Refresh and renew with our 5% lactic acid tonic - a mild AHA treatment that gently exfoliates, brightens, and hydrates for smoother, more radiant skin. This leave-on toner dissolves dead skin cells, fades dullness and dark spots, reduces fine lines, and boosts natural moisture retention without irritation. Perfect for sensitive, dry, or first-time acid users seeking glowing texture and even tone.

Key Benefits of This 5% Lactic Acid Tonic

• Mild Chemical Exfoliation: Clears dead cells for radiant, even-toned skin.
• Hydration Boost: Increases moisture retention for plump, dewy results.
• Brightening & Anti-Aging: Reduces fine lines, dark spots, and dullness gently.
• Sensitive-Skin Friendly: Low irritation potential; suitable for daily use when introduced slowly.
• Texture Refinement: Smooths roughness, minimises pores, and improves overall feel.

This water-based tonic format makes it lightweight, fast-absorbing, and easy to layer-ideal as a post-cleanse step before serums or moisturisers.

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.

How to use :

After cleansing, apply with a cotton pad or clean hands to face and neck (avoid eyes). Pat gently; no rinsing needed. Use AM/PM, starting with every other day to build tolerance, then daily. Always follow with moisturiser and broad-spectrum SPF 30+ in the morning (AHAs increase sun sensitivity). Pair with hydrating ingredients like hyaluronic acid or ceramides for extra comfort.
