Why Choose Age Perfect Serum Le Duo?

To effectively address visible signs of aging, skin often needs more than one type of serum. Age Perfect Serum Le Duo delivers two targeted formulas in a single step, combining nourishing care with active performance. This dual-serum approach helps support skin that looks firmer, smoother, and more even-toned, making it an efficient and effective option for those seeking visible anti-aging results without complicating their routine.

What It Helps With

Age Perfect Serum Le Duo helps address multiple visible signs of aging associated with collagen loss and uneven skin tone. With continued use, it supports smoother-looking skin, improved firmness, enhanced radiance, and a more even complexion. Fine lines and wrinkles appear reduced, while skin feels more plump, comfortable, and revitalized.

*Biosynthetic collagen peptide similar to a protein fragment found in collagen.
**Ascorbyl Glucoside – stabilized form of Vitamin C.

WHO SHOULD USE

Best for:

• Fine lines and wrinkles
• Loss of firmness and elasticity
• Uneven skin tone and dullness
• Skin lacking radiance and smoothness

Skin type: Suitable for all skin types, including sensitive skin and all skin tones

HOW TO USE (ROUTINE STEPS)

Step 1 Cleanse:
Start with a gentle cleanser to remove makeup, sunscreen, and impurities.
• Cleanser: Revitalift Derm Intensives 3.5% Pure Glycolic Acid Gel Facial Cleanser

Step 2 Treat:
Apply Age Perfect Serum Le Duo to visibly target fine lines, wrinkles, loss of firmness, and uneven tone.

First use: Press the center of the pump several times until both formulas dispense evenly.

Daily use: Press the pump once to release both serums. Apply evenly to face and neck using upward motions. Use AM + PM.

Step 3 Moisturize:
Follow with your daily moisturizer to seal in hydration and support skin firmness.
• Moisturizer: Revitalift Triple Power Anti-Aging Moisturizer. Use AM + PM.

Pro Tip:
The dual-serum texture absorbs quickly and layers well under moisturizer, makeup, and sunscreen without feeling greasy or heavy.

Terrible Design of the product

6 months ago
While this does feel great on the skin, it's packaging is very deceiving. It looks pretty, and it looks like you can visually see the product as each chamber is the color of what comes out. HOWEVER, you can not see how much you have used or what you have left. I used it twice a day for ONLY 15 days and was out. Now going by the color of the chambers it appeared full. I weigh 117 pounds and it's not like my face is the size of a football field. I paid $30 for this at WalMart. Also, the hole on the cream side will clog and trying to pump the product out is challenging. You need a new design or a way to make it easier for a consumer to see how much product is left. This is an awful design flaw. Because of this I doubt highly I would repurchase it, and I seriously would not recommend it to anyone because of the design and being unable to see what has been used and what you have left.

      · 9 months ago  

      Hi there! Thank you for reaching out to us about the differences between the Age Perfect Serum Le Duo and the Age Perfect Cell Renewal Midnight Serum are fantastic anti-aging products, but they are formulated with different key ingredients and designed to address specific concerns and usage times The Midnight Serum is a powerhouse anti-aging serum with a specific focus on overnight skin renewal, leveraging the time when your skin's natural regeneration process is most active. While the Le Duo serum is a truly innovative product, featuring a 2-in-1, dual-chamber design. This means that with every pump, you're getting two distinct formulas that work synergistically. We hope this helps and if you need further information on the best suited products for you please call us directly at 1-800-322-2036, M-F 9am to 5pm est.
