General Terms and Conditions of the CosMedics® medical beauty institute, Magdalini Tseliou - Menzer Weg 6 - 14165 Berlin - Tel.: 03068975188 - © 2026
Section 1 General Provisions, Scope of Application 1. These General Terms and Conditions (GTC) apply to all our business relationships with our customers. 2. Our GTC apply exclusively. Deviating, conflicting, or supplementary terms and conditions of the customer shall only become part of the contract if and to the extent that we have expressly agreed to their validity. This requirement of express agreement applies in all cases, for example, even if we perform our services without reservation despite being aware of the customer's terms and conditions. Section 2 Offers Services
Our offers are subject to change and non-binding. 1. The institute offers cosmetic and device-based treatments in the field of skin health, in particular facial and body treatments, scalp treatments, device-based cosmetic treatments (e.g., microdermabrasion, SkinPen microneedling, HydraFacial, JetPeel, Dermatude MetaTherapy, etc.), individual skin concepts, as well as the sale of skincare products and gift certificates. 2. All treatments serve cosmetic care and skin improvement. No medical diagnoses are made, no promises of healing are given, and no medical treatments are performed.
3. Pigmentation
No guarantee is given for the longevity, color intensity, or exact shade, as these depend on individual skin type and metabolism. The treatment is performed at the customer's own request.
Section 3 Appointments, Treatments, Contracts 1. Treatments are available upon request and by appointment to all legally competent persons aged 18 and over. For persons under 18, their legal representative must schedule the appointment and thus conclude the treatment contract. 2. If the client requests a specific appointment time, we will try to accommodate this request. However, due to the large number of appointment requests, this is not always possible. 3. Scheduled cosmetic appointments are a service contract pursuant to Section 611 of the German Civil Code (BGB) and are therefore binding. Permanent makeup is a contract for work and services pursuant to Section 631 of the German Civil Code (BGB). 4. The duration and scope of treatment depend on the prior individual consultation and the client's skin condition. We provide treatment recommendations; the client makes the final decision regarding the type of treatment. If we are unable to keep an appointment due to reasons beyond our control or force majeure, the client will be informed immediately, provided the stored address and contact details allow for timely communication. In this case, we are entitled to reschedule the appointment at short notice or to withdraw from the contract. Our statutory rights of withdrawal and termination remain unaffected. § 4 Customer's Failure to Appear 1. If the customer fails to appear for the agreed treatment appointment and does not cancel it at least 48 hours in advance, we are entitled to charge the customer the full amount of the booked treatment as a cancellation fee in accordance with §§ 611, 615, and 642 of the German Civil Code (BGB). Payments already made will be forfeited and will not be refunded. The customer is not entitled to a replacement service. In the event of a no-show or late cancellation, the customer has the option of providing proof of the reason, such as unforeseen events, illness, accidents, or death, in order to avoid the cancellation fee. Prepaid or deposited amounts will not be refunded for timely cancellations but will remain as credit for future appointments. 2. In case of late arrival, treatment is only available for the agreed treatment duration. We are also entitled to charge for the full treatment time if the treatment must be ended promptly due to a subsequent appointment. § 5 Prices and Payment Terms 1. Unless otherwise agreed in individual cases, our prices valid at the time of booking the appointment apply. 2. The agreed prices are due upon completion of the treatment. In justified cases, appointments can only be accepted after advance payment. Deposits are non-refundable. A deposit must be paid again if an appointment cannot be kept, regardless of the reason. 3. Payments must be made in cash, via PayPal, instant bank transfer, or by card payment plus a 1.4% transaction fee, or in exceptional cases by invoice and bank transfer. This also applies to the sale of products or vouchers. § 6 Warranty 1. During the treatment, products appropriate to the needs of the individual skin type are used. However, no guarantee regarding compatibility and success can be given. This applies in particular if questions during the preliminary consultation were not answered sufficiently or truthfully by the customer. 2. The customer must notify us of any obvious treatment defects within 10 calendar days of discovering the defect. Otherwise, warranty claims are excluded. 3. Notices of defects from the customer must be in writing to be effective. Otherwise, the customer's warranty claims are governed by the statutory provisions. § 7 Liability 1. Claims for damages by the customer expire three months after the contractually agreed end of the treatment, unless the claims are asserted within this period. After this period, the customer may only assert claims if they were prevented from complying with the deadline through no fault of their own. 2. All claims for damages become statute-barred one year after they arise. This does not apply to claims arising from tort. 3. Our liability, as well as that of our employees and agents, for breaches of contractual obligations and for torts is limited to intent and gross negligence. This does not apply in the event of a breach of a material contractual obligation, i.e., an obligation whose fulfillment is essential for the proper performance of the contract and on whose compliance the customer relies and is entitled to rely. In cases of slight negligence, however, liability is limited to compensation for foreseeable damages that typically occur. 4. The aforementioned limitations of liability do not apply to claims under the Product Liability Act, other statutory warranty liability, or claims for injury to life, body, or health.
5. Pigmentation
No guarantee is given for durability, color intensity or exact shade, as these depend individually on skin type and metabolism.
The treatment is carried out at the customer's own request and is a contract for work and services in accordance with §631 BGB.
Section 8 Service Subscriptions, Skin Care Concepts & Installment Payments 1. The institute offers the option of installment payments for certain treatment and care concepts. 2. This agreement applies exclusively to service subscriptions (e.g., skin care concepts over an extended period). 3. With the commencement of the first treatment, the contract is considered fully commenced in accordance with Section 611 of the German Civil Code (BGB), as the services are provided continuously and are interconnected. 4. Cancellation after the commencement of treatment is excluded, as the services are individually tailored and scheduled for the client in accordance with Section 312g Paragraph 2 No. 9 of the German Civil Code (BGB).
5. When booked, pigmentation services are a contract for work and services in accordance with §631 BGB and are therefore binding.
Section 9 Disclaimer of Liability 1. The institute is not liable for allergic reactions or skin reactions caused by unknown intolerances. 2. The client is obligated to inform the institute of any existing allergies, illnesses, medications, or other relevant circumstances before each treatment. 3. The institute assumes no liability for clothing, valuables, or devices brought to the client's premises. Section 10 Right of Withdrawal 1. For online or distance contracts for products, the statutory right of withdrawal of 14 days from receipt of the goods applies. 2. Treatments that take place on-site at the institute are excluded from the right of withdrawal, as these are individually scheduled services (Section 312g Paragraph 2 No. 9 of the German Civil Code). Section 11 Final Provisions 1. Should individual provisions of these Terms and Conditions be invalid, the validity of the remaining provisions shall remain unaffected. 2. German law applies. The place of jurisdiction is Berlin, to the extent legally permissible.
