At Reng Xin, every skincare recovery program and formulation is individually customized based on each customer’s skin condition, consultation responses, sensitivity profile, recovery goals, and overall skin history.

Because personalized skincare is highly individual, customers acknowledge and understand that results, recovery speed, skin response, and overall experience may vary significantly from person to person.

---

Individual Skin Response

Each customer’s skin condition is influenced by many factors, including but not limited to:

• Skin severity and duration of the condition

• Genetics and immune response

• Allergies and sensitivities

• Environmental exposure

• Climate and humidity

• Lifestyle habits

• Diet and stress levels

• Previous skincare or medical treatments

• Consistency of product usage

As a result, no identical outcome, timeline, or level of improvement can be guaranteed for every individual.

---

Recovery Timeline Expectations

Some customers may experience visible comfort, hydration support, or irritation reduction within the first 1–2 weeks of use.

However, deeper skin barrier recovery, long-term stabilization, and visible improvement for chronic skin conditions may require:

• Several weeks of consistent use

• Formula adjustments

• Ongoing monitoring

• Lifestyle modifications

• Extended recovery periods depending on skin severity

Customers understand that personalized skincare recovery is a gradual process and not an instant-result cosmetic treatment.

---

No Guaranteed Outcome

While we aim to provide high-quality personalized formulations and ongoing support, customers acknowledge that:

• Individual skin response cannot be predicted with certainty

• Results differ between individuals

• Certain skin conditions may respond slowly

• Some customers may require formulation adjustments over time

• Recovery progress may fluctuate during the adjustment period

Customers agree that purchasing a personalized skincare program does not constitute a guarantee of:

• Complete recovery

• Permanent remission

• Specific cosmetic results

• Fixed recovery timelines

• Uniform outcomes across all customers

---

Personalized Formulation Adjustments

Because our formulations are customized and continuously optimized, ingredient combinations, texture, consistency, and concentration levels may vary between customers or between production batches.

Adjustments may be made based on:

• Skin feedback

• Sensitivity reactions

• Recovery progression

• Environmental changes

• Consultation updates

Minor changes in:

• Texture

• Color

• Scent

• Thickness

• Absorption feel

are considered normal characteristics of personalized skincare formulations.

---

Skin Sensitivity & Adjustment Period

Customers understand that temporary skin reactions may occur during the adjustment process, including:

• Mild dryness

• Temporary redness

• Skin purging

• Sensitivity fluctuations

• Temporary irritation

These reactions may vary depending on:

• Existing skin damage

• Previous treatments

• Ingredient tolerance

• Skin barrier condition

Customers are responsible for discontinuing use and seeking professional medical guidance if severe irritation, allergic reactions, or unexpected complications occur.

---

Consultation Accuracy Responsibility

The effectiveness and suitability of personalized formulations depend heavily on the accuracy of information provided during consultation.

Customers agree to provide truthful and complete information regarding:

• Allergies

• Current medications

• Existing treatments

• Skin sensitivities

• Medical history relevant to skincare

Failure to disclose accurate information may affect formulation compatibility, skin response, and overall recovery outcomes.

---

Support & Monitoring

Reng Xin may provide ongoing guidance, monitoring, or formulation adjustments depending on the selected recovery program.

However, customers acknowledge that:

• Support recommendations are based on customer-provided information

• Consistent communication is necessary for proper monitoring

• Failure to follow instructions may affect results

• Long-term recovery depends on multiple individual factors outside our control

---

Cosmetic & Wellness-Oriented Service

Reng Xin provides personalized skincare and wellness-oriented recovery support programs.

Our services are designed to support:

• Skin comfort

• Barrier recovery

• Hydration balance

• Personalized skincare management

Our products and consultations are not intended to replace emergency medical care, licensed dermatological treatment, or direct physician supervision when clinically necessary.

Customers with severe medical conditions, infections, or urgent dermatological concerns are encouraged to consult licensed healthcare professionals.

• Personalized skincare results vary between individuals
