I think it is a big fat con. Not sunbathing, using sun beds and good genes are the key. Ask a dermatologist.
I do see a dermatologist. I have asked her.
She doesn't think a skin routine is a con. Although she thinks lots on the high st is a total waste because it's not actually formulated to be effective.
She advocates a simple skincare routine but with key active ingredients.
To be really effective, these will often need to be prescription strength
She does not advocate for baby wipes and soap
She also doesn't advocate for a million steps
She stripped my routine right back as I was using lots of different products and she wanted to go back to basics
AM
Cleanse with a gentle non foaming SLS free cleanser.
At the moment I'm using Duac (prescription topical benzoyl peroxide / antibiotic gel) after my morning cleanse, but the aim is to swap this for Skinoren (prescription azelaic acid)
Then moisturise and SPF 50
PM
She said double cleansing isn't necessary as long as you do a proper cleanse (as in, properly massaging the cleanser in to really get the grime out) - I take my makeup off first with micellar water first though, and then cleanse to actually clean my skin
Then prescription retinoid. At the moment it's one formulated for acne (Treclin - tretinoin and antibiotic). Aim is to swap for pure tretinoin if we can crack the acne, as that's better for maintenance and anti ageing!
My skin has been utterly transformed
The high St serums etc didn't work, but actual proper medical strength stuff did
Nice for those of you boasting that you look half your age and think skincare is a con - not all of us are as lucky as you
