You should use products which strengthen and moisturize the nails, delivering high-shine color. However, you should ensure that the product is evenly applied, and is toluene-free, DBP-free and formaldehyde-free. Le Vernis Nail Colour Desirio and Le Vernis Nail Colour Paradiso are examples of good products for the nails. After the first application, the nails should be allowed to dry and the color reapplied again until you achieve the intensity desired.
You should use serums instead of moisturizers, as the skin can quickly get oily during the warmer months. Moisturizers are known for making the skin to be greasy, while serums penetrate the skin better for hydration.
Another spring makeup idea is to exfoliate the skin, though this should be done in moderation. It should be done about 3 times a week. A cheap way of doing this is using a mixture of olive oil and brown sugar.
