So I found this chart on the skincancer.org website. I guess it says SPF15 is fine for us with Skin type IV++
Type I: You always burn and never tan in the sun. You are extremely susceptible to skin damage as well as cancers like basal cell carcinoma and squamous cell carcinoma. You are also at very high risk for melanoma, the deadliest type of skin cancer. Generally follow The Skin Cancer Foundation’s prevention tips but use a sunscreen with a SPF of 30+ and clothing with a UPF rating of 30 or higher. Seek the shade whenever you are out in the sun. Check your skin head-to-toe each month, paying careful attention to any suspicious growths, and make sure you have an annual professional skin checkup.
Type II:
You almost always burn and rarely tan in the sun. You are highly susceptible to skin damage as well as cancers like basal cell carcinoma and squamous cell carcinoma. You are also at high risk for melanoma, the deadliest type of skin cancer. Generally follow The Skin Cancer Foundation’s prevention tips but also consider using a sunscreen with a SPF of 30+ and clothing with a UPF rating of 30 or higher. Seek the shade whenever you are out in the sun. Check your skin head-to-toe each month, paying careful attention to any suspicious growths, and make sure you have an annual professional skin checkup.
Type III: You sometimes burn and sometimes tan in the sun. You are susceptible to skin damage as well as cancers like basal cell carcinoma and squamous cell carcinoma. You are also at risk for melanoma, the deadliest type of skin cancer. Be sure to apply a sunscreen with an SPF of at least 15 every day, wear sun-protective clothing, and seek the shade between 10 AM and 4 PM, when the sun is strongest. Check your skin head-to-toe each month, paying careful attention to any suspicious growths, and make sure you have an annual professional skin checkup.
Type IV: You tend to tan easily and are less likely to burn. But you are still at risk; use sunscreen with an SPF of 15+ outside and seek the shade between 10 AM and 4 PM. Follow all other Prevention Tips from The Skin Cancer Foundation as well. Check your skin head-to-toe each month, paying careful attention to any suspicious growths, and make sure you have an annual professional skin checkup.
Type V: You tan easily and rarely burn, but you are still at risk. Use sunscreen with an SPF of 15+ and seek the shade between 10 AM and 4 PM. Acral lentiginous melanoma, a very virulent form of the disease, is more common among darker-skinned people. These melanomas tend to appear on parts of the body not often exposed to the sun, and often remain undetected until after the cancer has spread. Check your skin head-to-toe each month, paying careful attention to any suspicious growths, and make sure you have an annual professional skin checkup. Keep an eye out for any suspicious growths, especially on the palms, soles of the feet and mucous membranes.
Type VI: Although you do not burn, dark-skinned people are still at risk for skin cancers, and should wear sunscreen with a SPF of 15+ and seek the shade between 10 AM and 4 PM. Acral lentiginous melanoma, a very virulent form of the disease, is more common among darker-skinned people. These melanomas tend to appear on parts of the body not often exposed to the sun, and often remain undetected until after the cancer has spread.
