Lang Wellness AHA Peeling Concentrate: Overnight Exfoliation Formula
If your skin appears dull, feels rough, shows dark spots or blemishes, and doesn't respond to regular cleansing—you may benefit from exfoliation support beyond surface cleaning. This overnight peeling concentrate features 10% Lactic Acid, an ingredient traditionally used to support surface cell turnover and reveal fresher-looking skin.
The Overnight Exfoliation Approach:
10% Lactic Acid is the featured active ingredient—an Alpha Hydroxy Acid (AHA) traditionally used in formulations designed to support surface exfoliation by helping dissolve the bonds holding dead skin cells. Lactic Acid is commonly found in products formulated for those seeking to address cellular turnover appearance, pigmentation concerns, texture smoothness, and improved product absorption. This is chemical exfoliation—formulated to renew without the physical abrasion of harsh scrubs.
1% Hyaluronic Acid provides hydration support during the exfoliation process. AHAs can potentially be drying when used alone, but this formula includes moisture-supporting ingredients to help maintain skin comfort throughout the renewal process.
Organic White Tea Extract provides antioxidants traditionally used in formulations designed to support skin during exfoliation processes and is commonly found in products focused on barrier support.
Organic Sage Extract has been traditionally used in formulations for its natural compounds and is commonly found in products designed for blemish-prone skin.
What You May Experience:
With consistent use over time, users commonly report:
- Noticeably smoother, more refined skin texture within 1-2 weeks
- Gradual improvement in the appearance of dark spots, sun damage marks, and post-acne discoloration over 4-8 weeks
- Brighter, more radiant-looking complexion
- Reduced appearance of fine lines and texture concerns
- Clearer-looking skin (dead buildup can contribute to clogged pore appearance)
- Improved absorption of other skincare products
Important: Individual results vary significantly based on skin type, age, starting condition, consistency of use, and sun protection habits. AHAs increase sun sensitivity—daily SPF is mandatory for safety and results.
How to Use:
⚠️ IMPORTANT: Start Slowly and Build Tolerance
Week 1-2: Introduce Gradually
Evening Application (1-2 times per week ONLY):
-
Cleanse face and pat COMPLETELY dry (damp skin increases penetration and irritation risk)
-
Apply a thin layer of AHA Peeling Concentrate to face, avoiding eye area
-
Leave on overnight (no rinsing required)
-
Morning after: Cleanse gently and follow with moisturizer + Broad-Spectrum SPF 30+ (mandatory—see sun protection warning below)
Week 3+: Increase Frequency as Tolerated
Once skin adapts without irritation, you may increase to 2-3 times per week if no discomfort occurs. DO NOT use nightly unless your skin has built complete tolerance over several weeks.
⚠️ CRITICAL Safety Guidelines:
⚠️ SPF 30+ the next day is MANDATORY – AHAs increase sun sensitivity significantly; UV exposure can worsen pigmentation and cause damage
⚠️ Apply to completely dry skin – Damp skin increases penetration and irritation risk
⚠️ Start conservatively – More frequent use is NOT better; over-exfoliation can compromise your moisture barrier
⚠️ Patch test first – Apply to jawline area, wait 24 hours to check for adverse reactions
⚠️ Avoid mixing with retinoids – Don't use on the same night as retinol/tretinoin (too much active treatment simultaneously)
⚠️ Discontinue if severe irritation occurs – Mild tingling is normal; persistent burning, redness, or peeling means reduce frequency or discontinue
⚠️ Not for use on broken skin – Wait until active breakouts, wounds, or irritation heal before applying
⚠️ Avoid eye area – Keep away from delicate eye skin
⚠️ Pregnancy/nursing – Consult healthcare provider before use
⚠️ Professional treatments – Discontinue 2 weeks before/after chemical peels, laser treatments, or waxing

Understanding AHAs (Alpha Hydroxy Acids):
What are AHAs?
Alpha Hydroxy Acids are water-soluble acids derived from fruits, milk, or sugar. Common AHAs include:
-
Lactic Acid (from milk—used in this formula)
- Glycolic Acid (from sugar cane)
- Mandelic Acid (from almonds)
- Citric Acid (from citrus fruits)
How AHAs Work:
AHAs are traditionally used in skincare to:
- Support surface exfoliation by helping dissolve bonds between dead skin cells
- Promote the appearance of smoother, more refined texture
- Be used in formulations designed for pigmentation concerns
- Support improved absorption of other skincare products
Why 10% Lactic Acid?
