Short version

Story in brief

Oily skin is a skin type, not a problem. It's characterized by overactive sebaceous glands that produce more oil than other skin types. This has both advantages and disadvantages.

The advantages are significant: oily skin ages slower because natural oil keeps the skin plump and protects the barrier. It also retains moisture better and is more resistant to environmental damage.

The disadvantages are well-known: oily skin is more prone to breakouts and congestion, pores appear larger, and it can be challenging to find products that work without making it worse. But these challenges can be managed with the right approach.
