Lactic acid and betaine
Work well together
Use lactic acid first, then apply betaine to restore moisture since acids can dry skin. Lactic acid gently exfoliates, while betaine replenishes lost water so the skin stays comfortable. If tingling happens, use a lower strength or space them further apart.