-
Lactic Acid is generally considered gentler than glycolic acid (has larger molecular size, penetrates more gradually)
-
10% concentration is commonly found in at-home exfoliation products (professional peels use higher concentrations)
-
This concentration is formulated to provide visible results while being suitable for home use with proper precautions
The Sun Sensitivity Issue:
Critical to understand: AHAs remove surface skin cells, which exposes newer, more vulnerable skin underneath. This skin is significantly more susceptible to UV damage. Without daily broad-spectrum sun protection:
- Risk of worsening pigmentation (the opposite of your goal)
- Increased risk of sun damage and premature aging
- Potential for sunburn even with brief exposure
Daily SPF 30+ is not optional—it's essential for safety and results.
Setting Realistic Expectations:
What This Peeling Concentrate IS:
- A cosmetic exfoliation product featuring 10% Lactic Acid (AHA)
- Designed for overnight application 1-3 times per week (not daily)
- Formulated for those seeking visible improvements in texture, tone, and clarity
- Requires commitment to gradual introduction, sun protection, and patience
What This Peeling Concentrate is NOT:
- An overnight miracle solution (results appear gradually over 4-8+ weeks)
- Suitable for daily use initially (must build tolerance gradually)
- Safe without sun protection (SPF 30+ is mandatory)
- A replacement for professional chemical peels (higher concentrations, professional supervision)
- Appropriate for very sensitive skin, active acne, or rosacea without professional guidance
Timeline for Noticing Changes:
-
Week 1-2: Skin may feel smoother to touch; build tolerance with 1-2x weekly use
-
Weeks 3-4: Users commonly notice improved texture and initial brightness
-
Weeks 6-8: More noticeable changes in dark spot appearance, tone evenness, and overall radiance
-
Weeks 8-12: Continued improvement with consistent use and sun protection
Results require: Consistent use (1-3x weekly), unwavering sun protection (daily SPF 30+), and patience (4-8+ weeks).
When Professional Consultation is Recommended:
Consult a board-certified dermatologist or licensed esthetician if you experience:
-
Severe or persistent irritation (burning, redness, excessive peeling)
-
Worsening pigmentation despite proper use and sun protection
-
Very sensitive skin or rosacea (AHAs may not be appropriate—need professional evaluation)
-
Active acne or skin conditions (may need medical treatment, not cosmetic exfoliation)
-
Interest in stronger treatments (professional chemical peels, prescription retinoids)
- Uncertainty about skin type or appropriate exfoliation method
Remember: Cosmetic AHA products support surface exfoliation and appearance; medical-grade peels and prescription treatments address concerns at deeper levels with professional supervision.
The Bottom Line:
Smooth, radiant-looking skin often benefits from exfoliation support beyond what cleansing provides. This overnight AHA treatment features 10% Lactic Acid, an ingredient traditionally used to support surface cell turnover and reveal fresher-looking skin beneath dead buildup.
However, this product requires significant commitment: gradual introduction (start 1-2x weekly), building tolerance slowly, absolutely mandatory daily broad-spectrum sun protection (SPF 30+ minimum), and patience for gradual results (4-8+ weeks). Without sun protection, AHA use can worsen pigmentation and cause damage—SPF is not optional.
If you're willing to commit to the protocol—gradual introduction, consistent use, and religious sun protection—this concentrate is formulated to support visible improvements in texture, tone, and clarity over time.
Smoother, brighter-looking skin isn't instant—it's the result of strategic exfoliation paired with comprehensive, unwavering sun protection.

Individual results vary dramatically based on skin type, age, starting condition, sun protection habits, and consistency of use. AHAs increase sun sensitivity—daily broad-spectrum SPF 30+ is mandatory for safety. For persistent skin concerns, sensitive skin, or medical conditions, consult a board-certified dermatologist. Cosmetic exfoliation products support appearance; medical conditions and severe concerns require professional evaluation and treatment.
