It is all retrievable. I'm 48 and look younger now than I did at 39.
What works for me - brace yourself
Be at least 1/2 stone more than your normal for you weight
No sugar - seriously none
Protein and fats with every meal but low carb (veg and fruit are the only carbs I eat now really)
Collagen protein powder every morning in my spinach smoothie - it really firms my skin
The Ordinary Ascorbic acid powder mixed into SPF 50. I had never used vit c before thinking it was just for pigmentation, but it's really firming.
A retinol product at night
Nu Face 2 minutes every morning
Abigail James on YouTube Face Massage at least 3 x week
Dermawand for 5 minutes every morning - this is a radiofrequency device for home use. I've paid for courses of RF at salons in the past and they are effective but time consuming and costly. I prefer to do it daily as finds it keeps everything up.
LED mask Red light. 10 minutes every night - I can tell if I miss a go as in the morning, skin isn't as springy.
No sugar I've repeated it as it's the most important thing - google glycated collagen to persuade you.
Minimal alcohol/no alcohol. I struggle with no alcohol but definitely look waaaay worse even after 1 drink the next day - haggard and face droopy nit to mention that it also makes me crave carbs which are a no no!
20-30 minutes weight training daily. I follow Rachel Holmes on YouTube and face looks all glowy and lifted afterwards - more defined jaw.
Water. at least 1.5l dayl
Make up wise, avoid foundations and concealers if you can - they are very ageing on me. I love Mac strobe cream and a highlighter all over my cheek area to plump it out and make it look more round.
And obviously sleep - I need 8-9 hours these days.
You will be fine.
