Can you do a Tiktok on the harmful effects of sun screen. 🙏🏽

Hiii…love your vids..one minor correction is that retinol does not actually make your skin more sensitive to the sun or burning…it does not impact your minimal erythema dose…in fact consistent use of retinol actually improves your skins ability to withstand sun damage

alexvenm :

Do you use tretinoin

J :

can I combine retinol and vit C?

Thom :

Thanks
