The milk moisturising trend has taken over beauty feeds, with lactic acid body lotions and Cleopatra-style milk baths promising baby-soft, glowing skin. However, this viral skincare staple may not be suitable for everyone. Here is why it can cause more harm than good for certain skin types.
When the Barrier Breaks
If you have eczema, rosacea, or psoriasis, lactic acid might worsen your condition. While it is marketed as the gentlest AHA, it still dissolves dead skin cells. When your skin barrier is compromised, this can lead to stinging, burning, and inflammation.
The Sneaky Sunscreen Trap
Lactic acid accelerates cell turnover, revealing fresh skin that is highly vulnerable to UV rays. Without proper sunscreen, especially for deeper skin tones, it can trigger post-inflammatory hyperpigmentation, causing dark patches instead of smooth skin.
The Raw Milk Reality Check
Lab-formulated lactic acid differs from raw milk. Applying milk proteins can cause hives and itching in those with dairy allergies. Raw milk also lacks occlusive ingredients to lock in moisture, and its natural fats can clog pores, leading to body acne.
Scrubbing Away Your Sanity
Combining lactic acid lotion with physical scrubs or salicylic acid body washes over-exfoliates the skin. Signs include tightness, a plastic-like shine, micro-tears, and redness.
It is All About the Percentages
Concentration matters. Lotions under 5% act as humectants, ideal for dry skin. Concentrations of 10% or 12% become potent chemical peels, effective for strawberry legs but too harsh for sensitive skin, causing blistering and flaking. Always check percentages and never skip SPF.
