For lightening and unifying the skin tone in sensitive areas like the knees and elbows, you’ll want a lotion that targets pigmentation, smooths the skin, and hydrates it. Look for products that contain ingredients such as:

1. Vitamin C – Known for its brightening properties and ability to even skin tone.
2. Niacinamide – Helps to reduce dark spots and pigmentation.
3. Alpha Arbutin – Often used for skin lightening and evenness.
4. Lactic Acid – A gentle exfoliant that can help with darkened areas.
5. Licorice Extract – Natural ingredient that helps with lightening skin and reducing hyperpigmentation.

Some popular lotions and creams formulated for this purpose are:

• Nivea Extra Whitening Cell Repair & Protect Lotion
• Eucerin Even Pigment Perfection Body Lotion
• Jergens Natural Glow Firming Daily Moisturizer
• Fair & Lovely (Glow & Lovely) for targeted dark spots
