using any new skincare products while pregnant or breastfeeding. For a pregnancy-safe alternative, consider 100% mineral sunscreens with zinc oxide or titanium dioxide.
No, this product is not considered fungal acne safe. It contains Shea Butter (Butyrospermum Parkii Butter) which can potentially feed malassezia yeast and trigger fungal acne breakouts. If you're prone to fungal acne, look for alternatives without fatty acids, esters, and oils.
Yes! This product is designed to work well with other active ingredients. Use vitamin C serum in the morning underneath this SPF. Use retinol and AHA/BHA at night, as the SPF helps protect retinol-sensitized skin during the day. The 5% niacinamide in this formula is compatible with all these actives.
This product works well for most skin types, especially combination, dry, mature, and normal skin. It's particularly beneficial for those concerned with dark spots, hyperpigmentation, melasma, sun damage, and uneven skin tone. While suitable for oily skin, very oily types may prefer a more mattifying formula.
You'll notice immediate radiance after application. Early brightening effects appear around 2-4 weeks. Visible dark spot reduction typically occurs after 8 weeks of consistent use. For stubborn, persistent dark spots, expect 12-16 weeks for significant improvement. Best results come from pairing with the Mela B3 Serum.
Apply as the last step of your morning skincare routine, after cleansing, toning, serums, and moisturizer (if using a separate one). This product functions as both a moisturizer and SPF. Apply 15 minutes before sun exposure and reapply every 2 hours when outdoors. Can be worn alone or under makeup.
No, this product is labeled non-comedogenic and has a low comedogenic rating of 1/5. It's been tested not to clog pores and is suitable for acne-prone skin (though not for fungal acne due to the Shea Butter content). The formula is also allergy tested and dermatologist tested.
The Period After Opening (PAO) is 12 months. This means you should use the product within 12 months of first opening it. Store at room temperature away from direct sunlight and heat to maintain efficacy. The 40ml size should last approximately 1-2 months with daily facial application.
Verdict: La Roche-Posay Mela B3 UV SPF 30 is an innovative daily moisturizer that combines sun protection with cutting-edge dark spot correction technology. The exclusive Melasyl™ ingredient offers a unique approach to hyperpigmentation by preventing dark spots from forming, not just fading existing ones. While the premium price point and small bottle size may give some pause, the dermatologist-backed formula, elegant texture, and proven results make it a worthy investment for those serious about addressing dark spots and uneven skin tone. Best suited for those who want an all-in-one protection and correction solution, though those with fungal acne concerns or who prefer fragrance-free products should look elsewhere.
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.
