Chemical exfoliation produces better, more consistent skin renewal than physical scrubbing. The challenge for sensitive, reactive and rosacea-prone skin is that most chemical exfoliants, even gentle ones, trigger the inflammatory responses that sensitive skin cannot tolerate. Lactic Acid at the right concentration, with DermShield Technology suppressing the neurogenic inflammatory pathway, changes this entirely.NOON Lacto-S is the entry-level lactic acid renewal treatment in the NOON range, formulated specifically for sensitive, dry and rosacea-prone skin that cannot tolerate standard chemical exfoliants. A gentle, low-concentration Lactic Acid cream with DermShield Technology providing daily gentle resurfacing, hydration and brightening without any of the irritation that prevents sensitive skin patients from using acid products consistently.Who Is It For? Sensitive, dry and rosacea-prone skin wanting gentle daily acid renewal without irritation Those new to chemical exfoliation who want to start at the gentlest appropriate point Those on GLP-1 medications with reactive skin needing gentle daily renewal Post-procedure skin reintroducing gentle acid products after a treatment pause Those wanting to build lactic acid tolerance before progressing to Lacto 10 How Does It Work?Lactic Acid at a low concentration gently loosens dead skin cell bonds at the surface, accelerating gentle cellular turnover without the rapid penetration and inflammatory stimulation of higher-concentration or smaller-molecule AHAs. Lactic Acid also provides humectant hydration as it exfoliates, making it uniquely appropriate for dry and sensitive skin where glycolic acid would cause dryness and irritation. DermShield Technology suppresses the neurogenic inflammation that would otherwise make even low-concentration acid use uncomfortable for reactive skin types.Key Ingredients Lactic Acid (low concentration): The most hydrating of the AHAs, with a larger molecular weight than glycolic acid that produces gentler, more gradual resurfacing appropriate for sensitive skin. Provides gentle cellular renewal and brightening alongside humectant hydration. DermShield Technology (patented, NOON Aesthetics): Suppresses neurogenic inflammation to enable daily lactic acid use on even the most sensitive and reactive skin types without any discomfort or barrier disruption. Benefits Gentle daily lactic acid resurfacing for sensitive and reactive skin Humectant hydration alongside exfoliation Brightens and improves skin clarity without irritation DermShield enables daily use on rosacea-prone and reactive skin Entry-level acid renewal before progressing to Lacto 10 or Lacto 15 Appropriate for post-procedure gentle acid reintroduction What Results Can You Expect?At 2 weeks: improved skin radiance and early texture improvement with consistent daily use. At 4 to 6 weeks: progressive brightening, smoother skin texture and improved clarity. Long-term: consistent gentle renewal that maintains skin quality as the foundation for progressing to higher-concentration lactic acid treatments.How We Use It at Face for SoulAs a pharmacist prescriber specialising in skin health, Lacto-S is where I start every sensitive skin patient who needs acid renewal but has been unable to tolerate standard chemical exfoliants.
