The lips are a common and often missed spot for sun damage. The lower lip gets the most direct sun, and skin cancer there tends to behave more aggressively than on the rest of the face. Most people never put sunscreen on their lips.
A lip balm with SPF helps, but only if you use it like sunscreen. That means a full layer and steady reapplication through the day. A thin, one-time swipe in the morning does very little by lunchtime.
The catch with any flavored lip product is that flavor and fragrance are common triggers for irritation and allergy on the lips. If your lips stay sore, red, or flaky, the balm you are using to help them may be the cause.

The avobenzone in this is properly stabilized, and that is a real, technical advantage worth paying for.
Avobenzone is the main UVA filter available in the US, and it is fragile — it breaks down in sunlight unless it is protected. Supergoop includes octocrylene and a naphthalate stabilizer, both of which do that job.
Jack Black's lip balm pairs avobenzone with octinoxate, which destroys it. Supergoop got this right and they did not.
SPF 30, and it goes on smoothly.
Lip protection matters more than people think — see below.
It contains fragrance, and it is sold on a "clean" brand identity. The ingredient list includes a full flavour and fragrance complex. Flavoured lip balm on chapped lips is a common trigger for allergic cheilitis — an allergic reaction on the lips, caused by the thing you are putting on them to help.
The "oxybenzone- and octinoxate-free" positioning is a half-truth. It swaps them for homosalate and octocrylene. Both are currently under FDA review with incomplete safety data, and homosalate is restricted in the EU to a lower concentration than US products typically use. If you are avoiding chemical filters for safety reasons, this product does not solve that.
There is no mineral option in the line, for people who want zinc on their lips.
People consistently say it tastes like sunscreen. That sounds trivial. It is not — a lip SPF you dislike is a lip SPF you will not reapply, and reapplication is the entire game.

Photostabilization, triplet quenching and reactivity with singlet oxygen (https://doi.org/10.1039/b9pp00158a) — Directly studies avobenzone photostability in combination with other UV filters including octocrylene and octyl methoxycinnamate, supporting the claim that filter pairings can either stabilize or accelerate breakdown of avobenzone. 2. Relevance of UV filter/sunscreen product photostability to human safety (https://doi.org/10.1111/phpp.12113) — Explicitly identifies octyl methoxycinnamate (octinoxate) plus avobenzone as a photo-unstable combination, backing the claim that octinoxate destabilizes avobenzone. 3. 3-(3,4,5-Trimethoxybenzylidene)-2,4-pentanedione: Design of a novel photostabilizer with in vivo SPF boosting properties and its use in developing broad-spectrum sunscreen formulations (https://doi.org/10.1111/ics.12344) — Confirms octocrylene is an established commercial photostabilizer used to protect avobenzone from UV-induced degradation, supporting the claim that octocrylene stabilizes avobenzone. 4. Sunscreen: How to Help Protect Your Skin from the Sun (https://www.fda.gov/drugs/understanding-over-counter-medicines/sunscreen-how-help-protect-your-skin-sun) — FDA lists avobenzone among approved sunscreen active ingredients and explains broad-spectrum products protect against UVA, supporting that avobenzone is a US-recognized UVA filter.
