However, according to dermatologists, consumers should not place absolute trust in advertisements or experiences shared online.
BS.CKII Vo Thi Doan Phuong, Head of Clinical Department 3, Ho Chi Minh City Dermatology Hospital, said that cosmetic review videos only reflect the experiences of one or a group of people over a certain period of time. The effectiveness of the product also depends on many factors such as skin type, age, skin condition, living environment and how to use it.
One product may be effective for one person but not suitable, and may even cause irritation for another," said Dr. Phuong.
According to experts, many review videos are actually advertising or commercial cooperation content, but are not always clearly shown. In addition, images in videos may be affected by light, camera angles, filters or editing tools, making the skin look better than it actually is. Therefore, consumers should only view reviews as a reference source instead of a single basis for choosing products.
Explaining why the same product is used effectively by some people and irritated by others, Dr. Phuong said that no cosmetics are suitable for everyone. Each person has a different skin type and skin condition.
For example, a moisturizing cream can help restore dry skin but increase the risk of clogged pores in people with oily skin. Similarly, strong active ingredients such as retinol or BHA can be effective for people with healthy skin but easily cause redness, burning or irritation in people with sensitive skin.
In addition to constitutional factors, product use also affects effectiveness. Applying too much, using too often, or combining many strong active ingredients at the same time can increase the risk of skin irritation.
Faced with the trend of buying cosmetics according to "hot trend" products, Dr. Phuong recommends consumers to be cautious. According to her, a famous product on social networks is not necessarily proven effective by scientific evidence. Many products become popular thanks to strong promotion campaigns or spreading effects on social networks.
Consumers should not choose cosmetics just because the product is mentioned a lot. The important thing is whether the product is suitable for their needs and skin condition or not," the doctor emphasized.
According to dermatologists, when choosing cosmetics, consumers need to prioritize criteria such as safety, ingredients suitable for the skin condition, clear origin and distribution by reputable units. At the same time, products need to have full information about ingredients, instructions for use and anti-counterfeit stamps.
Regarding the form of buying through livestream, Dr. Phuong recommends that young people should not buy cosmetics based on emotions or follow shocking discount programs. Before deciding to buy, it is necessary to carefully study the ingredient list, only choose products from genuine stores and avoid using many new products at the same time.
Especially, for people who are experiencing skin problems such as inflammatory acne, melasma or atopic dermatitis, self-purchasing cosmetics according to online advertisements can make the condition worse. In these cases, people should go to a dermatology specialist facility for examination and appropriate advice.
