Should skincare products from different brands be combined for a systematic routine? (Review)

The modern cosmetics market has a significant number of companies offering various skin, hair and body care products. However, the question of whether it is worth combining products from various brands or sticking to a single product line remains relevant. Objective — to summarize and compare information on the use of skincare products from a single brand versus multiple ones. Materials and methods. Relevant sources on the systematic use of skin care products were searched online using systemic, bibliosemantic, and analytical methods. Inclusion criteria were meta-analyses, literature reviews, original studies, and official publications in professional journals. Results and discussion. The interaction between cosmetic ingredients is a complex and crucial aspect of developing effective products. Understanding how ingredients affect each other allows us to create safe and effective formulas. The advantages of using products from a single brand include product compatibility, balanced care, efficiency, reasonable choice, and consistency in care.The phenomenon of synergism is widely used to create products that are more effective in achieving desired results, such as moisturizing, skin brightening, or combating signs of aging. For instance, the combination of stabilized vitamin C and vitamin E can enhance the skin’s antioxidant defense since these components support and restore each other’s actions, providing better protection against free radicals.Potential side effects of using incompatible cosmetic products from different manufacturers include irritation and allergic reactions, changes in skin pH, photosensitization, unpredictable chemical reactions, disruption of the skin barrier function, increased skin sensitivity, comedogenicity, reduced product effectiveness or neutralization of effects, chemical burns and skin damage, psychological discomfort and dissatisfaction with results.A systematic skincare regimen of the same company is key to achieving desired results, including addressing specific concerns such as age-related changes, pigmentation, inflammation, and increased skin sensitivity. Conclusions. Skincare products designed for combined use are more effective due to the synergistic effect. The consistency of ingredients and formulations within a single product line ensures a synergistic action that enhances the overall effectiveness of skincare. Given the specific needs of the skin, a systematic regimen from a single brand can be the optimal choice for achieving maximum results and ensuring long-term skin health.
