When and How to Apply:

Evening Application: This serum is designed for nighttime use. After cleansing and toning (if applicable) in the evening, apply Retinal Infusion MLV10 Serum to dry skin. Dispense a small amount (approximately a pea-sized quantity or 1-2 pumps) and gently spread it over the face and neck, avoiding direct contact with the eyes and lips.

Frequency: Start by using the serum 1-2 times per week (e.g. every other night) to allow your skin to acclimate. Gradually increase usage to nightly as tolerated.

Layering: Allow the serum to absorb for a minute or two. Follow with a moisturizer to lock in hydration and further minimize any potential dryness (barrier-focused moisturizers such as Vitamin B Activated All-In-One Concentrate or Concentrated Revitalizing Lifting Mask pair well, especially in the first few weeks of use). Avoid applying other potent actives (such as AHAs/BHAs or other retinoids) in the same routine as this serum, as the formulation is already high-strength. Instead, those can be used on alternate nights if needed.

Sun Protection: In the morning, apply a broad-spectrum sunscreen (SPF 30 or higher) as part of your routine. Retinal (like all retinoids) can increase the skin’s sensitivity to the sun, so diligent daily sun protection is critical to maintain results and prevent UV-induced damage. (This is especially important given the serum’s resurfacing action; new skin is more fragile to UV.)

Consistency for Best Results: Use the serum consistently as directed. Visible improvements in texture and tone can typically be seen within a few weeks. Regular follow-ups can help adjust usage if needed (for example, if mild irritation occurs, scale back frequency or mix a drop of the serum with a moisturizer to buffer). Please note that retinoid therapy is a long-term investment in skin health – continued use yields sustained benefits.

Safety and Caution:

Sun Sensitivity: This product contains a retinoid (retinaldehyde) which can increase skin’s sensitivity to UV light. Apply sunscreen every morning (and reapply throughout the day) and minimize direct sun exposure while using the serum. Tanning beds are not recommended.

Gradual Introduction: Introduce the serum gradually into your routine (as noted above). Mild redness, dryness, or flaking can occur initially – these are normal signs of retinoid activity. If excessive irritation occurs, pause use for a few days and moisturize generously. You can restart at a lower frequency once skin calms.

Avoid Sensitive Areas: The serum is formulated for the face and neck. Avoid applying on the immediate eye area (eyelids or lips) and on any broken or eczematous skin. If accidental contact with eyes occurs, rinse thoroughly with water.

Do Not Combine with Other Retinoids: Because this is a potent retinal serum, do not use other retinol/retinoid products concurrently on the same day, as this may increase the risk of irritation. It’s also wise to avoid combining with strong exfoliating treatments (like high-percentage AHAs or peels) on the same night. If additional exfoliation or actives are desired, they should be used on alternate days or mornings as tolerated.

Pregnancy and Nursing: As a precaution, vitamin A derivatives are generally not recommended during pregnancy or while breastfeeding. Consult with a physician before use if pregnant, nursing, or trying to become pregnant.

General Safety: For external use only. Keep out of reach of children. Discontinue use if you experience any persistent adverse reactions (such as severe irritation, hives, or swelling) and consult a healthcare professional if needed.

Store the serum in a cool, dark place to maintain ingredient stability (the formulation is well-stabilized, but extreme heat or direct sunlight on the bottle should be avoided). Always ensure the cap is tightly closed after use to prevent oxidation of the product.
