| Lasting hydration |
Lactate is a major component of the skin’s Natural Moisturising Factor (NMF); Mg-lactate supplies this humectant in a fully neutral, sting-free form, attracting and binding water in the stratum corneum. |
Improves immediate and 24-h skin hydration and outperforms lactate-free moisturisers in preventing recurrence of dryness. (practicaldermatology.com, onlinelibrary.wiley.com) |
| Barrier reinforcement |
Topically delivered Mg²⁺ up-regulates filaggrin and other differentiation proteins, while lactate stimulates ceramide synthesis—both critical for tight, resilient lipid lamellae. |
Reduces transepidermal-water loss (TEWL) and speeds recovery after barrier insult. (customcompounding.com.au, onlinelibrary.wiley.com) |
| Gentle keratolytic/skin-smoothing |
Lactate (an α-hydroxy acid) loosens corneocyte bonds at pH ≥ 4.5; the magnesium salt form lets formulators harness AHA smoothing without the sting of free lactic acid. |
Softens rough texture and refines fine lines even in sensitive-skin products. (sciencedirect.com) |
| Anti-itch & soothing |
Mg-lactate inhibits histidine-decarboxylase, lowering histamine production in the epidermis—documented in aloe-based gels for atopic or sun-exposed skin. |
Rapid itch relief in after-sun, eczema-soothing and diaper-rash formulas. (mdpi.com) |
| Calm-repair & anti-inflammatory |
Magnesium salts attenuate inflammatory cascades and accelerate re-epithelialisation in minor wounds and dermatitis models. |
Helps quell redness and promotes faster resolution of irritation spots. (mdpi.com) |
| Built-in buffering & antioxidant support |
A 1–5 % solution naturally stabilises formula pH around 5–6 and chelates trace metals, protecting labile actives such as vitamin C or retinoids. |
Enhances both user comfort and shelf-life; no separate neutraliser needed. |
