During my own experience with the 75 Hard challenge, I faced a similar dilemma about skincare purchases. The 75 Hard program emphasizes mental toughness and creating disciplined habits, which often leads to personal questions about what counts as 'shopping.' When I started, I had specifically excluded clothes, shoes, and makeup from my shopping ban, thinking skincare might be an exception. I found that buying skincare products felt a bit like a gray area since it contributes to self-care rather than vanity, but it technically involves spending money on consumer goods. In my case, I decided to differentiate between skincare essentials (like cleanser, moisturizer, or sunscreen) and non-essential cosmetic items. I allowed myself to replace essentials only when necessary, avoiding impulse buys or trendy products. One useful tip is to set clear definitions and rules before starting your challenge. For example, if your rule is 'no clothes, shoes, or makeup,' explicitly stating whether skincare falls outside these categories helps avoid confusion and keeps you aligned with your goals. Additionally, consider whether your skincare purchases support your health and well-being rather than just aesthetic enhancement. Visiting K-beauty pop-ups or specialty stores, like one I recently attended, reinforces the excitement of trying new skincare. However, balancing enthusiasm with discipline is key. To maintain integrity, I tracked my purchases and ensured they were replacements, not additions. Ultimately, the 75 Hard challenge is about mental strength and honesty with yourself. Defining your shopping boundaries with clarity, including how skincare fits in, will empower you to stick to the challenge while caring for your skin thoughtfully and sustainably.
