Compared to the rest of the body, skin on the legs does not produce the same amount of melanin, which results in legs getting less tan. Skin on the legs is thicker and harder and the UV light from the sun or sunbeds cannot easily penetrate it.
The skin on most areas of your legs is thicker and harder than the rest of your body and ultraviolet (UV) rays can't easily penetrate it. The skin here is also dryer, resulting in quicker exfoliation of the outer layers. On top of that, dry skin deflects UV light, making the whole tanning process less effective.
Here are a couple of questions to ask yourself that might explain why your calves won't tan: Is there any residue left on your calves from products like moisturiser, shaving foam or body oil? All these cosmetic products act as a barrier to fake tan and can prevent the skin from 'grabbing' colour.
Exfoliate: Before tanning, exfoliate your legs to remove dead skin cells. This helps your skin absorb sunlight more effectively. Use Sunscreen: Apply a broad-spectrum sunscreen with SPF to protect your skin from harmful UV rays. This prevents sunburn and promotes a safer, more gradual tan.
Just don't use a product with mineral oil, plant oils are fine and won't ruin your tan. Put a drop of oil (safflower, jojoba, coconut,etc) right under your kneecap and use your fingers to spread it down the front of your leg. Or, just use powder highlighter like you would on your face.
Make Sure Skin Is Completely Dry
Most experts recommend showering before applying self-tanner as this is the best way to ensure skin is clean and free of any oils or products that could interfere. But it's important not to rush into tanning straight away.
Therefore, what will determine whether a person can tan or simply turn red is both the amount of melanin produced by their skin cells and its quality. Or, the ratio between “good and bad” melanin.
Hydrated skin will not only tan better but will also keep its colour for longer. Moisturise your skin twice daily to prepare your skin for the sunshine and get that long-lasting tan. Dry skin can lead to a peeling and uneven sun tan and so is effectively the enemy.
Avoid shaving immediately before your spray tan session. Ideally, shave 24 hours prior to allow your skin to recover and avoid any potential irritation. Exfoliate gently: If you're shaving before tanning, gently exfoliate your skin using a mild scrub or exfoliating glove.

Tinted body lotions
Tinted body lotion offers the easiest of all methods to get tanned legs. What the BB cream for the face is, is a tinted body lotion for the legs. Simply apply and you are done. No waiting, no spots.
You may be surprised to learn that there is a limit to how much your body can tan in a day. Past that point, your body can't produce any more melanin. Meaning your skin won't get any more bronze or olive-hued, but it will still be susceptible to sun damage.
Problem 1 - the skin on the legs has fewer sebaceous glands which are what provides moisture. Problem 2 - there are fewer melanocytes in the legs. These are what stimulate melanin production. Problem 3 - dead skin cells form a barrier to UV radiation and lotions.
Moist skin will tan better and more evenly than dry skin. Your skin knows that moisture is important and uses a variety of methods to retain moisture in its surface. Your skin retains water within its natural oils to help them maintain an ordered structure around each skin cell.
The reason you don't tan is because you don't have enough melanin in your skin. Melanin is the tanning colour in our skin. When we go in the sun it is produced to protect our skin. The evolutionary advantage of white skin was that, when there was seldom any sun; skin started to produce less melanin.
You don't necessarily tan faster in water or laying out. This is because water reflects UV rays, so you may not be getting as much exposure as you think if you're actually in the pool.
Some people have a perfect tanning gene, while others may never get the tan they want no matter how hard they try. Whether your skin tans or burns after sun exposure depends on your level of melanin pigmentation (shown by how dark your skin is or can get).
