Ingredients Explained
These ingredients are found in both products.

Lanolin is a waxy substance secreted by the sebaceous glands of wool-bearing sheep. It is an effective moisturizer that works as both a humectant and emollient.
As a humectant, it is able to absorb up to 400% of its own weight in water; this also gives it emulsifying properties as it can help stabilize water-in-oil emulsions.
On the other hand, lanolin is able to reduce transepidermal water loss (TEWL) by about 20-30%. It can also incorporate into the lipid matrix to surround skin cells and reinforce the skin barrier.
This is why you'll see lanolin as an ingredient for heavy-duty moisturizers.
You might have seen an "allergy concern" that gives lanolin a bad reputation. The rate of lanolin contact allergy in the general population is estimated to be under 0.5%, and most of these are seen in people with compromised-skin dealing with eczema, atopic dermatitis, or leg ulcers.
Healthy, intact skin tolerates lanolin well. Even people who have previously reacted to it test negative on patch tests when the test is done on normal skin.
Because lanolin comes from an animal, it is not considered vegan. Sheep secrete lanolin through sebaceous glands to help protect their skin from the environment.

Peppermint oil is a "feels amazing" ingredient until it doesn't.
At higher doses or for those with sensitive skin, methol-type cooling can quickly turn into burning/irritation. It can also trigger irritant dermatitis or even allergic contact dermatitis. In a large patch-test dataset, peppermint oil had a low but positive rate for this.
In cosmetics, Cosmetic Safety Reviews (CIR) concludes that peppermint oil is safe to use when formulated to be non-sensitizing with some restrictions; for instance, pulegone, a naturally occurring component of peppermint oil, should not exceed 1%.
Since peppermint oil contains fragrance allergens such as limonene, linalool, and menthol, it can be sensitizing for those with rosacea, eczema, a broken skin barrier, or just sensitive skin in general.
In Japan, this ingredient is known as Hakka Yu.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.
