Answer to Your Question

If you are looking for ready-to-use products that do not require mixing yourself, you can choose from the formulations already prepared by the shop. Typically, full-size ready-to-use products are not referred to as "testers," which are usually sample sizes. You can identify them by the product name and description.

Based on your interest in anti-aging skincare products and Salicylic Acid (BHA) toner, the shop has some ready-to-use products that might suit your needs.

Ready-to-Use Anti-Aging Products

• Hyalu B5 Serum (Compare Roche-Posay): A serum with two molecular weights of Hyaluronic Acid and Vitamin B5, targeting fine lines, plumping, and hydration.
• Specialist B3 Serum (Compare To Vichy Liftactiv): A serum containing 5% Niacinamide and other ingredients to help with wrinkles, dark spots, and uneven skin tone.
• Pro Acne Solution Post-Acne Marks Reduction (Compare Eucerin): A serum for acne-prone skin containing Salicylic Acid and ingredients that help reduce acne scars, brighten skin, and control oiliness (offers anti-aging benefits by improving skin condition).

Adding Additional Ingredients

Regarding whether adding other ingredients to ready-to-use gels or BHA products offered by the shop will reduce their effectiveness, it depends on the type and concentration of the ingredients you wish to add. Mixing different substances in cosmetic formulations is complex and requires considering the compatibility of each ingredient, the formula's pH, and other factors to ensure the active ingredients work effectively and the formula remains stable.

If the shop provides options to add certain ingredients to a ready-to-use base, these are usually ingredients that have been tested for compatibility and are not expected to reduce the base's effectiveness. It is recommended to ask for details or consult directly with the shop about the available ingredient options and expected results to ensure the final product meets your needs and is maximally effective.
