Ingredient breakdown
INGREDIENTSLactic Acid 7%Proven
A gentle yet effective alpha hydroxy acid derived from milk fermentation. Exfoliates the skin's surface layers while simultaneously acting as a humectant to attract moisture. In concentrations above 5%, it is clinically shown to improve skin firmness and reduce hyperpigmentation.
- Function: Chemical exfoliant + humectant that dissolves bonds between dead skin cells
- Benefit: Fades dark spots, evens skin tone, and promotes ceramide production to strengthen skin barrier
- Research: At concentrations of 5–12%, lactic acid has been shown to increase skin thickness and firmness in clinical studies
Glycolic Acid 3%Proven
The smallest and most researched AHA molecule. Penetrates skin effectively to loosen dry, dull cells clinging to the surface and promote smoother, renewed skin underneath. At this concentration, it complements lactic acid without overwhelming the skin.
- Function: Surface-level exfoliant that accelerates cell turnover and loosens dead skin buildup
- Benefit: Visibly smooths rough texture, minimizes the appearance of fine lines, and promotes collagen synthesis at higher concentrations
- Research: Glycolic acid is FDA-recognized as an effective exfoliant for photoaged skin improvement
Saccharomyces/Xylinum/Black Tea Ferment N/APromising
A kombucha-derived ferment filtrate rich in antioxidants, organic acids, and polyphenols from fermented black tea. Works as a prebiotic to support the skin's natural microbiome while delivering free radical protection.
- Function: Antioxidant + prebiotic that supports the skin microbiome and defends against environmental stressors
- Benefit: Helps renew skin radiance, firms appearance, and provides a protective antioxidant shield
- Source: Derived from the symbiotic culture of bacteria and yeast (SCOBY) used in traditional kombucha brewing
Pichia Ferment Lysate Filtrate N/APromising
A tree bark-derived ferment filtrate that helps firm the look of skin and defend against oxidative damage. Works synergistically with the kombucha ferment to enhance overall skin resilience and radiance.
- Function: Skin-firming agent + antioxidant derived from the fermentation of pichia yeast on tree bark
- Benefit: Helps reverse the visible signs of oxidative damage and supports a smoother-looking complexion
L-Arginine + Betaine + Glycerin N/AProven
A trio of hydrating agents that work together to attract and retain moisture in the skin, counteracting the potential dryness from AHA exfoliation. L-arginine also forms a time-release complex with AHAs to reduce irritation.
- L-Arginine: An amino acid and natural moisturizing factor that forms a complex with AHAs for a controlled-release exfoliation effect, reducing irritation
- Betaine: An osmolyte derived from sugar beets that helps regulate cell-water balance and protects skin proteins from denaturation
- Glycerin: A proven humectant that pulls moisture into deeper skin layers, found to be more effective than hyaluronic acid as a moisturizer in some studies

Budget-friendly alternatives (dupes)
DUPESUses 7% glycolic acid as its sole AHA instead of a lactic/glycolic blend. Lacks kombucha ferment and the built-in hydration system. Effective exfoliation at a fraction of the price, but may be slightly more drying.
Contains 7% glycolic acid with apple water and niacinamide. Simpler formula focused purely on AHA exfoliation. Lacks the dual-acid approach and fermented ingredients, but more affordable and widely available.
A gentler 5% glycolic acid toner with aloe vera and ginseng. Lower concentration makes it better for beginners, but less effective for stubborn dark spots. Contains fragrance, unlike the YTTP formula.

Frequently asked questions
FAQThis product is generally not recommended during pregnancy or breastfeeding. It contains glycolic acid, which has a smaller molecular size allowing for greater skin absorption. While lactic acid at low concentrations is often considered acceptable, glycolic acid is flagged by many dermatologists as an ingredient to avoid. Consult your OB-GYN or dermatologist before incorporating this product into your routine during pregnancy or nursing.
No, this product is not considered fungal acne safe. It contains two fermented ingredients—Saccharomyces/Xylinum/Black Tea Ferment (kombucha) and Pichia Ferment Lysate Filtrate (tree bark ferment)—which may feed the malassezia yeast responsible for pityrosporum folliculitis (fungal acne). If you are prone to fungal acne, consider alternatives like The Ordinary Glycolic Acid 7% Toning Solution, which does not contain ferments.
Avoid using this product on the same night as retinol, retinal, or other retinoids, as combining AHAs with retinoids can cause excessive irritation and compromise your skin barrier. Vitamin C (L-ascorbic acid) can also be destabilized by acids, so use vitamin C in your morning routine and this exfoliant at night. Do not layer additional AHA or BHA products on the same evening. You can alternate nights—for example, use this exfoliant 2–3 nights per week and retinol on the remaining nights.
This product works best for oily, combination, and normal skin types looking to address dullness, uneven texture, dark spots, and enlarged pores. It is also suitable for dry skin when followed by a rich moisturizer, thanks to its built-in hydrators. Sensitive skin types should proceed with caution—start with once per week and patch test first. It is not ideal for those with active rosacea, eczema, or fungal acne.
Most users report smoother skin and a visible glow after the very first application. Pore refinement and improved brightness are typically noticeable within 1–2 weeks of consistent use. For dark spot fading and more significant tone evening, expect 4–8 weeks. Full transformative results, including reduction in fine lines and overall clarity, become apparent after 8–12 weeks of regular use (2–3 times per week).
Apply this product immediately after cleansing on dry skin as the second step of your PM routine. Sweep it on with a cotton round, then allow it to absorb for about a minute before layering your serum and moisturizer on top. Do not rinse off. Skip toner on the nights you use this product. Always apply SPF 30 or higher the following morning, as AHAs increase sun sensitivity.
No, this product has a very low comedogenic rating of 1 out of 5. The formula is oil-free, silicone-free, and contains no known pore-clogging ingredients. In fact, AHAs actively help to unclog pores by dissolving the buildup of dead skin cells. The brand also describes it as non-comedogenic. It is very unlikely to cause breakouts, though initial purging (a temporary increase in blemishes as congestion comes to the surface) may occur during the first 1–2 weeks.
The product has a Period After Opening (PAO) of 12 months. Once opened, use within one year for optimal potency and effectiveness. Store in a cool, dry place away from direct sunlight with the cap securely fastened. The amber glass bottle helps protect the formula from light degradation. If the product changes color, develops an unusual odor, or separates significantly, discontinue use.
Verdict: The Youth To The People Kombucha + 10% AHA Power Exfoliant is a well-formulated, leave-on liquid peel that delivers visible results for dull, uneven, and textured skin. Its balanced 7% lactic + 3% glycolic acid blend offers effective exfoliation without being overly harsh, and the inclusion of hydrating agents like betaine and glycerin makes it more skin-friendly than many competitors. The clean, fragrance-free formula and antioxidant-rich kombucha ferment add genuine value. However, the premium price point ($42 for 4 oz), lack of fungal acne safety, and caution needed during pregnancy are notable drawbacks. If budget is a concern, The Ordinary's Glycolic Acid Toner offers similar AHA exfoliation at a fraction of the cost. But for those who want a thoughtfully formulated, multi-benefit exfoliant with built-in skincare benefits, this YTTP product earns its place in a discerning routine.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
