Are your wrinkles and fine lines becoming more visible?
Tired of dull skin, uneven tone, texture and stubborn signs of aging?
Glycolic Acid vs. Retinol for Anti-Aging.
Discover the Metrin Accelerated Performance System—a powerful, all-in-one exfoliating and hydrating duo featuring Glycolic Acid (AHA), designed to reveal a brighter, more youthful complexion. If you’ve been exploring Glycolic Acid, Retinol, tretinoin, or other anti-aging solutions, this is the proven, painless, safe, effective and easy to use skincare treatment to meet your skincare needs.
What is the Accelerated Performance System?
Our innovative, esthetician recommended system combines the deep exfoliating power of Glycolic Acid (AHA) and a rejuvenating, healing hydrating serum, delivering professional-level exfoliation, hydration, and nutrients right at your fingertips. Whether you’re new to skincare or a seasoned enthusiast, this system is perfect for tackling dullness, wrinkles, hyperpigmentation, and uneven skin tone.
Why Choose the Accelerated Performance System?

Experience the Power of Glycolic Acid
Glycolic Acid is known as the most effective Alpha Hydroxy Acid (AHA) due to its ability to deeply penetrate the skin, making it ideal for exfoliating dead skin cells, stimulating cell renewal, and boosting collagen production. Metrin’s Revitalizing Glycolic Acid boasts a high level of excellent quality Glycolic Acid, initiating intensive deep exfoliation and cell renewal.
Say goodbye to dull skin and hello to a brighter, smoother complexion.

Deep Hydration with Reactivating Serum
Our serum is infused with aloe vera, gentle glycerin, and herbal extracts like Arnica, Chamomile, and Yarrow, to soothe the skin while enhancing the benefits of Glycolic Acid. Experience intense hydration that leaves your skin feeling revitalized. The Reactivating Serum is an imperative step of the Accelerated Performance System. It moisturizes, heals, sooths and calms, which allows for you to experience a deep exfoliation without purging, redness or burning. These symptoms are often seen as a side effect from lesser products’ poor quality, or poor balance of, exfoliating ingredients, and lack of follow up hydration. Avoid skin purging, redness, and burning by using the esthetician’s recommended Accelerated Performance System.
Glycolic Acid vs. Retinol: Which is Right for You?
Glycolic Acid and Retinol are two powerhouse ingredients in anti-aging skincare, but they work in different ways.
Here’s how they compare and why Glycolic Acid might be your go-to choice for deep exfoliation and skin renewal treatments:
Benefits of Glycolic Acid
- Immediate Exfoliation: Works on contact to remove dead skin cells, revealing smoother, glowing skin.
- Boosts Collagen: Stimulates collagen production to reduce fine lines and wrinkles.
- Suitable for All Skin Types: Less likely to cause irritation compared to Retinol, making it safe for sensitive skin.
- Combats Hyperpigmentation: Helps fade dark spots, age spots, acne scars, and uneven skin tone.
Benefits of Retinol
- Targets Fine Lines: Retinol works over time to stimulate cell turnover and improve skin texture.
- Reduces Blemishes: Known for its effectiveness in reducing acne and refining pores.
Why Choose Glycolic Acid for overnight deep exfoliation treatments?
Glycolic Acid offers faster, visible results with exfoliation and hydration benefits all in one. While Retinol can be highly effective, Glycolic Acid provides an instant glow without the wait, and it’s gentler on your skin. Experience the best of both worlds with Metrin’s Accelerated Performance System, which prioritizes Glycolic Acid for immediate rejuvenation.
(Our daily use skin care products such as #3 Vita Conditioner and #5 Enriched Vita Conditioner contain Vitamin A/ retinol. This way you can provide your skin daily with this powerful anti-ageing skin care ingredient which works over time without over-exposing your skin to it causing unwanted skin burning or purging, and still access the immediate glow that only a well formulated glycolic acid can offer with the Accelerated Performance System.)
Essentially when it comes to Glycolic Acid vs. Retinol for Anti-Aging, while they are both incredible ingredients not to be left out of your skin care routine, they both have their time and their place. For an immediate glow and long lasting antiaging effects, glycolic acid as an overnight treatment is the way to go. As a small dose daily use ingredient, retinol is perfect. As retinol works over time and can cause irritation, to get its best effects without skin purging, irritation or burning, look for moisturizers with retinol/ vitamin A in the ingredients. This will provide your skin with smaller doses of vitamin A/ retinol that your skin can absorb without irritating it, allowing it to reap its long term benefits of antiaging.

How to Use for Maximum Results
Revitalizing Glycolic Acid:
Apply this exfoliating treatment one to three times per week, at night, to clean skin before bed (double cleanse with Metrin’s Double Cleansing Duo to ensure fully cleansed skin) to dissolve dead cells and promote cell renewal.
Gently smooth onto areas to be treated (do not massage) and leave on overnight.
This product may also be applied directly to blemishes, insect bite scars to help exfoliate and encourage skin renewal.
Reactivating Serum:
In the morning, after a night treatment of Revitalizing Glycolic Complex, double cleanse the skin again with Metrin’s Double Cleansing Duo. Gently smooth a liberal amount of Reactivating Serum to the face and neck. Enjoy as it cools, sooths and hydrates. (Optional: Follow with the final steps of the Metrin® Skincare System for maximum skin nourishment and hydration!)
This product is particularly effective in sealing in hydration and as an eye serum applied under the eyes to hydrate and de-puff the under-eye area, as it contains powerful anti-inflammatory ingredients.
