Well for makeup and beauty products, my favorite brand is MAC Cosmetics. Because it fulfills all my makeup shopping needs. Mac is the best company that offers awesome products like-nail paint, Matte lipsticks, lip color, eye shadow, face wash, cream, and compact, etc. Mac products are good.
The brand would certainly say Yes, but they want you to keep buying. It depends which product you're talking about. Rescue remedies are examples of one-off, or rare use. Moisturiser is necessary for most skins every day, but does it have to be the brand you've just bought? Unlikely. Most people gravitate to a brand that suits them in performance and price. Other products such as deep cleansers are for occasional use for those with clear skin, but may be needed regularly for those with muddy skin or blackheads.
The main thing is to go by results. You know whether something has had beneficial results from looking in the mirror. Don't be bullied by aggressive advertising suggesting that your appearance will deteriorate without regular use of a product. Common sense prevails, but in addition, a well-known brand is unlikely to do you any harm if you follow the instructions.
