We compared two supermarket-staple lip balms: the Vaseline Lip Therapy Original and the NIVEA Original Care Lip Balm.

What we looked at

Listed protection, main ingredients, moisture claims, size, and price including price per gram.

The verdict

If you want a lip balm with SPF 15 against UVA and UVB rays, made with petroleum jelly and pro-vitamin E, the Vaseline Lip Therapy is the sun-protection pick, at £2.49 for 4g. If you would rather pay less, £1.75 for 4.8g (about 36p a gram against 62p), for a shea-butter formula with 100% natural origin ingredients and a stated 24-hour moisture, the NIVEA is the value option, though its listing does not mention SPF.
