Frequently asked questions
FAQYes, lactic acid at 5% concentration is generally considered safe during pregnancy and breastfeeding according to dermatologists. It's one of the few AHAs considered low-risk during pregnancy. However, always consult your healthcare provider before using any new skincare products during pregnancy or while nursing.
Yes, this product is fungal acne safe. It's free from fatty acids, oils, esters, polysorbates, and fermented ingredients that can feed malassezia yeast. The formula contains no known fungal acne triggers, making it an excellent exfoliation choice for those with pityrosporum folliculitis.
Do not use in the same routine as retinoids, pure vitamin C (L-ascorbic acid), other direct acids (like glycolic, salicylic, or mandelic acid), EUK 134, copper peptides, or peptide serums. You can alternate these products on different days or use them in separate AM/PM routines, but never layer them together.
This product is ideal for dry and sensitive skin types, as well as beginners to chemical exfoliation. Lactic acid is gentler than glycolic acid and has hydrating properties. It's also excellent for combination skin, acne-prone skin (it's non-comedogenic), and those with fungal acne. Oily skin types may prefer the stronger 10% version.
Most users notice smoother skin texture within 1-2 weeks of consistent use. Visible brightness and radiance typically appear by weeks 3-4. More significant improvements in skin tone, hyperpigmentation, and overall texture are usually seen after 6-8 weeks. For optimal results, use consistently for 3+ months.
Apply after cleansing on dry skin, before other serums and moisturizers. Use in the PM only (evening routine). The order is: Cleanser → Toner (optional) → Lactic Acid 5% → Water-based serums → Moisturizer. Always apply sunscreen the next morning as AHAs increase sun sensitivity.
No, this product has a comedogenic rating of 0/5. It's oil-free, silicone-free, and contains no pore-clogging ingredients. In fact, regular use of AHAs like lactic acid can help unclog pores by dissolving dead skin cell buildup, making it beneficial for acne-prone skin.
The product has a PAO (Period After Opening) of 12 months. The amber glass bottle helps protect the formula from light degradation. Store in a cool, dry place away from direct sunlight and humidity. The 30ml bottle typically lasts 2-3 months with daily use.
Verdict: The Ordinary Lactic Acid 5% + HA is an exceptional value for a gentle, effective AHA exfoliant. At just $8.10, it delivers results comparable to products 10x its price, making it the gold standard for budget-friendly chemical exfoliation. The addition of hyaluronic acid and Tasmanian pepperberry makes it uniquely suitable for sensitive and dry skin types who typically struggle with acids. While those seeking dramatic, fast results may prefer the 10% version, this formulation is perfect for building skin tolerance, maintaining results, or for anyone who values gentle, consistent skincare over aggressive treatments.

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.
