SOSKIN offers a lightening serum designed specifically for addressing dark spots and uneven skin tone, especially suitable for oily skin types. These serums typically contain ingredients that target pigmentation and help brighten the skin without clogging pores or adding excess oil.

Some common ingredients you might find in such a serum include:

1. Vitamin C – Known for brightening the skin and reducing dark spots.
2. Niacinamide (Vitamin B3) – Helps to even out skin tone and reduce pigmentation.
3. Alpha Arbutin – A skin-brightening agent that targets hyperpigmentation.
4. Salicylic Acid – A gentle exfoliant that can also help regulate oil production, making it great for oily skin.

This serum would help to lighten dark spots, provide an even skin tone, and balance oily skin without causing breakouts or irritation.
