Seeking effective exfoliation without the sting? Our 5% lactic acid treatment tonic delivers the perfect entry-level AHA experience. Lactic acid — a naturally derived, milk-based alpha hydroxy acid — stands out as one of the gentlest yet most rewarding exfoliants, especially for sensitive, dry, or reactive skin. At 5%, this concentration provides noticeable brightening, texture refinement, and hydration support while minimising irritation risks associated with stronger AHAs like glycolic acid.
Why 5% Lactic Acid Is Ideal for Gentle Yet Visible Results
Lactic acid works by loosening the bonds between dead skin cells on the surface, promoting faster cell turnover for a fresher, smoother complexion. Unlike harsher acids, it also functions as a humectant, drawing in and helping retain moisture (part of the skin's natural moisturising factor), which leaves skin softer, plumper, and less prone to dryness. Dermatological insights and user studies highlight that 5% lactic acid visibly:

Improves brightness and evens tone by fading dullness, hyperpigmentation, and mild dark spots
Smooths fine lines and rough texture for a more refined appearance
Enhances hydration and barrier function, making it excellent for dry or dehydrated skin
Gently unclogs pores and reduces bumpy texture without over-stripping

At this level, it's often recommended for beginners or sensitive types, with many seeing brighter, softer skin in 4–8 weeks of consistent use.
