Thick As Thieves Glycolic Lactic Acid Peel

Clinical-Grade Exfoliating Peel with 20% Glycolic + 10% Lactic Acid for Smooth, Radiant Skin.


What It Is

Thick As Thieves Glycolic Lactic Acid Peel is not just an exfoliating peel—it’s a clinical resurfacing treatment designed to reset your skin, fast. Powered by 20% glycolic acid and 10% lactic acid in a pH-optimized formula, this Korean science-backed peel helps fade dark spots, acne scars, fine lines, and rough texture—without stripping your barrier.

If you’ve struggled with dullness, hormonal pigmentation, uneven tone, or breakouts, this chemical exfoliant for face is the breakthrough your skin has been waiting for. Use 1–2 times per week to uncover smoother, clearer, glowier skin—instantly and over time. This is your glow upgrade if you're tired of dull, uneven, or congested skin.

 Key Active Ingredients in Korean Glycolic Acid Peel

  • 20% Glycolic Acid: A powerful AHA that deeply exfoliates, unclogs pores, and stimulates collagen to reduce fine lines and rough patches
  • 10% Lactic Acid: A gentler AHA that hydrates while resurfacing—ideal for dry, sensitive, or aging skin
  • Sodium Hyaluronate (3%): Rehydrates post-exfoliation to plump and smooth skin instantly
  • Birch Juice + Fig + Pomegranate Extracts: Antioxidant-rich botanicals that calm, brighten, and support skin recovery
  • Castor Oil: Moisturizes and reinforces lipid balance to prevent post-peel dryness

Why It’s The Best Glycolic Acid - a Game-Changer

  • Professional-strength formula, safe for at-home use
  • Targets hyperpigmentation, scars, dullness, and wrinkles fast
  • Optimized pH of 3.5 for clinical efficacy without harsh irritation
  • Oil-free, fragrance-free, and melanin-safe
  • Developed in South Korea. Made in the USA

This advanced AHA peel combines chemical exfoliation with Korean herbal extracts for superior performance without compromising skin comfort. It’s the best glycolic lactic acid peel for women and men looking for real results without the downtime of clinical treatments.

Glycolic Lactic Acid Peel vs Drugstore Peels

Visible Results

  • Glow and clarity improve in 2–3 uses
  • Dark spots, roughness, and scars fade in 4–6 weeks
  • Increased firmness and even tone with continued use
  • Ideal for acne-prone, aging, or post-acne skin

How to Use Glycolic Acid 

  1. Apply a thin layer to clean, dry skin at night
  2. First 2 weeks: Leave on for 5–10 minutes, then rinse and follow with a barrier-repairing moisturizer
  3. After 3 weeks: Leave on overnight (if well tolerated), then rinse in the morning
  4. Always follow with SPF the next day (e.g., Habaek SPF50)

Do not use on broken or irritated skin. Avoid layering with other exfoliants or retinoids on the same day.

FAQ

What is a Glycolic Lactic Acid Peel?

A glycolic lactic acid peel is a type of chemical peel that combines two alpha hydroxy acids, glycolic and lactic acids, to exfoliate the skin. This treatment helps to remove dead skin cells, promoting the regeneration of new skin, and enhancing overall texture and appearance.

Who is the ideal candidate for a Glycolic Lactic Acid Peel?

While many with varying skin types can benefit from this peel, it's particularly effective for individuals with dull, aging, or sun-damaged skin

How should I prepare my skin for a Glycolic Lactic Acid Peel, and what should I do after the treatment?

Before a peel, cleanse your skin and avoid using other skincare products. Post-treatment, hydrate and protect the skin by applying a gentle moisturizer and a broad-spectrum SPF.

When should I use it?

For optimal skin care, consider a night peel routine that gently rejuvenates your complexion while you dream. Glycolic acid peel and Lactic acid peel give you the benefits of smoother, brighter skin. Remember, brevity is key in skincare peels, so always heed recommended instructions and incorporate suitable intervals in your beauty regimen!

I have sensitive skin. Can I use it?

Yes, you can. We recommended you start with 20 mins and increase the time as your skin gets used to it

Can I combine a Glycolic Lactic Acid Peel with other skincare products or treatments?

It's advisable to use the peel with caution when combined with other skin care products, especially those containing retinol or other acids. Wait at least 24 hours before using other treatments to avoid over-exfoliation.

BEST thing you can do for your skin

I am a Gymsegbe customer, 62 years, and have used all of their products, so I decided to try this out. I have had professional peels before and have bought another brands peel worth $230. This is by far the best peel I have used. It has made my pores smaller, reduced my wrinkles, and left my skin very soft and smooth in a very short time. I simply love it and the price!
