🔬 Ingredient Breakdown
🧪 Lactic Acid 5% Proven
An alpha hydroxy acid (AHA) derived from milk fermentation that gently exfoliates the skin's surface, promotes cell turnover, and helps improve skin texture and tone.
- Mechanism: Breaks down bonds between dead skin cells for gentle exfoliation
- Benefits: Smoother texture, improved radiance, reduced appearance of fine lines
- Advantage: Larger molecule than glycolic acid, making it gentler and more hydrating
💧 Sodium Hyaluronate Crosspolymer 2% Proven
A crosslinked form of hyaluronic acid that creates a smooth film on skin and provides extended hydration benefits.
- Water-Binding: Holds up to 5x more water than regular hyaluronic acid
- Sustained Release: Continuously delivers moisture over time
- Source: Based on FDA-approved dermal filler technology (Hylan B gel)
🌿 Tasmanian Pepperberry Extract Promising
A purified botanical extract from Tasmannia Lanceolata known for its anti-inflammatory and soothing properties.
- Function: Reduces signs of inflammation and sensitivity from acid exfoliation
- Note: Natural color variation may occur seasonally in the formula
🌊 Glycerin Proven
A powerful humectant that attracts and retains moisture, keeping skin hydrated and supporting the skin barrier.
- Research: Studies show glycerin can be more effective than hyaluronic acid as a humectant
- Benefits: Improves skin hydration, barrier function, and has antimicrobial properties

❓ Frequently Asked Questions
Yes, 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.
