inic acid or causing unwanted flushing.
Consumer feedback indicates that incorporating a dedicated Hyaluronic Acid serum between exfoliating acids and barrier-supportive actives significantly reduces the occurrence of transient redness and
dryness.
Many users note that this buffering technique allows them to enjoy the skin-smoothing benefits of AHAs alongside the tone-evening properties of Niacinamide without experiencing the sensitivity typical

SECTION 3: STEP-BY-STEP MORNING (AM) & EVENING (PM) ROUTINE
To safely harness the combined power of an AHA complex, Hyaluronic Acid, and Niacinamide, a precise layering sequence based on product texture, molecular weight, and pH is essential.
The general rule of cosmetic layering is to apply products from thinnest to thickest consistency, while also respecting the pH requirements of each active.
Because AHAs increase the skin's sensitivity to ultraviolet radiation, the exfoliating portion of this routine is best reserved for the evening (PM).
The morning (AM) routine should focus on antioxidant defense, deep hydration, and barrier protection.

THE EVENING (PM) ROUTINE: TEXTURAL REFINEMENT AND REPAIR
STEP 1: DOUBLE CLEANSE
Begin with a gentle, pH-balanced oil-based cleanser to remove makeup, sebum, and sunscreen, followed by a water-based cleanser.
This ensures a clean canvas, allowing active ingredients to penetrate evenly. Pat the skin dry.
STEP 2: THE AHA COMPLEX (LOW pH ACTIVE)
No.4
Apply your AHA complex (such as a glycolic or lactic acid serum) directly to clean, dry skin. Applying acids to damp skin can accelerate penetration too quickly, increasing the risk of irritation.
Allow the AHA to work undisturbed for 10 to 15 minutes.
This wait time is crucial; it allows the acid to perform its exfoliating function at its optimal low pH before the skin naturally begins to buffer itself back to its physiological pH.
STEP 3: THE HYALURONIC ACID BUFFER (THE HYDRATION BRIDGE)
Mist the face lightly with a basic thermal water or hydrating toner to dampen the skin, as Hyaluronic Acid requires moisture to bind to.
No.5
Apply a generous layer of a multi-molecular weight Hyaluronic Acid serum.
This step instantly floods the newly exfoliated skin with moisture, soothing the epidermis and creating the necessary physical barrier to transition the skin's pH.
STEP 4: THE NIACINAMIDE SERUM (BARRIER SUPPORT)
Once the Hyaluronic Acid has partially absorbed and the skin feels tacky but not wet, apply your Niacinamide serum.
Because the Hyaluronic Acid has buffered the skin's pH and provided a protective moisture cushion, the Niacinamide can be absorbed efficiently without the risk of converting to nicotinic acid or causi

ng flushing.
STEP 5: AGE-DEFYING MOISTURIZER
Seal in the active ingredients with a lipid-rich, age-defying moisturizer containing ceramides, fatty acids, and squalane.
This final step locks in the hydration provided by the Hyaluronic Acid and supports the barrier-strengthening work of the Niacinamide overnight.
THE MORNING (AM) ROUTINE: HYDRATION AND PROTECTION
No.7
STEP 1: GENTLE CLEANSE
Wash the face with lukewarm water or a very mild, non-foaming cleanser to preserve the natural lipids produced overnight.
STEP 2: NIACINAMIDE & HYALURONIC ACID COMBINATION
In the morning, you can bypass the AHA complex entirely to minimize the risk of photosensitivity.
Apply your Niacinamide serum first to provide antioxidant defense and regulate sebum throughout the day.
